Optoma UHD 40 / 50 3D Vision Projector (1920x1080 @120Hz)
1 / 13
I thought it's time to open a topic about this projector and summarize all infos for people who are interested in buying it.
So far it's the only projector known to work in [b][color="orange"]1920x1080[/color] @ [color="orange"]120hz[/color][/b] and [b][color="orange"]3D Vision[/color][/b] mode.
[b][color="orange"]Update:[/color][/b] Optoma recently introduced a new 1080p projector "Optoma HD27HDR" which also supports 1920x1080 @120hz in 3D mode. Please have a look at [url=https://forums.geforce.com/default/topic/1107119/3d-vision/the-ultimate-nvidia-3d-vision-dlp-display/1/]this topic[/url] for more information.

[u]Requirements for 3D:[/u]
For using this projector with 3D Vision you additionally need this:
[list]
[.]PC with Nvidia graphics card[/.]
[.]3D Vision Emitter (it only servers as a license dongle. It's sold with the [url=https://www.amazon.de/nVidia-Vision-Schwarz-1St%C3%BCck-Steroskopische/dp/B005XULTG6/ref=sr_1_3?ie=UTF8&qid=1542270174&sr=8-3&keywords=3d+vision+kit]3D Vision 2 Kit[/url])[/.]
[.]DLP glasses (see FAQ for recommendations which one to buy)[/.]
[/list]
[u]Step by step instructions how to make 3D work:[/u]
[olist]
[.]Connect one of the HDMI ports of the projector to the HDMI port of your graphics card.[/.]
[.]Connect the 3D Vision emitter (pyramid) to your PC via USB cable[/.]
[.]Turn on the projector and open Nvidia Control Panel (right click desktop / Nvidia Control Panel)[/.]
[.]Go to [i][color="orange"]"Set up multiple displays"[/color][/i] and untick all devices except for [i][color="orange"]"Optoma UHD"[/color][/i][/.]
[.]Click on button [i][color="orange"]"Apply"[/color][/i]. You should see your Windows desktop on the projector screen now[/.]
[.]In Nvidia Control Panel click on [i][color="orange"]"Set up Stereosopic 3D"[/color][/i][/.]
[.]Tick option [i][color="orange"]"Enable stereosopic 3D"[/color][/i][/.]
[.]If 3D Vision isn't set up yet a setup wizard is automatically started. Choose 3D Vision there (not anaglyph) and complete the wizard. If it's already configured just make sure [i][color="orange"]"Generic CRT"[/color][/i] is selected from the list.[/.]
[.]If the 3D Vision setzup wizard fails to be completed then look down at the section [i][color="orange"]"Trouble Shooting"[/color][/i][/.]
[.]Start a game[/.]
[.]Make sure ingame resolution is set to 1920x1080 @120hz[/.]
[.]On your remote control press the [i][color="orange"]"3D"[/color][/i] button to turn on 3D mode / DLP sync flash[/.]
[.]Turn on your DLP glasses[/.]
[.]If eyes are swapped then press CTRL + T several times until it's fixed. Alternatively you can toggle 3D on / off a few times with your remote control. Another more advanced option is to use 3dmigoto for reversing eyes. I don't recommend to use the Reverse 3D function of the projector itself as it's faulty. See section "How to fix swapped eyes in 3D mode" for more info on this topic[/.]

[.]Click on the [i][color="orange"]"3D"[/color][/i] toggle in the top right corner[/.]

[u]How to fix swapped eyes in 3D mode:[/u]
When starting a game in 3D mode you will often run into the trouble that sometimes 3D looks correct and other times when restarting the game you would have to wear your glasses upside down to see proper 3D. Is there are a trick to fix this issue permanently? Unfortunately the answer is no. Due to the nature of frame sequential 3D mode the projector can't know which frame belongs to which eye. So every time you start a game in 3D mode you will have a 50% chance that the eye order is correct.
[color="orange"]How to correct wrong eye order:[/color]
There are several ways to fix wrong eye order. I will present all of them to you - so it's up to you which way you prefer.
[u]Method 1 (my preferred way):[/u]
[olist]
[.]Press CTRL + T. This tells the Nvidia driver to disable 3D[/.]
[.]Press CTRL + T again. 3D is re-enabled and with a chance of 50% the eye order is fixed now[/.]
[.]Repeat step 1 and 2 until eye order is correct[/.]
[.]For very rare games CTRL + T doesn't work (I think only Rise / Shadow of the Tomb Raider are affected). In this case try method 2 or 3 to fix eye order[/.]
[/olist]
[u]Method 2:[/u]
[olist]
[.]Press button [i][color="orange"]"3D"[/color][/i] on your remote control and turn off 3D[/.]
[.]Press the button again to re-enable 3D.[/.]
[.]Repeat step 1 and 2 until eye order is correct[/.]
[/olist]
[u]Method 3 (only available with DirectX 11 games):[/u]
[olist]
[.]Open 3D Fix Manager[/.]
[.]Go to tab [i][color="orange"]"Settings"[/color][/i] and click on sub-tab [i][color="orange"]"Display Profiles"[/color][/i][/.]
[.]For the projector profile tick option [i][color="orange"]"Link profile to display"[/color][/i] and choose [i][color="orange"]"Optoma UHD"[/color][/i] from the list (when doing so the projector profile is automatically chosen when you play games on this device)[/.]
[.]Tick option [i][color="orange"]"Preferred 3D format"[/color][/i] and choose [i][color="orange"]"Regular 3D Vision (frame sequential)"[/color][/i] from the list. This option also unlocks a Hotkey ingame for choosing different 3D formats. One of them is reversed frame sequential.[/.]
[.]Go to tab [i][color="orange"]"Installation"[/color][/i] and in the left upper corner of the window change the default filter from [i][color="orange"]"All Fix Types"[/color][/i] to [i][color="orange"]"3dmigoto"[/color][/i]. By doing so only DirectX 11 games are shown in the list[/.]
[.]Select the game you want to play and click on button [i][color="orange"]"Play 3D"[/color][/i][/.]
[.]If eyes are swapped ingame press F11 once. Eye order is fixed 100% now[/.]
[.]If you have accidentially pressed F11 too often just press it a few times more until you are back at the 3D format you want (F11 just cycles through 8 different 3D formats)[/.]
[/olist]
[color="orange"]Note:[/color] Using this technique adds more latency and overhead. That's the reason I don't use it. But if you are fine with that extra latency you have a very easy and reliable method for fixing reversed eyes with just one single button press.
[u]Method 4 (not recommended):[/u]
[olist]
[.]Press button [i][color="orange"]"Menu"[/color][/i] on your remote control[/.]
[.]Go to sub-menu of [i][color="orange"]"3D"[/color][/i][/.]
[.]Select [i][color="orange"]"3D sync invert"[/color][/i] and set it to [i][color="orange"]"On"[/color][/i][/.]
[/olist]
[color="orange"]Note:[/color] Using the 3d sync invert feature of the projector itself can really cause headaches and introduce artefacts like a vertical tearing line. I highly recommend NOT to use this feature! In my opinion it's completely broken.
[u]How to fix intermittent eye swapping in 3D mode:[/u]
In rare cases the projector starts swapping eyes in 3D mode every 10-15 seconds. This means that you would have to turn around the 3D glasses every few seconds which is unacceptable.
There is a simple fix for this:
[olist]
[.]Switch to the other HDMI channel. So if HDMI 2 is active just press [i][color="orange"]"HDMI 1"[/color][/i] on your remote control.[/.]
[.]Switch back to HDMI 2 by pressing [i][color="orange"]"HDMI 2"[/color][/i] on your remote control[/.]
[/olist]
If HDMI 1 is your active HDMI port you have to do the reverse thing. The issue should be fixed then.
[u]Correcting 3D depth:[/u]
When playing in stereo 3D mode you will probably notice that 3D depth is far too high even if you lower 3D separation to 50%. The reason for this is in the Nvidia driver which assumes that you play on a 17 inch CRT monitor in Generic CRT mode. So in other words the 3D depth is optimized for a very small display and this results in a 3D depth which is far too high. We can fix this by telling the driver that we actually play on a 100 inch (or taller) sized projector screen.
Please follow these steps to correct 3D depth:
[olist]
[.][url=https://forums.geforce.com/default/topic/986926/3d-vision/3d-fix-manager-application-for-installing-3d-vision-fixes-hotkey-editing-support/]Download[/url] 3D Fix Manager and start it[/.]
[.]Go to tab [i][color="orange"]"Settings"[/color][/i] and click on sub-tab [i][color="orange"]"Display Profiles"[/color][/i][/.]
[.]For the projector profile tick the option [i][color="orange"]"Screen size"[/color][/i] and enter the size of your projector screen in inches[/.]
[.]For the projector profile tick option [i][color="orange"]"3D display type"[/color][/i] and choose [i][color="orange"]"3D Vision / 3DTV Play / Generic CRT"[/color][/i] from the list[/.]
[.]Tick option [i][color="orange"]"Link profile to display"[/color][/i] and choose [i][color="orange"]"Optoma UHD"[/color][/i] from the list (when doing so the projector profile is automatically chosen when you play games on this device)[/.]
[/olist]
When starting a game via 3D Fix Manager now you will notice that 3D depth doesn't hurt your eyes any more and is similar to your 3D Vision monitor (if you have one). If you are also playing on a monitor or TV you should repeat the steps described above accordingly for the monitor and TV profile. When not doing this 3D depth will be wrong for those devices.
[u]Fixing washed out colors / image:[/u]
When using the projector with your PC the image might look a bit washed out and black levels aren't deep. The reason for this is that by default the Nvidia driver uses RGB color space with a limited range from 16-255. The projector however expects a RGB signal with a full range from 0-255. This dismatch makes the image look washed out.
Generally you can fix this issue either by adjusting color space in the OSD setting of the projector or by adjusting it in Nvidia Control Panel. In my opinion the best and most universal way is to leave the projector at its default setting for color space ( "Auto"). Instead we'll adjust color space in Nvidia Control. Please follow the tutorial:
[olist]
[.]Open Nvidia Control Panel (right click desktop / Nvidia Control Panel)[/.]
[.]Go to [i][color="orange"]"Change resolution"[/color][/i][/.]
[.]Enable [i][color="orange"]"Use Nvidia color settings"[/color][/i] (by default this is set to [i][color="orange"]"Use default color settings"[/color][/i] which caps color range to 16-255)[/.]
[.]Set [i][color="orange"]"Output color format"[/color][/i] to [i][color="orange"]"YCbCr 444"[/color][/i][/.]
[.]Click on [i][color="orange"]"Apply"[/color][/i] button[/.]
[.]Press the [i][color="orange"]"Menu"[/color][/i] button on the remote control of your projector[/.]
[.]Select [i][color="orange"]"Image Settings"[/color][/i][/.]
[.]Scroll down and select [i][color="orange"]"Color Settings"[/color][/i][/.]
[.]Make sure "Color Space" is set to [i][color="orange"]"Auto"[/color][/i] which is the factory default setting[/.]
[/olist]
[color="orange"]Why use YCbCr 444?[/color]
YCbCr 444 is basically a converted RGB signal and offers the same quality as RGB. By using this you have the following advantages:
[list]
[.]Washed out colors are reliably fixed for desktop, movies, games and HDR mode[/.]
[.]Color saturation and tint can be set in the OSD settings of the projector (this is not available when using RGB mode)[/.]
[.]You can leave the projector at its default value for color space ("Auto"). This would not work well if using RGB mode where you would have to set color space differently for HDR and non-HDR mode.[/.]
[/list]
But it's up to you what you prefer. Another option would be to set RGB to full 0-255 range. But as said you would have to set color saturation globally in Nvidia Control Panel then (OSD option is locked). You can also set RGB to 16-255 in Nvidia Control Panel. But then you also have to set the same color range in the OSD setting of the projector! Both settings must match!
[u]Fixing 3D issues on Windows 10:[/u]
When using Windows 10 you will run into some issues when you want to play games in 3D mode. A common issue is that some games don't start with 120 hz refresh rate which is required for 3D mode. Instead they are stuck at 60hz which you can notice by heavy flickering on the screen. Typically the Nvidia driver tries to force the required refresh rate ingame but this mechanism sometimes failes when using Windows 10. Windows 7 and 8.1 seem to be not affected by this issue.
In 99% of all cases these two steps will fix this issue:
[olist]
[.]Disable fullscreen optimizations (this is a feature which was introduced with Windows 10 v.1803). For doing things manually right click on the exe file of the game and choose [i][color="orange"]"Properties"[/color][/i]. Then click on [i][color="orange"]"Compatibility[/color][/i] tab and tick option [i][color="orange"]"Disable Fullscreen Optimizations"[/color][/i][/.]
[.]Set desktop resolution to 1920x1080 @120hz before launching a game[/.]
[/olist]
So far, so good. But this is pretty uncomfortable to change desktop resolution from 4k to 1080p every time before launching a game. And after playing we have to set desktop resolution manually back to 4K. It's also troublsome to make sure that fullscreen optimizations are turned off for every single game.
Luckily we can automate this process on a global base for all games with 3D Fix Manager.
Here is what to do:
[olist]
[.]Open 3D Fix Manager[/.]
[.]Go to tab [i][color="orange"]"Settings"[/color][/i] and click on sub-tab [i][color="orange"]"Display Profiles"[/color][/i][/.]
[.]For the projector profile tick option [i][color="orange"]"Link profile to display"[/color][/i] and choose [i][color="orange"]"Optoma UHD"[/color][/i] from the list (when doing so the projector profile is automatically chosen when you play games on this device)[/.]
[.]Tick option [i][color="orange"]"Desktop resolution 2D mode"[/color][/i] and from the lists set [i][color="orange"]3840 x 2160 @60[/color][/i] resolution[/.]
[.]Tick option [i][color="orange"]"Desktop resolution 3D mode"[/color][/i] and from the lists set [i][color="orange"]1920 x 1080 @120hz[/color][/i] resolution[/.]
[.]Look at the green text [i][color="orange"]"Game settings for 3D mode"[/color][/i] and below tick the option [i][color="orange"]"Game resolution"[/color][/i]. Next to it set [i][color="orange"]1920 x 1080 @120hz[/color][/i] resolution[/.]
[.]Click on sub-tab [i][color="orange"]"Nvidia 3D Settings"[/color][/i][/.]
[.]Tick option [i][color="orange"]"Auto disable Nvidia Stereoscopic 3D when closing games"[/color][/i][/.]
[.]Click on sub-tab [i][color="orange"]"Application Settings"[/color][/i][/.]
[.]Tick option [i][color="orange"]"Fullscreen optimizations"[/color][/i] and from the list choose [i][color="orange"]"Disable"[/color][/i][/.]
[.]Start games via [i][color="orange"]"Play 3D"[/color][/i] button in tab [i][color="orange"]"Installation"[/color][/i][/.]
[/olist]
After having configured 3D Fix Manager you will notice that desktop resolution is automatically set to 1920x1080 @120hz when launching a game. Also fullscreen optimizations are disabled in the properties of individual exe file of the game. Game should show 3D at 1920x1080 resolution which was set by 3D Fix Manager. After closing the game the desktop resolution is automatically set back to 3840x2160 @60hz (4K). Comfortable, isn't it?
[u]How to enable Nvidia DSR for 3D mode:[/u]
DSR is the acronym for [b][color="orange"]D[/color][/b]ynamic [b][color="orange"]S[/color][/b]uper [b][color="orange"]R[/color][/b]esolution. What it does is rendering the game internally in a higher resolution and scaling it down to the native resolution of the display. As a result we get a similar effect like Anti Aliasing but DSR is improving the whole picture quality while Anti Aliasing is only smoothing polygon edges. DSR is especially useful for games where no Anti Aliasing or just simple post processing mechanisms like FXAA is available.
The problem with DSR is that it always scales down to the native resolution of the display. Nvidia does not allow us to set an individual target resolution. For Optoma UHD 40 / 50 the native resolution is 3840 x 2160 but we need to scale the image down to 1920 x 1080 because higher resolutions do not support 120hz refresh rate which is required for 3D mode!
To force the driver to do a downscale to 1920x1080 we have to apply a modified EDID. An EDID contains all information about the display like the supported resolutions, refresh rates, manufacturer and so on. I've prepared a modified EDID where all 4k resolutions have been removed - by installing this EDID we can trick the Nvidia driver to think that we use a native full hd projector. DSR will downsample to 1920x1080 then.
Now you might think by applying this modfied EDID you are permanently downgrading your expensive 4K projector to a simple Full HD projector because all native 4k resolutions are gone. You are not completely wrong with your assumption! But remember that you have 2 HDMI ports on the projector. The EDID changes are only applied to one of them. If you connect the projector with 2 HDMI cables to your PC you can still use 4K resolutions by simply changing input signal to the other HDMI port where we still use the original 4K EDID! Problem solved! Of course you can revert changes anytime - nothing on the projector is changed. Only in Windows!
Please follow these steps to apply the EDID override for using DSR:
[olist]
[.][url=https://s3.amazonaws.com/duselpaul86/Optoma+UHD+40+DSR/Optoma_UHD_40_DSR.zip]Download this file[/url] and unzip it. It contains a modified EDID for the projector where all resolutions higher than 1920x1080 have been removed[/.]
[.]Connect your HDMI cable to [i][color="orange"]"HDMI 1"[/color][/i] port of your projector. By doing so we can still use the other port [i][color="orange"]"HDMI 4K"[/color][/i] for native 4K resolutions[/.]

This allows for better distinguishing between the two HDMI ports of the projector (otherwise both have the same name)[/.]
[.]Close CRU by clicking on the [i][color="orange"]"Ok"[/color][/i] button[/.]
[.]Restart your computer or run [i][color="orange"]"restart.exe"[/color][/i] (this restarts your display driver)[/.]

[u]Setting up Stereoscopic Player for watching 3D movies without 3D Vision IR emitter:[/u]
The 3D Vision IR emitter is not necessarily required when you want to watch 3D movies. [i][color="orange"]Stereoscopic Player[/color][/i] enables us to watch movies without having the emitter connected to the PC. However you can only watch 3D movies from 3D DVDs and .MKV files from your HDD. Blurays don't work with this software. For watching 3D blurays you still need both the emitter as well as Power DVD 18 Ultra.
Please follow these steps to set up Stereoscopic Player to be used independently from the IR emitter:
[olist]
[.]Set the desktop resolution to 1920x1080 @120 Hz on your projector[/.]
[.]Install [url=https://www.3dtv.at/Downloads/StereoscopicPlayer250.exe]"Stereoscopic Player 2.5"[/url] (The free version allows you to watch 3D movies up to 5 minutes. If you want to watch movies without any restrictions you can buy the software for 49€ in the [url=https://www.3dtv.at/Shop/Index_en.aspx]online shop[/url])[/.]
[.]Start Stereoscopic Player[/.]
[.]In the menu bar click on [i][color="orange"]"View"[/color][/i] -> go to [i][color="orange"]"Viewing Method"[/color][/i] and click on [i][color="orange"]"Software Pageflipping"[/color][/i] (this step has to be done on first start of the application only)[/.]
[.]In the menu bar click on [i][color="orange"]"File"[/color][/i] -> [i][color="orange"]"Open File..."[/color][/i] and choose a .MKV file (= your 3D movie)[/.]
[.]Now you are asked which 3D format is used by the movie. If you don't know what to choose just click on [i][color="orange"]"OK"[/color][/i]. We can still change this later.[/.]
[.]If you have chosen the wrong 3D format you either see two images side by side or one over the other now. If so go to [i][color="orange"]"File"[/color][/i] -> [i][color="orange"]"Layout"[/color][/i][/.]
[.]If the current movie shows two images side by side then choose [i][color="orange"]"Side by Side, Left Image First"[/color][/i]. Otherwise if it shows one image over the other choose [i][color="orange"]"Over/Under, Left Image Top"[/color][/i]. Now you should see only 1 image.[/.]
[.]If your image looks stretched go to [i][color="orange"]"File"[/color][/i] -> [i][color="orange"]"Aspect Ratio"[/color][/i] and choose [i][color="orange"]"Default, Half Width"[/color][/i] if the 3D format is Side by Side. Otherwise choose [i][color="orange"]"Default, Half Height"[/color][/i][/.]
[.]Now double click on the video to enter fullscreen. You should be able to see a stereoscopic image[/.]
[.]Turn on 3D via the remote control of your projector as well as your DLP glasses. You should see the movie in stereo 3D now[/.]
[.]If eyes are swapped press F7 to correct this[/.]
[/olist]
You should keep in mind that Stereoscopic Player is not as user friendly as Power DVD. But at least you don't need the 3D Vision emitter then.
[u][b]FAQ:[/b][/u]
[color="orange"]Is this projector called Optoma UHD 40 or Optoma UHD 50?[/color]
The projector is sold under different names depending on the country you live:
[list]
[.]In Europe the projector is called Optoma UHD 40[/.]
[.]In Northern America it's called Optoma UHD 50[/.]
[/list]
[color="orange"]Is this projector officially 3D Vision certified by Nvidia?[/color]
No. However when connecting the projector to the PC it's detected as a "Generic CRT" device which is exactly the same as 3D Vision! (just another name)
[color="orange"]Do I need the 3D Vision IR emitter for 3D gaming?[/color]
Yes. The 3D Vision emitter (pyramid) serves as a license dongle for unlocking Generic CRT mode. It has no other purpose than that. Without Generic CRT mode the 3D Vision driver wouldn't allow us to ouput frame sequential 3D content to the projector. The Nvidia glasses included in the 3D Vision 2 Kit are not required. If you're lucky you'll find a cheap emitter sold separately on ebay. Otherwise you have to buy the complete 3D Vision 2 Kit (emitter + glasses).
[color="orange"]Do I need the 3D Vision IR emitter for watching 3D movies?[/color]
This depends on the source of your 3D movie.
For watching 3D movies from your HDD (MKV file format) or 3D DVDs the 3D Vision emitter is not required. However this only works with [url=https://www.3dtv.at/Products/Player/Index_en.aspx]"Stereoscopic Player"[/url]. It's the only 3D video player which offers software page flipping which means that we don't need 3D Vision at all for outputting frame sequential 3D content to the projector. If you want to use this solution please follow the guide above to set up Stereoscopic Player.
Unfortunately Stereoscopic Player can't handle blurays. So for watching 3D blurays we still need the 3D Vision emitter as well as an alternative 3D video player capable of handling 3D blurays. I recommend [url=https://www.cyberlink.com/store/powerdvd-ultra/buy_en_US.html?affid=2581_-1_103_Shopping_PDVD-B&mkwid=s&pcrid=204555593437&pkw=&pmt=&pdv=c&gclid=CjwKCAiAlb_fBRBHEiwAzMeEdnMUiEiwRJEc5mRZCXOnvXJJ0Pg4Xbk_Z91oWARAoLlRaIrEjQMqRhoCcs8QAvD_BwE]"Cyberlink Power DVD 18 Ultra"[/url] which does this job very well.
[color="orange"]Does Cyberlink Power DVD 18 Ultra work in 3D without the IR emitter?[/color]
No. Power DVD definitely requires the emitter for 3D movies.
Stereoscopic Player is the only 3D video player which is capable of playing 3D movies without the 3D Vision emitter. But it's limited to 3D DVDs and MKV-files. Blurays are generally not supported by this player.
[color="orange"]Can I use my bluray player for watching 3D movies on Optoma UHD 40/50?[/color]
No. Bluray players use Framepacking 3D format which is not supported by Optoma UHD 40/50. You would need a bluray player capable of frame sequential format. Maybe some older bluray players or the Playstation 3 still support this.
[color="orange"]Do I need additional hardware / software for watching 3D blurays on Optoma UHD 40 / 50[/color]
Yes. For watching 3D blurays you need an internal bluray drive for your PC. I generally recommend bluray drives by LG Electronics. They only cost 50-60€, are fast, very silent and can also burn blurays / DVDs / CDs.
Of course you can also watch 3D movies from .MKV files on your HDD.
Second you need the 3D Vision emitter. As said before it's only a license dongle but without it the 3D Vision driver won't allow to output frame sequential 3D content to the pojector.
Last but not least you need a 3D video player. I recommend [url=https://www.cyberlink.com/store/powerdvd-ultra/buy_en_US.html?affid=2581_-1_103_Shopping_PDVD-B&mkwid=s&pcrid=204555593437&pkw=&pmt=&pdv=c&gclid=CjwKCAiAlb_fBRBHEiwAzMeEdnMUiEiwRJEc5mRZCXOnvXJJ0Pg4Xbk_Z91oWARAoLlRaIrEjQMqRhoCcs8QAvD_BwE]"Cyberlink Power DVD 18 Ultra"[/url] which is the best player for stereo 3D movies in my opinion.
If you just want to watch 3D movies from .MKV files on your HDD you can alternatively use [url=https://www.3dtv.at/products/Player/Index_en.aspx]"Stereoscopic Player"[/url] which is also a very good player. This player however does NOT support 3D bluray disks.
[color="orange"]Does this projector work with 3D Vision glasses?[/color]
For me 3D Vision glasses didn't sync properly with this projector. That means periodically every 5 seconds you see a lot of ghosting with 3D Vision glasses or you just have a constant ghosting.
However another user reported that his Optoma UHD 40 worked perfectly with the 3D Vision glasses. So far it's unclear why it worked for him but not for me. Either way it's worth trying the glasses - if they work reliably for you I would recommend to take them instead of DLP glasses as they have the best quality in my opinion. If 3D Vision glasses don't work then just use DLP glasses. See recommendations below which to buy.
[color="orange"]Is Nvidia 3DTV Play supported?[/color]
No because the projector does not support 3D framepacking.
[color="orange"]Is Top & Bottom or Side By Side 3D format supported?[/color]
No. Frame sequential is the only 3D format supported by the projector.
[color="orange"]Optoma does not list 1920x1080 @120hz resolution in their manual. Is this resolution really supported?[/color]
Yes. 1920x1080 @120hz is definitely supported. Optoma probably simply forgot to list the resolution in the manual.
[color="orange"]Is downsampling via Nvidia DSR supported?[/color]
Yes. However you have to apply a modified EDID first. See the guide which is located above the FAQ.
[color="orange"]Is the projector bright enough for 3D gaming?[/color]
Compared to a Lightboost monitor brightness is a bit lower (maybe 30% lower on a white 1.0 gain screen). It really depends on the screen which is used. I think with a 1.5 gain screen or higher brightness can reach the level of a lightboost monitor. It's pretty hard to compare because you can increase brightness on a monitor very strongly but then you have ghosting all over the place. If you want 0 ghosting you would have to make your monitor darker than the projector in some cases. But overall I would say the projector is less bright than a monitor in stereo 3D mode.
I have a 90 inch white diffuse 1.2 gain screen which boosts brightness a bit and in my opinion brightness is pretty good. I can play dark games like Dead Space 2 and Outlast without any issues. You should use "Dynamic Black" mode for significantly increasing brightness in 3D mode. But as said before I think a 1.5 gain screen would be perfect for 3D gaming. Brightness should reach similar levels like monitors then.
[color="orange"]How is input lag for gaming?[/color]
When playing in 120hz resolution input lag is brilliant. For HDR 4k @60hz input lag is still on a very good level as long as you don't enable Vertical Sync! I suggest to use Scanline Sync of [url=https://www.guru3d.com/files-details/rtss-rivatuner-statistics-server-download.html]RivaTuner Staistics Server[/url] which is similar to Vsync on but without the additional input lag.
[color="orange"]The projector has 2 HDMI ports. Are they both compatible to 3D?[/color]
Yes, both ports support 3D in 1920x1080 @120hz. However they differ in bandwith capacity. The "4k HDMI" port supports up to 4k @60hz and the "HDMI 1" port only up to 4k @30hz.
[color="orange"]Which HDMI cable should I use?[/color]

[/list]
If you need a longer cable you probably have to use an active HDMI repeater. I recommend [url=https://www.amazon.de/gp/product/B073CS72TH/ref=oh_aui_search_detailpage?ie=UTF8&psc=1]this HDMI repeater[/url].
[color="orange"]Which DLP glasses are recommended?[/color]
DLP glasses vary in quality, maximum brightness and whether they are able to successfully suppress crosstalk / ghosting.
Here are my recommendations / charts. For rating I gave school grades (1,0 is best and 6,0 worst). Keep in mind that you might not find each of the listed DLP glasses in your country (the list is related to German / European online shops).
[olist]
[.][url=https://www.amazon.de/gp/product/B00PLS6LCW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1]Andoer G15:[/url] (Price: 13€, Weight: 27g)

The Andoer G15 are the only DLP glasses on the market which are absolutely ghosting free. Even in high contrast scenarios you will never see any ghosting. But the quality of the frame is very poor and glasses are very small. Mine broke after a few months (I cannot attach the temples any more). You need to insert separate coin batteries (not rechargeable).

[/list]
[color="orange"]Is this projector true, native 4K?[/color]
No. Although it's advertised as a 4k projector it's not native 4k. It has a Full HD DMD chip and a 4x pixel shifter. This means that four Full HD pictures are sequentially projected to the screen which results in a combined 4K image. The shifting happens so fast that our eyes see this as one single 4K image.
[color="orange"]What about the noise level of the projector?[/color]
According to the data sheet the projector has a noise level of 25 dB which is lower than most other projectors. In my opinion this is one of the most silent DLP projectors currently available on the market. You can hear some silent buzzing due to the pixel shifting in 60hz mode which completely vanishes when you change to 120hz input signal / play in 3D.
[color="orange"]Does this projector show rainbow color artifacts?[/color]
In my opinion rainbow artifacts are very rarely visible as this projector has a RGBRGB wheel. This wheel tends to have much less rainbow artefacts than RGBCYW wheels. Of course it also depends on the individual person if he / she is sensitive to those artefacts but I am very happy with it.
[color="orange"]Does the projector support upscaling?[/color]
Yes. For 2D mode WQHD (2560x1440) signals are automatically upscaled to 4k (3840x2160) which results in a very sharp picture. So for games which are more demanding you can lower resolution to wqhd and still have very good results.
I thought it's time to open a topic about this projector and summarize all infos for people who are interested in buying it.
So far it's the only projector known to work in 1920x1080 @ 120hz and 3D Vision mode.
Update: Optoma recently introduced a new 1080p projector "Optoma HD27HDR" which also supports 1920x1080 @120hz in 3D mode. Please have a look at this topic for more information.
For using this projector with 3D Vision you additionally need this:
PC with Nvidia graphics card
3D Vision Emitter (it only servers as a license dongle. It's sold with the 3D Vision 2 Kit)
DLP glasses (see FAQ for recommendations which one to buy)
Step by step instructions how to make 3D work:
Connect one of the HDMI ports of the projector to the HDMI port of your graphics card.
Connect the 3D Vision emitter (pyramid) to your PC via USB cable
Turn on the projector and open Nvidia Control Panel (right click desktop / Nvidia Control Panel)
Go to "Set up multiple displays" and untick all devices except for "Optoma UHD"
Click on button "Apply". You should see your Windows desktop on the projector screen now
In Nvidia Control Panel click on "Set up Stereosopic 3D"
Tick option "Enable stereosopic 3D"
If 3D Vision isn't set up yet a setup wizard is automatically started. Choose 3D Vision there (not anaglyph) and complete the wizard. If it's already configured just make sure "Generic CRT" is selected from the list.
If the 3D Vision setzup wizard fails to be completed then look down at the section "Trouble Shooting"
Start a game
Make sure ingame resolution is set to 1920x1080 @120hz
On your remote control press the "3D" button to turn on 3D mode / DLP sync flash
Turn on your DLP glasses
If eyes are swapped then press CTRL + T several times until it's fixed. Alternatively you can toggle 3D on / off a few times with your remote control. Another more advanced option is to use 3dmigoto for reversing eyes. I don't recommend to use the Reverse 3D function of the projector itself as it's faulty. See section "How to fix swapped eyes in 3D mode" for more info on this topic
In the dialog window click on "Quick Setup" (this will skip the setup wizard and enable Stereoscopic 3D)
How to fix swapped eyes in 3D mode:
When starting a game in 3D mode you will often run into the trouble that sometimes 3D looks correct and other times when restarting the game you would have to wear your glasses upside down to see proper 3D. Is there are a trick to fix this issue permanently? Unfortunately the answer is no. Due to the nature of frame sequential 3D mode the projector can't know which frame belongs to which eye. So every time you start a game in 3D mode you will have a 50% chance that the eye order is correct.
How to correct wrong eye order:
There are several ways to fix wrong eye order. I will present all of them to you - so it's up to you which way you prefer.
Method 1 (my preferred way):
Press CTRL + T. This tells the Nvidia driver to disable 3D
Press CTRL + T again. 3D is re-enabled and with a chance of 50% the eye order is fixed now
Repeat step 1 and 2 until eye order is correct
For very rare games CTRL + T doesn't work (I think only Rise / Shadow of the Tomb Raider are affected). In this case try method 2 or 3 to fix eye order
Method 2:
Press button "3D" on your remote control and turn off 3D
Press the button again to re-enable 3D.
Repeat step 1 and 2 until eye order is correct
Method 3 (only available with DirectX 11 games):
Open 3D Fix Manager
Go to tab "Settings" and click on sub-tab "Display Profiles"
For the projector profile tick option "Link profile to display" and choose "Optoma UHD" from the list (when doing so the projector profile is automatically chosen when you play games on this device)
Tick option "Preferred 3D format" and choose "Regular 3D Vision (frame sequential)" from the list. This option also unlocks a Hotkey ingame for choosing different 3D formats. One of them is reversed frame sequential.
Go to tab "Installation" and in the left upper corner of the window change the default filter from "All Fix Types" to "3dmigoto". By doing so only DirectX 11 games are shown in the list
Select the game you want to play and click on button "Play 3D"
If eyes are swapped ingame press F11 once. Eye order is fixed 100% now
If you have accidentially pressed F11 too often just press it a few times more until you are back at the 3D format you want (F11 just cycles through 8 different 3D formats)
Note: Using this technique adds more latency and overhead. That's the reason I don't use it. But if you are fine with that extra latency you have a very easy and reliable method for fixing reversed eyes with just one single button press.
Method 4 (not recommended):
Press button "Menu" on your remote control
Go to sub-menu of "3D"
Select "3D sync invert" and set it to "On"
Note: Using the 3d sync invert feature of the projector itself can really cause headaches and introduce artefacts like a vertical tearing line. I highly recommend NOT to use this feature! In my opinion it's completely broken.
How to fix intermittent eye swapping in 3D mode:
In rare cases the projector starts swapping eyes in 3D mode every 10-15 seconds. This means that you would have to turn around the 3D glasses every few seconds which is unacceptable.
There is a simple fix for this:
Switch to the other HDMI channel. So if HDMI 2 is active just press "HDMI 1" on your remote control.
Switch back to HDMI 2 by pressing "HDMI 2" on your remote control
If HDMI 1 is your active HDMI port you have to do the reverse thing. The issue should be fixed then.
Correcting 3D depth:
When playing in stereo 3D mode you will probably notice that 3D depth is far too high even if you lower 3D separation to 50%. The reason for this is in the Nvidia driver which assumes that you play on a 17 inch CRT monitor in Generic CRT mode. So in other words the 3D depth is optimized for a very small display and this results in a 3D depth which is far too high. We can fix this by telling the driver that we actually play on a 100 inch (or taller) sized projector screen.
Go to tab "Settings" and click on sub-tab "Display Profiles"
For the projector profile tick the option "Screen size" and enter the size of your projector screen in inches
For the projector profile tick option "3D display type" and choose "3D Vision / 3DTV Play / Generic CRT" from the list
Tick option "Link profile to display" and choose "Optoma UHD" from the list (when doing so the projector profile is automatically chosen when you play games on this device)
When starting a game via 3D Fix Manager now you will notice that 3D depth doesn't hurt your eyes any more and is similar to your 3D Vision monitor (if you have one). If you are also playing on a monitor or TV you should repeat the steps described above accordingly for the monitor and TV profile. When not doing this 3D depth will be wrong for those devices.
Fixing washed out colors / image:
When using the projector with your PC the image might look a bit washed out and black levels aren't deep. The reason for this is that by default the Nvidia driver uses RGB color space with a limited range from 16-255. The projector however expects a RGB signal with a full range from 0-255. This dismatch makes the image look washed out.
Generally you can fix this issue either by adjusting color space in the OSD setting of the projector or by adjusting it in Nvidia Control Panel. In my opinion the best and most universal way is to leave the projector at its default setting for color space ( "Auto"). Instead we'll adjust color space in Nvidia Control. Please follow the tutorial:
Open Nvidia Control Panel (right click desktop / Nvidia Control Panel)
Go to "Change resolution"
Enable "Use Nvidia color settings" (by default this is set to "Use default color settings" which caps color range to 16-255)
Set "Output color format" to "YCbCr 444"
Click on "Apply" button
Press the "Menu" button on the remote control of your projector
Select "Image Settings"
Scroll down and select "Color Settings"
Make sure "Color Space" is set to "Auto" which is the factory default setting
Why use YCbCr 444?
YCbCr 444 is basically a converted RGB signal and offers the same quality as RGB. By using this you have the following advantages:
Washed out colors are reliably fixed for desktop, movies, games and HDR mode
Color saturation and tint can be set in the OSD settings of the projector (this is not available when using RGB mode)
You can leave the projector at its default value for color space ("Auto"). This would not work well if using RGB mode where you would have to set color space differently for HDR and non-HDR mode.
But it's up to you what you prefer. Another option would be to set RGB to full 0-255 range. But as said you would have to set color saturation globally in Nvidia Control Panel then (OSD option is locked). You can also set RGB to 16-255 in Nvidia Control Panel. But then you also have to set the same color range in the OSD setting of the projector! Both settings must match!
Fixing 3D issues on Windows 10:
When using Windows 10 you will run into some issues when you want to play games in 3D mode. A common issue is that some games don't start with 120 hz refresh rate which is required for 3D mode. Instead they are stuck at 60hz which you can notice by heavy flickering on the screen. Typically the Nvidia driver tries to force the required refresh rate ingame but this mechanism sometimes failes when using Windows 10. Windows 7 and 8.1 seem to be not affected by this issue.
In 99% of all cases these two steps will fix this issue:
Disable fullscreen optimizations (this is a feature which was introduced with Windows 10 v.1803). For doing things manually right click on the exe file of the game and choose "Properties". Then click on "Compatibility tab and tick option "Disable Fullscreen Optimizations"
Set desktop resolution to 1920x1080 @120hz before launching a game
So far, so good. But this is pretty uncomfortable to change desktop resolution from 4k to 1080p every time before launching a game. And after playing we have to set desktop resolution manually back to 4K. It's also troublsome to make sure that fullscreen optimizations are turned off for every single game.
Luckily we can automate this process on a global base for all games with 3D Fix Manager.
Here is what to do:
Open 3D Fix Manager
Go to tab "Settings" and click on sub-tab "Display Profiles"
For the projector profile tick option "Link profile to display" and choose "Optoma UHD" from the list (when doing so the projector profile is automatically chosen when you play games on this device)
Tick option "Desktop resolution 2D mode" and from the lists set 3840 x 2160 @60 resolution
Tick option "Desktop resolution 3D mode" and from the lists set 1920 x 1080 @120hz resolution
Look at the green text "Game settings for 3D mode" and below tick the option "Game resolution". Next to it set 1920 x 1080 @120hz resolution
Click on sub-tab "Nvidia 3D Settings"
Tick option "Auto disable Nvidia Stereoscopic 3D when closing games"
Click on sub-tab "Application Settings"
Tick option "Fullscreen optimizations" and from the list choose "Disable"
Start games via "Play 3D" button in tab "Installation"
After having configured 3D Fix Manager you will notice that desktop resolution is automatically set to 1920x1080 @120hz when launching a game. Also fullscreen optimizations are disabled in the properties of individual exe file of the game. Game should show 3D at 1920x1080 resolution which was set by 3D Fix Manager. After closing the game the desktop resolution is automatically set back to 3840x2160 @60hz (4K). Comfortable, isn't it?
How to enable Nvidia DSR for 3D mode:
DSR is the acronym for Dynamic Super Resolution. What it does is rendering the game internally in a higher resolution and scaling it down to the native resolution of the display. As a result we get a similar effect like Anti Aliasing but DSR is improving the whole picture quality while Anti Aliasing is only smoothing polygon edges. DSR is especially useful for games where no Anti Aliasing or just simple post processing mechanisms like FXAA is available.
The problem with DSR is that it always scales down to the native resolution of the display. Nvidia does not allow us to set an individual target resolution. For Optoma UHD 40 / 50 the native resolution is 3840 x 2160 but we need to scale the image down to 1920 x 1080 because higher resolutions do not support 120hz refresh rate which is required for 3D mode!
To force the driver to do a downscale to 1920x1080 we have to apply a modified EDID. An EDID contains all information about the display like the supported resolutions, refresh rates, manufacturer and so on. I've prepared a modified EDID where all 4k resolutions have been removed - by installing this EDID we can trick the Nvidia driver to think that we use a native full hd projector. DSR will downsample to 1920x1080 then.
Now you might think by applying this modfied EDID you are permanently downgrading your expensive 4K projector to a simple Full HD projector because all native 4k resolutions are gone. You are not completely wrong with your assumption! But remember that you have 2 HDMI ports on the projector. The EDID changes are only applied to one of them. If you connect the projector with 2 HDMI cables to your PC you can still use 4K resolutions by simply changing input signal to the other HDMI port where we still use the original 4K EDID! Problem solved! Of course you can revert changes anytime - nothing on the projector is changed. Only in Windows!
Please follow these steps to apply the EDID override for using DSR:
Download this file and unzip it. It contains a modified EDID for the projector where all resolutions higher than 1920x1080 have been removed
Connect your HDMI cable to "HDMI 1" port of your projector. By doing so we can still use the other port "HDMI 4K" for native 4K resolutions
Run "CRU.exe" and select "OTM0076 - Optoma UHD (active)" from the list in the top left corner
Click on button "Import" and select the "Optoma_UHD_40_DSR.inf" file you downloaded in step 1
Optional: Click on button "Edit" next to the list where you selected "OTM0076 - Optoma UHD (active)"
Optional: In the window "Display Properties" change the name from "Optoma UHD" to "Optoma 3D". This allows for better distinguishing between the two HDMI ports of the projector (otherwise both have the same name)
Close CRU by clicking on the "Ok" button
Restart your computer or run "restart.exe" (this restarts your display driver)
Open Nvidia Control Panel (right click desktop / Nvidia Control Panel)
Go to "Manage 3D Settings" and click on "Global Settings"
In the list click on "DSR - Factors" and tick factors "1.78" and "4.00". This will add 2560x1440 and 3840x2160 DSR resolutions
Set "DSR Smoothness" to "0%" for not losing any sharpness with DSR resolutions
Click on button "Apply"
For making sure DSR resolutions are listed in games reboot your system
In games you should be able to choose 4k and WQHD resolution in 2D/3D mode now
How to reset EDID changes:
Run "reset-all.exe" (it's located in the folder of CRU)
Restart your computer or run "restart.exe" (this restarts your display driver)
Setting up Stereoscopic Player for watching 3D movies without 3D Vision IR emitter:
The 3D Vision IR emitter is not necessarily required when you want to watch 3D movies. Stereoscopic Player enables us to watch movies without having the emitter connected to the PC. However you can only watch 3D movies from 3D DVDs and .MKV files from your HDD. Blurays don't work with this software. For watching 3D blurays you still need both the emitter as well as Power DVD 18 Ultra.
Please follow these steps to set up Stereoscopic Player to be used independently from the IR emitter:
Set the desktop resolution to 1920x1080 @120 Hz on your projector
Install "Stereoscopic Player 2.5" (The free version allows you to watch 3D movies up to 5 minutes. If you want to watch movies without any restrictions you can buy the software for 49€ in the online shop)
Start Stereoscopic Player
In the menu bar click on "View" -> go to "Viewing Method" and click on "Software Pageflipping" (this step has to be done on first start of the application only)
In the menu bar click on "File" -> "Open File..." and choose a .MKV file (= your 3D movie)
Now you are asked which 3D format is used by the movie. If you don't know what to choose just click on "OK". We can still change this later.
If you have chosen the wrong 3D format you either see two images side by side or one over the other now. If so go to "File" -> "Layout"
If the current movie shows two images side by side then choose "Side by Side, Left Image First". Otherwise if it shows one image over the other choose "Over/Under, Left Image Top". Now you should see only 1 image.
If your image looks stretched go to "File" -> "Aspect Ratio" and choose "Default, Half Width" if the 3D format is Side by Side. Otherwise choose "Default, Half Height"
Now double click on the video to enter fullscreen. You should be able to see a stereoscopic image
Turn on 3D via the remote control of your projector as well as your DLP glasses. You should see the movie in stereo 3D now
If eyes are swapped press F7 to correct this
You should keep in mind that Stereoscopic Player is not as user friendly as Power DVD. But at least you don't need the 3D Vision emitter then.
FAQ:
Is this projector called Optoma UHD 40 or Optoma UHD 50?
The projector is sold under different names depending on the country you live:
In Europe the projector is called Optoma UHD 40
In Northern America it's called Optoma UHD 50
Is this projector officially 3D Vision certified by Nvidia?
No. However when connecting the projector to the PC it's detected as a "Generic CRT" device which is exactly the same as 3D Vision! (just another name)
Do I need the 3D Vision IR emitter for 3D gaming?
Yes. The 3D Vision emitter (pyramid) serves as a license dongle for unlocking Generic CRT mode. It has no other purpose than that. Without Generic CRT mode the 3D Vision driver wouldn't allow us to ouput frame sequential 3D content to the projector. The Nvidia glasses included in the 3D Vision 2 Kit are not required. If you're lucky you'll find a cheap emitter sold separately on ebay. Otherwise you have to buy the complete 3D Vision 2 Kit (emitter + glasses).
Do I need the 3D Vision IR emitter for watching 3D movies?
This depends on the source of your 3D movie.
For watching 3D movies from your HDD (MKV file format) or 3D DVDs the 3D Vision emitter is not required. However this only works with "Stereoscopic Player". It's the only 3D video player which offers software page flipping which means that we don't need 3D Vision at all for outputting frame sequential 3D content to the projector. If you want to use this solution please follow the guide above to set up Stereoscopic Player.
Unfortunately Stereoscopic Player can't handle blurays. So for watching 3D blurays we still need the 3D Vision emitter as well as an alternative 3D video player capable of handling 3D blurays. I recommend "Cyberlink Power DVD 18 Ultra" which does this job very well.
Does Cyberlink Power DVD 18 Ultra work in 3D without the IR emitter?
No. Power DVD definitely requires the emitter for 3D movies.
Stereoscopic Player is the only 3D video player which is capable of playing 3D movies without the 3D Vision emitter. But it's limited to 3D DVDs and MKV-files. Blurays are generally not supported by this player.
Can I use my bluray player for watching 3D movies on Optoma UHD 40/50?
No. Bluray players use Framepacking 3D format which is not supported by Optoma UHD 40/50. You would need a bluray player capable of frame sequential format. Maybe some older bluray players or the Playstation 3 still support this.
Do I need additional hardware / software for watching 3D blurays on Optoma UHD 40 / 50
Yes. For watching 3D blurays you need an internal bluray drive for your PC. I generally recommend bluray drives by LG Electronics. They only cost 50-60€, are fast, very silent and can also burn blurays / DVDs / CDs.
Of course you can also watch 3D movies from .MKV files on your HDD.
Second you need the 3D Vision emitter. As said before it's only a license dongle but without it the 3D Vision driver won't allow to output frame sequential 3D content to the pojector.
Last but not least you need a 3D video player. I recommend "Cyberlink Power DVD 18 Ultra" which is the best player for stereo 3D movies in my opinion.
If you just want to watch 3D movies from .MKV files on your HDD you can alternatively use "Stereoscopic Player" which is also a very good player. This player however does NOT support 3D bluray disks.
Does this projector work with 3D Vision glasses?
For me 3D Vision glasses didn't sync properly with this projector. That means periodically every 5 seconds you see a lot of ghosting with 3D Vision glasses or you just have a constant ghosting.
However another user reported that his Optoma UHD 40 worked perfectly with the 3D Vision glasses. So far it's unclear why it worked for him but not for me. Either way it's worth trying the glasses - if they work reliably for you I would recommend to take them instead of DLP glasses as they have the best quality in my opinion. If 3D Vision glasses don't work then just use DLP glasses. See recommendations below which to buy.
Is Nvidia 3DTV Play supported?
No because the projector does not support 3D framepacking.
Is Top & Bottom or Side By Side 3D format supported?
No. Frame sequential is the only 3D format supported by the projector.
Optoma does not list 1920x1080 @120hz resolution in their manual. Is this resolution really supported?
Yes. 1920x1080 @120hz is definitely supported. Optoma probably simply forgot to list the resolution in the manual.
Is downsampling via Nvidia DSR supported?
Yes. However you have to apply a modified EDID first. See the guide which is located above the FAQ.
Is the projector bright enough for 3D gaming?
Compared to a Lightboost monitor brightness is a bit lower (maybe 30% lower on a white 1.0 gain screen). It really depends on the screen which is used. I think with a 1.5 gain screen or higher brightness can reach the level of a lightboost monitor. It's pretty hard to compare because you can increase brightness on a monitor very strongly but then you have ghosting all over the place. If you want 0 ghosting you would have to make your monitor darker than the projector in some cases. But overall I would say the projector is less bright than a monitor in stereo 3D mode.
I have a 90 inch white diffuse 1.2 gain screen which boosts brightness a bit and in my opinion brightness is pretty good. I can play dark games like Dead Space 2 and Outlast without any issues. You should use "Dynamic Black" mode for significantly increasing brightness in 3D mode. But as said before I think a 1.5 gain screen would be perfect for 3D gaming. Brightness should reach similar levels like monitors then.
How is input lag for gaming?
When playing in 120hz resolution input lag is brilliant. For HDR 4k @60hz input lag is still on a very good level as long as you don't enable Vertical Sync! I suggest to use Scanline Sync of RivaTuner Staistics Server which is similar to Vsync on but without the additional input lag.
The projector has 2 HDMI ports. Are they both compatible to 3D?
Yes, both ports support 3D in 1920x1080 @120hz. However they differ in bandwith capacity. The "4k HDMI" port supports up to 4k @60hz and the "HDMI 1" port only up to 4k @30hz.
If you need a longer cable you probably have to use an active HDMI repeater. I recommend this HDMI repeater.
Which DLP glasses are recommended?
DLP glasses vary in quality, maximum brightness and whether they are able to successfully suppress crosstalk / ghosting.
Here are my recommendations / charts. For rating I gave school grades (1,0 is best and 6,0 worst). Keep in mind that you might not find each of the listed DLP glasses in your country (the list is related to German / European online shops).
The Andoer G15 are the only DLP glasses on the market which are absolutely ghosting free. Even in high contrast scenarios you will never see any ghosting. But the quality of the frame is very poor and glasses are very small. Mine broke after a few months (I cannot attach the temples any more). You need to insert separate coin batteries (not rechargeable).
The Xpand Edux 3 X103 look similar to the 3D Vision glasses however they are not as comfortable as those. The very good ghosting quality comes at the cost of a lower brightness. You need to insert separate coin batteries (not rechargeable).
Optoma ZD302 (55€) -> same crap as Hi-SHOCK® DLP Pro 7G (lot of ghosting visible)
Xpand-X105 (66€) -> Poor contrast, very "milky" when looking through glasses, however great brightness and very low ghosting. This glasses are very uncomfortable without modding with nose pads. Lower frame is transparent which is a bit disturbing. Overall I wouldn't recommend it although ghosting is very low.
Is this projector true, native 4K?
No. Although it's advertised as a 4k projector it's not native 4k. It has a Full HD DMD chip and a 4x pixel shifter. This means that four Full HD pictures are sequentially projected to the screen which results in a combined 4K image. The shifting happens so fast that our eyes see this as one single 4K image.
What about the noise level of the projector?
According to the data sheet the projector has a noise level of 25 dB which is lower than most other projectors. In my opinion this is one of the most silent DLP projectors currently available on the market. You can hear some silent buzzing due to the pixel shifting in 60hz mode which completely vanishes when you change to 120hz input signal / play in 3D.
Does this projector show rainbow color artifacts?
In my opinion rainbow artifacts are very rarely visible as this projector has a RGBRGB wheel. This wheel tends to have much less rainbow artefacts than RGBCYW wheels. Of course it also depends on the individual person if he / she is sensitive to those artefacts but I am very happy with it.
Does the projector support upscaling?
Yes. For 2D mode WQHD (2560x1440) signals are automatically upscaled to 4k (3840x2160) which results in a very sharp picture. So for games which are more demanding you can lower resolution to wqhd and still have very good results.

Coming from a w1070 myself, I can say that a new bulb made a big difference in brightness. You don't notice it dim gradually, but you notice the difference between an end of life bulb and a brand new one. That said, it's been 10 months between using the Benq w1070 and this UHD51A (same lumens as the UHD50)...so I don't know that I could accurately compare the two.

Brightness is pretty good in my opinion for Optoma UHD 40. Of course it also depends on the screen. But with a default white 1.0 gain screen you shouldn't be disappointed. But I would strongly recommend a 1.5 gain screen or higher. Unfortunately I have 1.2 screen. A bit more brightness would not harm. Btw I've added your question to the FAQ.

Great post Paul and a real asset to the community. I think you've established a very useful template that we can build on.
For 3d vision purposes it's out of scope, but is it worth linking to any technical info like throw calculators, or to any independent 3rd party reviews (if there are any)?
Since this projector is 'only' frame sequential, others might not be aware but a few years ago there were boxes such as the Optoma 3dxl converter, which accept frame packed 3d and convert to frame sequential 3d. I believe they are limited to 720p input though.

There was another one with very similar specs, but I can't for the life of me remember who made it and what it was called.

[quote="jhgator1777"]would this projector be an upgrade if I already have an LG 4k3d tv?[/quote]
To be fair, when you say upgrade, in what aspect? Apart from the fact that this will give you a massive 3d screen, it will probably be dimmer than your TV. Also, it depends on what model TV it is.

Ok, so the OLED 6 series are pretty much if not the best passive 3d tv's ever made.
In fact, you can use 3dmigoto upscaler to feed it a native 4k interlaced signal which might even have a higher effective resolution than 1920x1080x120 frame sequential that this projector offers.
This projector will give you native 3d vision on a massive screen, but will probably be dimmer and have higher input lag than your tv. I think the 6 series are approx 20ms input lag.
Also, it's active v passive, but that's another debate.

Great information PaulDusler.
Mutch easier then digging true the AVS forums to find the info lol
Still very happy with this projector.
So it seems the Uhd51 won`t do Full 3d?
So far it's the only projector known to work in 1920x1080 @ 120hz and 3D Vision mode.
Update: Optoma recently introduced a new 1080p projector "Optoma HD27HDR" which also supports 1920x1080 @120hz in 3D mode. Please have a look at this topic for more information.

Trouble Shooting:
3D Vision setup wizard fails / can't be completed
If this happens do the following steps:
How to fix swapped eyes in 3D mode:
When starting a game in 3D mode you will often run into the trouble that sometimes 3D looks correct and other times when restarting the game you would have to wear your glasses upside down to see proper 3D. Is there are a trick to fix this issue permanently? Unfortunately the answer is no. Due to the nature of frame sequential 3D mode the projector can't know which frame belongs to which eye. So every time you start a game in 3D mode you will have a 50% chance that the eye order is correct.
How to correct wrong eye order:
There are several ways to fix wrong eye order. I will present all of them to you - so it's up to you which way you prefer.
Method 1 (my preferred way):
Method 2:
Method 3 (only available with DirectX 11 games):
Note: Using this technique adds more latency and overhead. That's the reason I don't use it. But if you are fine with that extra latency you have a very easy and reliable method for fixing reversed eyes with just one single button press.
Method 4 (not recommended):
Note: Using the 3d sync invert feature of the projector itself can really cause headaches and introduce artefacts like a vertical tearing line. I highly recommend NOT to use this feature! In my opinion it's completely broken.
How to fix intermittent eye swapping in 3D mode:
In rare cases the projector starts swapping eyes in 3D mode every 10-15 seconds. This means that you would have to turn around the 3D glasses every few seconds which is unacceptable.
There is a simple fix for this:
If HDMI 1 is your active HDMI port you have to do the reverse thing. The issue should be fixed then.
Correcting 3D depth:
When playing in stereo 3D mode you will probably notice that 3D depth is far too high even if you lower 3D separation to 50%. The reason for this is in the Nvidia driver which assumes that you play on a 17 inch CRT monitor in Generic CRT mode. So in other words the 3D depth is optimized for a very small display and this results in a 3D depth which is far too high. We can fix this by telling the driver that we actually play on a 100 inch (or taller) sized projector screen.
Please follow these steps to correct 3D depth:
When starting a game via 3D Fix Manager now you will notice that 3D depth doesn't hurt your eyes any more and is similar to your 3D Vision monitor (if you have one). If you are also playing on a monitor or TV you should repeat the steps described above accordingly for the monitor and TV profile. When not doing this 3D depth will be wrong for those devices.
Fixing washed out colors / image:
When using the projector with your PC the image might look a bit washed out and black levels aren't deep. The reason for this is that by default the Nvidia driver uses RGB color space with a limited range from 16-255. The projector however expects a RGB signal with a full range from 0-255. This dismatch makes the image look washed out.
Generally you can fix this issue either by adjusting color space in the OSD setting of the projector or by adjusting it in Nvidia Control Panel. In my opinion the best and most universal way is to leave the projector at its default setting for color space ( "Auto"). Instead we'll adjust color space in Nvidia Control. Please follow the tutorial:
Why use YCbCr 444?
YCbCr 444 is basically a converted RGB signal and offers the same quality as RGB. By using this you have the following advantages:
But it's up to you what you prefer. Another option would be to set RGB to full 0-255 range. But as said you would have to set color saturation globally in Nvidia Control Panel then (OSD option is locked). You can also set RGB to 16-255 in Nvidia Control Panel. But then you also have to set the same color range in the OSD setting of the projector! Both settings must match!
Fixing 3D issues on Windows 10:
When using Windows 10 you will run into some issues when you want to play games in 3D mode. A common issue is that some games don't start with 120 hz refresh rate which is required for 3D mode. Instead they are stuck at 60hz which you can notice by heavy flickering on the screen. Typically the Nvidia driver tries to force the required refresh rate ingame but this mechanism sometimes failes when using Windows 10. Windows 7 and 8.1 seem to be not affected by this issue.
In 99% of all cases these two steps will fix this issue:
So far, so good. But this is pretty uncomfortable to change desktop resolution from 4k to 1080p every time before launching a game. And after playing we have to set desktop resolution manually back to 4K. It's also troublsome to make sure that fullscreen optimizations are turned off for every single game.
Luckily we can automate this process on a global base for all games with 3D Fix Manager.
Here is what to do:
After having configured 3D Fix Manager you will notice that desktop resolution is automatically set to 1920x1080 @120hz when launching a game. Also fullscreen optimizations are disabled in the properties of individual exe file of the game. Game should show 3D at 1920x1080 resolution which was set by 3D Fix Manager. After closing the game the desktop resolution is automatically set back to 3840x2160 @60hz (4K). Comfortable, isn't it?
How to enable Nvidia DSR for 3D mode:
DSR is the acronym for Dynamic Super Resolution. What it does is rendering the game internally in a higher resolution and scaling it down to the native resolution of the display. As a result we get a similar effect like Anti Aliasing but DSR is improving the whole picture quality while Anti Aliasing is only smoothing polygon edges. DSR is especially useful for games where no Anti Aliasing or just simple post processing mechanisms like FXAA is available.
The problem with DSR is that it always scales down to the native resolution of the display. Nvidia does not allow us to set an individual target resolution. For Optoma UHD 40 / 50 the native resolution is 3840 x 2160 but we need to scale the image down to 1920 x 1080 because higher resolutions do not support 120hz refresh rate which is required for 3D mode!
To force the driver to do a downscale to 1920x1080 we have to apply a modified EDID. An EDID contains all information about the display like the supported resolutions, refresh rates, manufacturer and so on. I've prepared a modified EDID where all 4k resolutions have been removed - by installing this EDID we can trick the Nvidia driver to think that we use a native full hd projector. DSR will downsample to 1920x1080 then.
Now you might think by applying this modfied EDID you are permanently downgrading your expensive 4K projector to a simple Full HD projector because all native 4k resolutions are gone. You are not completely wrong with your assumption! But remember that you have 2 HDMI ports on the projector. The EDID changes are only applied to one of them. If you connect the projector with 2 HDMI cables to your PC you can still use 4K resolutions by simply changing input signal to the other HDMI port where we still use the original 4K EDID! Problem solved! Of course you can revert changes anytime - nothing on the projector is changed. Only in Windows!
Please follow these steps to apply the EDID override for using DSR:
How to reset EDID changes:
Setting up Stereoscopic Player for watching 3D movies without 3D Vision IR emitter:
The 3D Vision IR emitter is not necessarily required when you want to watch 3D movies. Stereoscopic Player enables us to watch movies without having the emitter connected to the PC. However you can only watch 3D movies from 3D DVDs and .MKV files from your HDD. Blurays don't work with this software. For watching 3D blurays you still need both the emitter as well as Power DVD 18 Ultra.
Please follow these steps to set up Stereoscopic Player to be used independently from the IR emitter:
You should keep in mind that Stereoscopic Player is not as user friendly as Power DVD. But at least you don't need the 3D Vision emitter then.
FAQ:
Is this projector called Optoma UHD 40 or Optoma UHD 50?
The projector is sold under different names depending on the country you live:
Is this projector officially 3D Vision certified by Nvidia?
No. However when connecting the projector to the PC it's detected as a "Generic CRT" device which is exactly the same as 3D Vision! (just another name)
Do I need the 3D Vision IR emitter for 3D gaming?
Yes. The 3D Vision emitter (pyramid) serves as a license dongle for unlocking Generic CRT mode. It has no other purpose than that. Without Generic CRT mode the 3D Vision driver wouldn't allow us to ouput frame sequential 3D content to the projector. The Nvidia glasses included in the 3D Vision 2 Kit are not required. If you're lucky you'll find a cheap emitter sold separately on ebay. Otherwise you have to buy the complete 3D Vision 2 Kit (emitter + glasses).
Do I need the 3D Vision IR emitter for watching 3D movies?
This depends on the source of your 3D movie.
For watching 3D movies from your HDD (MKV file format) or 3D DVDs the 3D Vision emitter is not required. However this only works with "Stereoscopic Player". It's the only 3D video player which offers software page flipping which means that we don't need 3D Vision at all for outputting frame sequential 3D content to the projector. If you want to use this solution please follow the guide above to set up Stereoscopic Player.
Unfortunately Stereoscopic Player can't handle blurays. So for watching 3D blurays we still need the 3D Vision emitter as well as an alternative 3D video player capable of handling 3D blurays. I recommend "Cyberlink Power DVD 18 Ultra" which does this job very well.
Does Cyberlink Power DVD 18 Ultra work in 3D without the IR emitter?
No. Power DVD definitely requires the emitter for 3D movies.
Stereoscopic Player is the only 3D video player which is capable of playing 3D movies without the 3D Vision emitter. But it's limited to 3D DVDs and MKV-files. Blurays are generally not supported by this player.
Can I use my bluray player for watching 3D movies on Optoma UHD 40/50?
No. Bluray players use Framepacking 3D format which is not supported by Optoma UHD 40/50. You would need a bluray player capable of frame sequential format. Maybe some older bluray players or the Playstation 3 still support this.
Do I need additional hardware / software for watching 3D blurays on Optoma UHD 40 / 50
Yes. For watching 3D blurays you need an internal bluray drive for your PC. I generally recommend bluray drives by LG Electronics. They only cost 50-60€, are fast, very silent and can also burn blurays / DVDs / CDs.
Of course you can also watch 3D movies from .MKV files on your HDD.
Second you need the 3D Vision emitter. As said before it's only a license dongle but without it the 3D Vision driver won't allow to output frame sequential 3D content to the pojector.
Last but not least you need a 3D video player. I recommend "Cyberlink Power DVD 18 Ultra" which is the best player for stereo 3D movies in my opinion.
If you just want to watch 3D movies from .MKV files on your HDD you can alternatively use "Stereoscopic Player" which is also a very good player. This player however does NOT support 3D bluray disks.
Does this projector work with 3D Vision glasses?
For me 3D Vision glasses didn't sync properly with this projector. That means periodically every 5 seconds you see a lot of ghosting with 3D Vision glasses or you just have a constant ghosting.
However another user reported that his Optoma UHD 40 worked perfectly with the 3D Vision glasses. So far it's unclear why it worked for him but not for me. Either way it's worth trying the glasses - if they work reliably for you I would recommend to take them instead of DLP glasses as they have the best quality in my opinion. If 3D Vision glasses don't work then just use DLP glasses. See recommendations below which to buy.
Is Nvidia 3DTV Play supported?
No because the projector does not support 3D framepacking.
Is Top & Bottom or Side By Side 3D format supported?
No. Frame sequential is the only 3D format supported by the projector.
Optoma does not list 1920x1080 @120hz resolution in their manual. Is this resolution really supported?
Yes. 1920x1080 @120hz is definitely supported. Optoma probably simply forgot to list the resolution in the manual.
Is downsampling via Nvidia DSR supported?
Yes. However you have to apply a modified EDID first. See the guide which is located above the FAQ.
Is the projector bright enough for 3D gaming?
Compared to a Lightboost monitor brightness is a bit lower (maybe 30% lower on a white 1.0 gain screen). It really depends on the screen which is used. I think with a 1.5 gain screen or higher brightness can reach the level of a lightboost monitor. It's pretty hard to compare because you can increase brightness on a monitor very strongly but then you have ghosting all over the place. If you want 0 ghosting you would have to make your monitor darker than the projector in some cases. But overall I would say the projector is less bright than a monitor in stereo 3D mode.
I have a 90 inch white diffuse 1.2 gain screen which boosts brightness a bit and in my opinion brightness is pretty good. I can play dark games like Dead Space 2 and Outlast without any issues. You should use "Dynamic Black" mode for significantly increasing brightness in 3D mode. But as said before I think a 1.5 gain screen would be perfect for 3D gaming. Brightness should reach similar levels like monitors then.
How is input lag for gaming?
When playing in 120hz resolution input lag is brilliant. For HDR 4k @60hz input lag is still on a very good level as long as you don't enable Vertical Sync! I suggest to use Scanline Sync of RivaTuner Staistics Server which is similar to Vsync on but without the additional input lag.
The projector has 2 HDMI ports. Are they both compatible to 3D?
Yes, both ports support 3D in 1920x1080 @120hz. However they differ in bandwith capacity. The "4k HDMI" port supports up to 4k @60hz and the "HDMI 1" port only up to 4k @30hz.
Which HDMI cable should I use?
If you need a longer cable you probably have to use an active HDMI repeater. I recommend this HDMI repeater.
Which DLP glasses are recommended?
DLP glasses vary in quality, maximum brightness and whether they are able to successfully suppress crosstalk / ghosting.
Here are my recommendations / charts. For rating I gave school grades (1,0 is best and 6,0 worst). Keep in mind that you might not find each of the listed DLP glasses in your country (the list is related to German / European online shops).
Brightness: 1,0
Colors: 1,0
Ghosting: 1,0
Contrast: 1,0
Comfort: 4,0
Build Quality: 6,0
The Andoer G15 are the only DLP glasses on the market which are absolutely ghosting free. Even in high contrast scenarios you will never see any ghosting. But the quality of the frame is very poor and glasses are very small. Mine broke after a few months (I cannot attach the temples any more). You need to insert separate coin batteries (not rechargeable).
Brightness: 2,0
Colors: 2,0 (cool colors)
Ghosting: 2,0
Contrast: 1,5
Comfort: 2,5
Build Quality: 2,0
The Cinemax Wave Xtra series are good glasses but brightness is a bit lower and colors are not as vibrant as the Andoer G15 glasses.
Brightness: 2,0
Colors: 2,0 (cool colors)
Ghosting: 2,5
Contrast: 2,0
Comfort: 3,0
Build Quality: 2,5
The Apeman has a bit more ghosting than the Wave Xtra Series but it has a practical button for reversing eyes
Brightness: 2,5
Colors: 2,5 (very cool, blueish colors)
Ghosting: 1,5
Contrast: 2,0
Comfort: 3,5
Build Quality: 1,5
The Xpand Edux 3 X103 look similar to the 3D Vision glasses however they are not as comfortable as those. The very good ghosting quality comes at the cost of a lower brightness. You need to insert separate coin batteries (not rechargeable).
DLP glasses not recommended:
Is this projector true, native 4K?
No. Although it's advertised as a 4k projector it's not native 4k. It has a Full HD DMD chip and a 4x pixel shifter. This means that four Full HD pictures are sequentially projected to the screen which results in a combined 4K image. The shifting happens so fast that our eyes see this as one single 4K image.
What about the noise level of the projector?
According to the data sheet the projector has a noise level of 25 dB which is lower than most other projectors. In my opinion this is one of the most silent DLP projectors currently available on the market. You can hear some silent buzzing due to the pixel shifting in 60hz mode which completely vanishes when you change to 120hz input signal / play in 3D.
Does this projector show rainbow color artifacts?
In my opinion rainbow artifacts are very rarely visible as this projector has a RGBRGB wheel. This wheel tends to have much less rainbow artefacts than RGBCYW wheels. Of course it also depends on the individual person if he / she is sensitive to those artefacts but I am very happy with it.
Does the projector support upscaling?
Yes. For 2D mode WQHD (2560x1440) signals are automatically upscaled to 4k (3840x2160) which results in a very sharp picture. So for games which are more demanding you can lower resolution to wqhd and still have very good results.

one question: how's the brightness while gaming at 1080px120hz, compared to your lightboost monitor ? as a point of reference, i have bq w1070 and it's 3d images under glasses (dlp and nvdia) are way darker than my lightboost benq monitor, almost not usable, i have to pump up brightness and contrast to the detriment of black level.

Brightness is pretty good in my opinion for Optoma UHD 40. Of course it also depends on the screen. But with a default white 1.0 gain screen you shouldn't be disappointed. But I would strongly recommend a 1.5 gain screen or higher. Unfortunately I have 1.2 screen. A bit more brightness would not harm. Btw I've added your question to the FAQ.

Could you also mention your screen size? Its really important for brightness question
For 3d vision purposes it's out of scope, but is it worth linking to any technical info like throw calculators, or to any independent 3rd party reviews (if there are any)?
Since this projector is 'only' frame sequential, others might not be aware but a few years ago there were boxes such as the Optoma 3dxl converter, which accept frame packed 3d and convert to frame sequential 3d. I believe they are limited to 720p input though.

There was another one with very similar specs, but I can't for the life of me remember who made it and what it was called.

To be fair, when you say upgrade, in what aspect? Apart from the fact that this will give you a massive 3d screen, it will probably be dimmer than your TV. Also, it depends on what model TV it is.

In fact, you can use 3dmigoto upscaler to feed it a native 4k interlaced signal which might even have a higher effective resolution than 1920x1080x120 frame sequential that this projector offers.
This projector will give you native 3d vision on a massive screen, but will probably be dimmer and have higher input lag than your tv. I think the 6 series are approx 20ms input lag.
Also, it's active v passive, but that's another debate.

Someone tried to make BenQ W1700 work in 3D but he failed. I think for W2700 the issue will be similar. But maybe someone can get it working.
Btw I've finished the FAQ and guides so far now.

Mutch easier then digging true the AVS forums to find the info lol
Still very happy with this projector.
So it seems the Uhd51 won`t do Full 3d?
