The Ultimate Nvidia 3D Vision DLP Display
  1 / 9    
Greetings fellow Nvidia 3D Vision enthusiasts! I've been following(lurking) these forums for quite some time, trying to keep up to date on advancements in 3D Vision Ready titles, as well as Helix Mod fixes and other amazing shader hacking fixes to games that are simply breathtaking in stereoscopic 3D. I am incredibly saddened by the news of the demise of Nvidia 3D vision driver support in 2020. With this bad news weighing down the 3D vision community, I thought you could all use some good news on the 3D vision display front This is just a PSA to let you all know that I have finally, after years of searching, found the holy grail of DLP projection that we have all been waiting for. The projector that I am speaking of is the Optoma HD27HDR. The launch specifications of this projector in Q4 of 2018 indicated that it was locked to 1080p 60hz whilst also touting an HDMI 2.0 port and a second 1.4 port on the back. A total waste of bandwidth with these limits in place if you ask me. After some internet outcry from the AVSforum community, the projector has since been patched to support 1080p at 120hz! Now this patch doesn't exactly mean the projector is Nvidia 3d Vision Ready. This is where some nifty EDID manipulation changes the game entirely. Using CRU, the Custom Resolution Utility made by ToastyX, it is possible to make your Nvidia driver believe that your HD27HDR is a 3D Vision Ready Optoma Projector!!! This works with any Nvidia 3D Vision 2 glasses that you already own! There is no need for DLP Link glasses like you need with the Optoma UHD40/UHD50! Starting out with the projector menus, you want to ensure that 3d mode is enabled and that it is set to IR instead of DLP Link. Also you will want to set the 3D mode in the projectors 3D menu to Frame Sequential. You may also need to play with the 3D Sync Invert option, as the projector can lose sync with your game when Alt+Tabbing between game and desktop. I've found that using the VESA sync cable that you got in your Nvidia 3D vision kit keeps the projector from desyncing when Alt+Tabbing(Never thought you'd have any use for that cable, huh?). If you are missing that cable, or you run into the rare desync, there is a Re-Sync button on the projector remote and the projector itself. Within CRU you will want to edit the Product ID from OTM1727 to OTM3032 and after you use the Restart/Restart64 executables the Nvidia driver will recognize the projector as Nvidia 3D Vision Ready. If anything goes wrong with your CRU editing, you can use the Reset All executable and start from scratch. Also, when you open up the CRU executable you will want to delete all resolutions above 1080p 120hz so you can experience some glorious DSR enabled 3D vision as well. That is another part of this projector I forgot to mention. The projector has a built in DSR-esque function, in that it can take 4K60 input from a PC or a console and display it in 1080p. If you want 4K at 120hz however, you will want to use Nvidia DSR from within the Nvidia Control Panel and have your 4k resolution beamed out at 1080p 120hz. Thank you for being an awesome community for all of these years of 3D vision support. Enjoy the immersion of 1080p 120hz 3D projection!

wow, thank you for the info, the price is pretty low, do you own it ? are you using nvidia glasses ?

That's quite a surprise to me, but in a good way. It used to be available on certified 3d vision projectors, partly so that could disable the DLP sync flash and still trigger 3d mode.I know some older Optoma projectors had a separate 3d module, but I thought it was RF rather than IR. It's been a while though! Cna I ask, when you change the ID to OTM3032, what does it show up as in the Nvidia control panel?

Thanks for posting and confirming that this works at 1080P@120. rustyk21 brought this PJ to my attention when he mentioned a post on BlurBusters about it. It wasn't until Kaine did his review on it, that it seemed likely to work with 3D Vision. A PJ like this is so long over due, it saddens me. With any luck, manufacturers might start actually start listening to their buyers. Anyhow, what firmware version is installed on it and is this the US model?

@TanookiPhoenix: Awesome news! At least we got 2 projectors running in 1080p@120hz + 3D Vision now! Maybe worth doing [url=https://forums.geforce.com/default/topic/1079987/3d-vision/optoma-uhd-40-50-3d-vision-projector-1920x1080-120hz-/1/]another FAQ[/url] like I did? It doesn't have to be that complex. Just the most important things like: "Is this projector called [b][color="orange"]Optoma HD27 HDR[/color][/b] or [b][color="orange"]Optoma HD27H[/color][/b] or [b][color="orange"]Optoma HD29H?[/color][/b]" Just because Optoma has a confusing strategy to name their projectors differently depending on the country you live. You won't find a "Optoma HD27 HDR" projector in Germany but we have exactly the same projector called "Optoma HD29H" lol. While in Asia the suffix "HDR" was shortened to "H". Another thing interesting is that Optoma HD27 HDR has more light power while the color wheel is RYGCWB. I think I've never seen such a color wheel yet?! Not sure - but probably produces more RBE. Would be interesting to hear your feedback about this!

[quote="mistersvin21"]wow, thank you for the info, the price is pretty low, do you own it ? are you using nvidia glasses ?[/quote] I do currently own this projector and I am indeed using the Nvidia 3D Vision 2 glasses. There were a few pieces of information that I needed to add last night though. The projector is very low latency at most times(3D mode included) with about a 16ms input delay at 60hz with enhanced gaming mode selected, which is about 1 or 2ms more than my current ASUS PG278QR G-Sync monitor, so it is very snappy. The amazing news is that it can reduce to 8.3ms input lag at 120hz in 2D mode when enhanced gaming mode is ticked, which is as low as a CRT display!!! Now on to the slightly less positive news. When using Nvidia 3D vision in fullscreen mode there is an error message that says it is using an unsupported resolution at 1080p 120hz. This problem is easily defeated thanks to the work of Helifax and the 3D Fix Manager downloadable through the Helix Mod blog. There is an option within the 3D Fix Manager to disable on screen display messages like the one reporting the resolution error. The only downside to this approach is that you lose the depth slider OSD. This is only a slight annoyance but if you ever tinker with convergence settings then this should be no problem, as convergence has no OSD. Also, when you get Nvidia 3D Vision working with the glasses, you might notice a slight green crosstalk anomaly that is easily fixed by a combination of lowering the contrast a few ticks in combination with turning down the green gain a bit within the projector menus. I followed a calibration guide and added the lowered contrast and green gain along with it to find a suitable image that is still much brighter and clearer than my previous projector, the Viewsonic PJD6531w.

I tried the EDID of several Optoma projectors and found that this one had the least problems with desync and some jarringly broken 3D effects. User John105 has a Geforce Forum post called "List of 3D Vision Ready Hardware" that I referenced to try out the 4 different Optoma DLP EDIDs that exist. The list is in XLSX or CSV format. you can try them all to see what I mean.

Rainbow effect is easily overlooked on this projector model. My PJD6531w had a moderate amount of rainbow effect but this projector has significantly less. I honestly barely ever notice the RBE on this projector.

I have the same spreadsheet downloaded to my pc, as I used it to try different IDs when trying to get my tk800 to work. I'll try this Id as well as I have nothing to lose :-)

Starting out with the projector menus, you want to ensure that 3d mode is enabled and that it is set to IR instead of DLP Link. Also you will want to set the 3D mode in the projectors 3D menu to Frame Sequential. You may also need to play with the 3D Sync Invert option, as the projector can lose sync with your game when Alt+Tabbing between game and desktop. I've found that using the VESA sync cable that you got in your Nvidia 3D vision kit keeps the projector from desyncing when Alt+Tabbing(Never thought you'd have any use for that cable, huh?). If you are missing that cable, or you run into the rare desync, there is a Re-Sync button on the projector remote and the projector itself.

Within CRU you will want to edit the Product ID from OTM1727 to OTM3032 and after you use the Restart/Restart64 executables the Nvidia driver will recognize the projector as Nvidia 3D Vision Ready.


Thanks for the info. I always wondered if this projector could be cheaper alternative to the UHD40/50 etc.

To be clear, you're saying it has an IR 3d mode? That's quite a surprise to me, but in a good way. It used to be available on certified 3d vision projectors, partly so that could disable the DLP sync flash and still trigger 3d mode.I know some older Optoma projectors had a separate 3d module, but I thought it was RF rather than IR. It's been a while though!

Cna I ask, when you change the ID to OTM3032, what does it show up as in the Nvidia control panel?



When you switch the EDID over to OTM3032 it is listed in the Nvidia Control Panel as an "Nvidia 3D Vision Ready Projector" and it doesn't list any specific model number. I tried the EDID of several Optoma projectors and found that this one had the least problems with desync and some jarringly broken 3D effects.

[quote="jhgator1777"]Does this projector have something similar to lightboost or ulmb when 3d is activated?[/quote] For DLP projectors, there is no value or need to have ULMB or LightBoost, because DLP technology already has that built in implicitly. The micro mirrors that create the image can switch in [i]microseconds[/i], not milliseconds, so for all practical purposes it's instantaneous. LightBoost is a way to flash an LCD backlight to strobe the light to sometimes make it brighter, but more importantly, to limit the time that it is on, so that you don't see ghosting in 3D. For DLP micromirrors, when they are off, they are fully off, there is no bleed, and the timing is so fast that there is no need for a flash. This is why DLP projectors have zero ghosting. So projectors always run at full brightness, because there is no need to limit the brightness in 3d. The dimming you get in 3D is because you lose half the light because one eye is blocked each frame. There is no way to make it brighter with DLP unless you use a brighter lamp. There is no need for ULMB, because if it's running at 120Hz, you are automatically getting zero motion blur, because of how fast the micromirrors transition. Any DLP projector is far superior for motion blur than even the best ULMB monitor.
