You won't be always able to use native resolution because of GPU power. So upscalling is important.
I understood also that 850 has less CPU power than 950.

so when I will not use the native resolution of the TV, and I will use 1920x1080 for example, it means that I will have to rely compulsorily computing power of the CPU upscaling of TV? increase the input lag, and then it's up to cpu tv reduce input lag.
is that what you meant?

I don't know if Inputlag will be higher(according to the tests should be the same) but the TV might be slower.
Upscalling relies on some algorithms to improve image quality. LG advertised them to be different.

I just updated my 3D display from an active 50" Samsung 3D plasma HDTV to a passive 65" LG 3D display [b]LG65UG8709 (LG65UG870V)[/b]. This was an experiment because I could not find accurate answers to my burning 3D questions (neither online nor in shops). Of course I would have loved to go OLED but the current prices for 65" are far out of my budget (and will probably be for a few years to come), so I took the LED-LCD model.
Now I can answer the questins first hand myself. I hope it will be useful for others still in the decision-making phase regarding a new 3D display.
[i]- Which 3D resolutions can be used with nVidia 3DTV Play?[/i]
At least 720p @ 60Hz and 1080p @ 24Hz frame packing. The LG detects this 3D formats automatically and switches to 3D mode.
I also have a "HDMI-Checkerboard" option offered by 3DTV Play when using no EDID override. Unfortunatelly the LG only supports checkerboard input for 720p and 1080p (though both @ 60Hz), while 3DTV Play can ouput checkerboard at all resolutions up to 4K.
I'm unsure if this option would be provided by a 3DTV Play license alone, which I don't own. I have actually the 3D vision pyramid connected to my PC (just used as "dongle" to get the 3D Vision/3DTV Play options). Of course I'm using the passive 3D glasses provided by LG.
[i]- Which 3D resolutions can be used with nVidia 3D Vision (pyramid connected, using LG passive glasses)?[/i]
With the ACER/LG EDID override you get line interleaved output for any resolution, which the LG is able to process at 720p, 1080p and 2160p (4K) resolutions. The first 2 actually need active processing by the LG TV (3D must be activated with line interleaved input selected), while at 4K the 3D "just works", because it exactly fits the polarisation filter layout of the passive LG display.
So, since there is no mandatory 3D frame packing for 4K @ 60Hz defined in the HDMI 2.0 spec, 4K line interleaved 3D is the best currently technical possible with the nVidia driver. This actually corresponds to 3840 x 1080 (2 * HD) resolution per eye, which looks insanely good at a 65" display with 1 m viewing distance!
[i]- Which 3D resolutions can be used with TriDef Ignition 3D driver?[/i]
TriDef offers also the side-by-side and top-bottom 3D formats (beside line interleaved), which the LG supports for all resolutions.
Also TriDef can scale up any game resolution to 4K before actually applying the interleaved format, allowing correct 3D alignment for any game resolution in (LG native) line interleaved 3D mode.
[i]- Has the PC to be connected to a specific HDMI port, has the port name to be changed to "PC" or "Gaming"?[/i]
All 2 HDMI ports apply to HDMI 2.0. The first 2 ports also can be switched to 4:4:2 and 4:4:4 chroma (by setting "HDMI ULTRA HD Deep Color" to On). So for best possible image quality with a modern GPU HDMI port 1 or 2 should be used. There is no need to set a specific name for the port, but the LG picture mode should be set to "game" to disable post processing and reduce input lag. This picture mode is actually a necessary requirement when using 4K interleaved 3D input, as the post processing would mess up the line allignment and the 3D effect.
[i]- How is the image quality with checkerboard input format (best mode for my previous plasma 3D HDTV)?[/i]
The checkerboard 3D input format is only supported by the LG at 720p and 1080p. It seems to be no good choice for a passive 3D TV. I compared the 3D picture quality for different 3D input formats at 1080p, and clearly top-bottom and reverse line interleaved looked at best, which is no surprise keeping in mind that the display uses a line based polarisation filter (reducing the vertical resolution per eye, but not the horizontal). Naurally all 3D input modes, that halve the horizontal resolution (side-by-side, row interleaved and checkerboard) would degenerate 3d picture quality more than 3D input modes that halve the vertical resolution (top-bottom or line interleaved).
[i]- What about 3D ghosting/cross-talk?[/i]
Overall I would say the LG has less ghosting than my previous Samsung plasma. There is actually a minimal ghosting effect. It It is not as good as with a DLP-TV or projector (that is actually ghosting free).
One thing I noticed is that 4K top-bottom initially caused less ghosting than line interleaved. After some investigation the reason seems to be clear:
When using top-bottom input mode, the TV has to be set to the correct 3D mode, so the TV actually "knows" it is running in 3D and can perform some necessary optimisations (e.g. adjust/switch off disturbing settings), while when using 4K line interleaved input the TV has no clue that it is showing a 3D picture. I had to adjust some LG settings to actually get the same quality/less ghosting than with top-bottom mode. The most essential are:
- Advanced Settings->Picture->Picture Mode = Game
- Advanced Settings->Picture->Advanced Control->Super Resolution = Off
- Advanced Settings->Picture->Picture Options->Noise Recuction = Off
[i]- 3D is all about immersion. What is the minimal possible 3D viewing distance?[/i]
I can confirm that at 1,2 m viewing distance the additional ghosting at the bottom and top screen edges caused by the parallax effect (caused by the distance between polarisation foil and LCD-display) is only minimal and absolutely acceptable.
[i]- I heard that LG TV sets produced in May 2015 have defective polarisation foil assignment. Is this true?[/i]
My TV is from May and while I have no comparison to other LG sets I can say mine is fine. The "left black/right white" test image shows a minimal missaligment in the upper left corner. I'm not sure if there exist any LG 4K TV where it is really perfectly aligned over the full display. I can say that in-game I do not notice this slight misalligment, actually the 4K 3D image quality is superb!
[i]- What about input lag?[/i]
I can't not really comment on input lag yet as this was not within focus of my recent investigations. But the LG TV set offers the special picture mode "game" for gaming, that removes all image post processing and should be used for games that require minimal input lag (e.g. FPS). I will update this topic once I have more infos.
[i]- Are there really any games playable in 4K-3D?[/i]
Ok, I have a single GTX 980 Ti and was surprised that all games I tried so far have sufficient frame rates (30 - 60fps) to be playable in 4k with none or minimal reduction of graphical quality settings. I used to play games in 3D-HD with strong AA and of course can now reduce it or switch it off completely. Some games I've tested:
- The Vanishing of Ethan Carter
- Mafia 2
. Tomb Raider
- Sleeping Dogs
- Life is Strange
- DOA Last Round
[i]- So is the update from active HD 3D to passive 4K 3D worth it?[/i]

I can currently not really comment on input lag (you see from my tested game titles that I'm not a hardcore FPS guy). DOA, which is a really fast 60 fps fighter game, seems to be ok at 4K 3D in LG game mode.
I will investigate further regarding input lag for different LG picture modes / 3D input modes / resolutions and report back later when I have something to share (editing my original post).

Note that when using 1080p resolution with 3DTV Play, the unnecessary NVIDIA constraint forcing the Desktop to operate at 24 fps introduces an additional 17 msec or so of control lag, not experienced with the EDID mod and Optimized for NVIDIA GeForce 3D mode. I suggest not using 3DTV Play until NVIDIA fixes this ancient product.
Also note that even projection 3D systems are limited by the performance (including optical extinction) of the polarized filters, screen, and viewing glasses. The only ghost free displays use separate displays (or retinal projection) for each eye, like Oculus Rift and Sony VR.
In other forums, I have seen members use tools like Rock Band 3 to measure TV input lag. For example, AuraWind in AVS forum measured the input lag (Gaming mode) for my UB9500 to be around 55 msec, not ideal but acceptable.

One of the easiest ways to test if lag is acceptable, is in a game that uses double jumps.
DarkSiders 1, is a good test if you have it. When double jumping, he sprouts wings. If you can easily do it repeatedly, you are good to go. If you consistently fail or stuggle to get the second jump off and sprout his wings, good luck playing any platformers.

Nobsi, thanks for your detailed review of passive LCD. But since you mentioned DLP projector, how do you think your 65" tv compares to it? I'm currently playing more or less same games as you - Life is Strange for example, and do it now on Benq DLP projector on 135" screen. But resolution of 720p is really really too low there. So I'm thinking is moving to 4k but much smaller screen with some ghosting makes sence or no?

For ghosting comparison, I suggest using something like TriDef's high-contrast test pattern (see [url]https://www.tridef.com/forum/viewtopic.php?f=16&t=1988[/url]) and NVIDIA's Control Panel 3D Test application (although, it does not appear to work with EDID mod and Windows 10).
I encourage anyone thinking about migration to passive 4K 3D display to go ahead and do it. My LG 4K has less ghosting than any of my prior 3D displays (plasma HDTVs, PC monitors, and active LED HDTVs). However, a GPU like GTX980 Ti is really required (see [url]https://forums.geforce.com/default/topic/818183/3d-vision/gtx-970-4k-3d-vision-gaming-success-with-lgub850v-passive-tv-/post/4693711/#4693711[/url] for more comparison).
I think my ultimate 3D 4K display may be Samsung's pending OLEDs, but ONLY if they support 2160p30 (beyond HDMI 2.0's formal 2160p24 spec, but within 2.0's bandwidth limits) AND NVIDIA finally fixes their ancient 3DTV Play to work with HDMI 2.0 and (asynchronous) 60 Hz Desktops (for higher resolution and more responsive gaming control). Active OLED ghosting will need be acceptable, as well.

I'm not sure if there exist any LG 4K TV where it is really perfectly aligned over the full display. I can say that in-game I do not notice this slight misalligment, actually the 4K 3D image quality is superb!
- What about input lag?
I can't not really comment on input lag yet as this was not within focus of my recent investigations. But the LG TV set offers the special picture mode "game" for gaming, that removes all image post processing and should be used for games that require minimal input lag (e.g. FPS). I will update this topic once I have more infos.
- Are there really any games playable in 4K-3D?
Ok, I have a single GTX 980 Ti and was surprised that all games I tried so far have sufficient frame rates (30 - 60fps) to be playable in 4k with none or minimal reduction of graphical quality settings. I used to play games in 3D-HD with strong AA and of course can now reduce it or switch it off completely. Some games I've tested:
- The Vanishing of Ethan Carter
- Mafia 2
. Tomb Raider
- Sleeping Dogs
- Life is Strange
- DOA Last Round
- So is the update from active HD 3D to passive 4K 3D worth it?
Are you kidding?

I can currently not really comment on input lag (you see from my tested game titles that I'm not a hardcore FPS guy). DOA, which is a really fast 60 fps fighter game, seems to be ok at 4K 3D in LG game mode.
I will investigate further regarding input lag for different LG picture modes / 3D input modes / resolutions and report back later when I have something to share (editing my original post).
Also note that even projection 3D systems are limited by the performance (including optical extinction) of the polarized filters, screen, and viewing glasses. The only ghost free displays use separate displays (or retinal projection) for each eye, like Oculus Rift and Sony VR.
In other forums, I have seen members use tools like Rock Band 3 to measure TV input lag. For example, AuraWind in AVS forum measured the input lag (Gaming mode) for my UB9500 to be around 55 msec, not ideal but acceptable.
DarkSiders 1, is a good test if you have it. When double jumping, he sprouts wings. If you can easily do it repeatedly, you are good to go. If you consistently fail or stuggle to get the second jump off and sprout his wings, good luck playing any platformers.
what exactly are the major differences between 55UG870V and 55UB950V?
Apart that is curved.
Thank again
I encourage anyone thinking about migration to passive 4K 3D display to go ahead and do it. My LG 4K has less ghosting than any of my prior 3D displays (plasma HDTVs, PC monitors, and active LED HDTVs). However, a GPU like GTX980 Ti is really required (see https://forums.geforce.com/default/topic/818183/3d-vision/gtx-970-4k-3d-vision-gaming-success-with-lgub850v-passive-tv-/post/4693711/#4693711 for more comparison).
I think my ultimate 3D 4K display may be Samsung's pending OLEDs, but ONLY if they support 2160p30 (beyond HDMI 2.0's formal 2160p24 spec, but within 2.0's bandwidth limits) AND NVIDIA finally fixes their ancient 3DTV Play to work with HDMI 2.0 and (asynchronous) 60 Hz Desktops (for higher resolution and more responsive gaming control). Active OLED ghosting will need be acceptable, as well.
