can DSR be used with 3D vision to break past 720p 3Dtv??

[narhicfd]

Can nvidia DSR be used to play games in a higher resolution then the 720p restriction placed by 3Dtv play?? I know how to enable DSR but trying to set resolution higher then 720p when in 3D mode doesn't work.

Must depend on how the signal is being interpreted by the monitor. With my 3D TV enabled device 3D will only come on with 1280/720 at 60hz. But you can also use DSR to set it at 2560/1440 and the monitor detects it as 720p. I'm sure it won't work unless it is a correct multiple though. Try 2560/1440 or an exact multiple of whatever the 720p on yours (I assume 1280/720)

I need the solution for this too. Couldn't find any solid information on this at nvidia forums. Just remember you had to add a custom resolution with CRU so that it doesn't conflict with the 3Ddrivers. But couldn't find any steps around this.

Thanks. I guess this is not possible on a benq1070 then. Tried it with factory edit and Sony-KDL55HX729-EDID. It doesn't want to activate frame packing. Seems like 720p/800p projectors are in luck here. Also not 100% sure how things are on W10 and latest drivers. Its been a while since I've really been using 3d vision this way.

Try manual down sampling on some displays.

3DTV Play + 4x DSR definitely works. I tested in the past (4 years ago) when I had two 3DTV Play projectors for a few days.

The general issue with DSR and 3DTV Play is that DSR always wants to downsample to 1080p because this is the native resolution of most devices. The simplest solution to make it downsample to 720p instead is to delete all resolution above 1280x720@60hz. Worked for me.

The other thing which worked is 3DNovices method to manually downsample via custom resolution in Nvidia Control Panel although I downsampled from WQHD via DSR to 1080p first and then let the custom resolution scale it further down to 720p. Either way it worked on both a BenQ and Acer projector to the time - however rainbow artefacts + low resolution made me send those projectors back. 720p gaming even with DSR is just crap like hell.

@Lizzard: I don't see any reason why it shouldn't work on a BenQ W1070. For me it worked on Acer H6517ABD and Optoma HD27. The Sony-KDL55HX729-EDID won't help as it also has 1080p resolution in the EDID. Use your original EDID and delete all resolutions beyond 1280x720@60hz via CRU. Also delete 1280x720@120hz if available.

After you deleted this do you remember if 1280x720@60hz was the only resolution in the nVidia control panel? Because I tried many things and all the resolutions still appears in the control panel after restarting the driver and the computer. Seems like the only time this PJ goes into 3d mode is when it detects 720p@60hz and 1080p@24hz. No other user friendly combination seems to make it work. Have no clue where the problem lies. 3dTvPlay and DSR are terrible friends. Or the PJ only understands these two resolutions. Which is why i tried the SONY edid too.

Thanks for the tips guys. This is not a train wreck. But would be cool to have some alternatives. Would like to record some 3dVision games that doesnt work in HelixVision or Tridef and are watchable in VR. Primarily to keep some memories rather than a retro gaming pc when similar titles becomes obsolete in the future. Cant really enjoy it while playing on a 27" monitor with little depth. Just tested Remember Me 720p recordings on the projector. While playing the quality is really good. But the recorded quality is terrible. Since the performance for this game is bad in HV I dont want to make a recording that doesnt do it justice. DSR works very well with Tridef performance wise here. But almost all the reflections are broken so it doesnt do it justice either. This is my main concern for getting this to work. For my end goal there is still one option. 3dVision still has the most leverage here.

Indeed. My experience is that 1080p SbS or TaB are better output modes to target.

There is slightly more pixels in 1080p SbS/TaB than 720p. More importantly 720p on a 1080p display needs a messy non integer scaling on both axis, SbS or TaB only need a clean 2x scale and only on one axis.

Lastly, using DSR to increase render resolution super sampling just seems more compatible with a 1080p SbS or TaB output than it does with a 720p output.

Right - I roughly remember this issue. Even for my old 720p projector I had a 1080p resolution which prevent DSR from working. For the 720p projector I definitely remember that deleting the HDMI Extension block wiped all 1080p resolutions but this also wipes 3DTV Play. Hmm now I'm really unsure how I solved the issue for 3DTV Play. Only thing I know for sure (concerning 3DTV Play) that DSR downsampling to a custom 1080p resolution which internally was a 720p resolution worked. However I had to set desktop resolution to 720p first before starting a game. For not losing the real 1080p resolution I created a custom 1920x1081 resolution (1 pixel more) which I chose ingame for 2D gaming. Otherwise selection 1920x1080 you will strand up in 720p.

So you have two options:

A) Create a custom 1080p resolution via Nvidia Control Panel which is actually a 1280x720@60hz resolution
B) Delete the HDMI extension block and all 1080p resolutions and change Product ID to match a 3D Vision monitor (e.g. AUS27B1). Make sure the 3D Vision emitter is plugged in, projector set to frame sequential 3D input and use your 3D Vision glasses.

Maybe there was an option C) - at least I thought that somehow you can wipe 1080p without losing 3DTV Play.

Do Not Forget
shell shockers
When using Nvidia's DSR, a 13 step Gaussian filter is used and can be adjusted to varying strengths to dial in the effect. subway surfers

https://www.nvidia.com/en-us/geforce/te ... echnology/

But before even going this route, try things like texture mods, if available.
Make sure the game is rendering in your Native resolution and not up-sampling.
Check to see if a better Anti Aliasing option will improve the image, some options, really degrade the sharpness and make everything look soft.
Also, if it's an issue in every game, try a new display cable or repeater, if you are using a long cable.

DSR's Gaussian filter strength can be adjusted to achieve the desired effect. Users can experiment with different settings to find the right balance between sharpness and visual enhancements.

Hello,
I can no longer get the DSR to work in 3Dvision on my Optoma UHD42. When I use it I can only see a quarter of the image.
It works normally if I don't activate 3D (and also in TAB). Is anyone still using the DSR with 3D Vision?

[EpsilonLyrae]

The major limiting factor is always going to be the 3d vision driver in this case. You can use DSR or a technology by any other name to internally render the game at a high resolution, but the final frame buffer is always going to be limited by the 3d vision resolution you're working with.

So let's run through a hypothetical real quick

Internal render with dsr: 4k
3d vision resolution defined by the driver: 720p
Actual panel resolution: 1080p

The final output to the monitor is still going to be 720p, and whether the driver or your monitor does that scaling will be defined by the driver.

Will a 4k render downsampled to 720p look cleaner than 720p native? Marginally so, yes, especially along edges and narrow details like hair and fences

Will this make an appreciable difference when it ultimately gets bilinear scaled to fit your 1080p monitor? Not really. It's still a 720p image scaled to 1080p, no matter how good your anti aliasing is or how high your super sampling goes, that never changes and in 99.999% of cases will not be worth the extra rendering power required.

[ZeGURU69]

I'm in 1080p and not 720p (but it's true that the topic mentions 720p)

I used it on Callisto Protocol in TAB mode on geo11 and I can tell you that the difference was really quite significant. I don't think I would have played the game without DSR because the aliasing was so bad, whereas with DSR 4x it was fine.

So I'd like to be able to use it in 3Dvision, but as soon as the 3Dvision driver kicks in, Windows can't resize the 4k image to 1080p. It works fine in 2D and TAB/SBS. Is anyone still using this technology with 3dvision or am I alone?

[ZeGURU69]

I tested with a 2080 ti at work: with the latest drivers, I only have a quarter of the screen appearing but with the 452.06 I have the whole image. As a result, the DSR would not work with drivers after 452.06 in 3DVision

[3DNovice]

[ZeGURU69]

I assume that when you played using over/under, you used the HDMI 1.4 input port.
Then for Frame Sequential, you switched to the HDMI 2.0 input port and are using "Generic CRT".

You might use Custom Resolution Utility by ToastyX (CRU) to remove all resolutions, other than 1080P.
Also make sure that the game is rendering at 1080P and not doing it's own up-scaling shenanigans

But, yah, DSR is more or less, just another form of anti-aliasing, there could very well be other options with better performance

BTW, why not try DLDSR
https://www.rockpapershotgun.com/nvidia ... e-than-dsr

In fact, I did a 2nd test on a non-3D screen in 3D Vision Discover. With the 452.06 drivers it was ok and with the latest drivers I only had a quarter of the screen. I also tested the first drivers for the 4090 and I also only had a quarter of the screen. I really think there's something broken in the drivers when using DSR and 3Dvision.

The DLDSR is exactly the same result.
