New Graphics Card (RTX 3090) Gives Eyestrain

Thanks, do you re-do this each restart or only once ever?

This definitely helped!

Also interesting NvColorControl comes up on Malwarebytes with PUP.Optional.SearchProtect

screengazer Hi, how are you feeling now with your new monitor? I'm also having issues with RTX 3090 on 3 different monitors, but it seems to make it even worse if I change color output format from RGB Full to YCbCr422. So I guess GPU doesn't cause me problems (with RGB Full), but all of these monitors cause it for some other reason. However, it might also be that the GPU is causing the problems - just different color formats use different kind of dithering and thus the symtoms are different (eye strain only VS. eye strain + hard to focus). But... I'm not sure how to test whether it's the monitor or GPU.

Does anyone know why NvColorControl helps so much? This combined with IntelPWMControl (can't figure out which one is helping). Strange if it's the latter given I have Intel properly disabled, removed from Device Manager etc and there's no PWM (based off slow-mo mode on iPhone)

Quad43 Does it eliminate your symptoms completely? I'll also try this and would let you know.

MPaz I'd say makes 90% better. The best was using Ditherig 1.11 which I can never get running now

Quad43 Which windows version are you using?

Windows 10 latest

Think I made an error by doing the very latest Windows update, 1.12 won't work now either, only 1.14 and it doesn't help as much

How did you determine that it doesn't work anymore?

This is very peculiar. Only you have this problem. I wonder if it's a video driver version # issue.

Quad43 Does anyone know why NvColorControl helps so much?

I never ever got it to work ever... it always threw an Nvidia API error no matter the version of Win 10.

each restart…

But this is only one of the possible options

NvColorControl makes changes to the registry at:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\nvlddmkm\DisplayDatabase\xxxyyyzzz]

"DitherRegistryKey"=hex:db,01,00,00,10,00,00,00,02,00,01,04,f3,00,00,00

and is consistent with the testing of temporal dithering switching on NV Quadro

In the ideal case, such a modification of the registry should lead to a constant result.

But in practice ...

1. sometimes the launch of the NvColorControl leads to an explicit improvement immediately
2. sometimes the launch of the NVControl leads to an improvement only after the preliminary removal of the registry branch \nvlddmkm\DisplayDatabase
3. sometimes helps first turn on & then turn off dithering through the NvColorControl
4. sometimes after the reboot, everything is fine without launching a NvColorControl (only with changes in the registry)
5. sometimes nothing helps

A lot of variables in this problem, I can point out the following:

1. exactly depends on the model of the GPU (gf1030 in my case)

2. exactly depends on the driver version (older is better)

3. exactly depends on the operating system version (win 7)

4. Perhaps depends on the fact that the any color profile is turned on

5. Perhaps it depends on the monitoring programs like speedfan

6. Perhaps depends on any program that switches video mode

   
   

   sometimes-perhaps-sometimes-perhaps-sometimes-perhaps for the year and there is no stable result

   I'm tired

   my current configuration at work Radeon X1650 + MS driver 8.56.1.16 from OS + Win7 = 8 hours of good work

   my current configuration at home 750ti + 361.43 + NvColorControl + win7 = acceptable result, sometimes

AgentX20 I never ever got it to work ever... it always threw an Nvidia API error no matter the version of Win 10.

1. Model GPU?

2. Full version of the operating system?

3. Driver version?

glvn Thank you very much for posting this. There are many factors to consider!

@screengazer Did you fix your issues?
