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 🙁

            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?

              Sunspark It won't load - it gives me an error when trying to open it. Only 1.14 successfully runs 🙁

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

                I get "Failed to load a DLL" or "Failed to configure the registers"

                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.

                    Quad43 Thanks, do you re-do this each restart or only once ever?

                    This definitely helped!

                    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


                        Quad43 You can fully describe your configuration?

                        1. Model GPU(gf3090?)

                        2. Full version of the operating system

                        3. Driver version

                        4. Monitor connection type DP, HDMI..

                        5. Color format RGB, YCbCr..

                        6. Brightness range: full or limited

                        p.s. I also used Ditherig 1.11 with HD630, but X1650 is better for me(with MS driver)

                        p.p.s Sorry for my terrible English

                          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!

                              Seagull I do not see the circled options.

                              Did Nvidia remove this after a few years?

                              However, in the resolution settings I did find this which I changed to 10bit full color now:

                              I've gone through three different monitors now (IPS, TN and VA) and two different presciption glasses and still have eye strain… which now that I think about it might have started a while after I got a 3090…

                                  eobet

                                  Sorry I can't say if its changed - I've only used intel integrated graphics for the last few years. Its seems like you've plenty of options to try though.
