moonpie Is "Freesync premium" similar to VRR? I didnt find VRR but I found freesync premium which was turned off. Turned trace free to 0. Do you suggest to use "blue light filter"? Got one of those.

Any other suggestions on features/gimmicks to turn off?

    Is it possible to send a video here somehow btw? Took a slow-mo video of my screen. Looks like its flickering. Just wanted to confirm

    I dont have experience with VRR feature and comfort impact of it

    But I do have experience with high-frequency monitors, where decreasing refresh rate to 60/50hz lead to eye-strain

      moonpie Okay thanks. Btw I bought this monitor like 5 days ago. First 2 days the difference was crazy, felt so much better, headache so much better etc. Then after that started feeling worse again. It coincides with my computer starting to freeze randomly 4 or 5 times now which never happens usually. I'm hopeful something's up with the graphics or the computer that's causing the increase in symptoms again. Does that sound reasonable?

        moonpie ubuntu 22.04 won't disable the gpu.So it's not a good way for testing

          And thank you also aswell for your inputs @autobot

          How do you guys know if the monitor is dithering or not? Any video of what it looks like or how to spot it?

          moonpie even for testing

          even old win XP or win7 could be useful for testing, to check OS influence

          Get wide your mind, your not better than others

            moonpie I certainly wouldn't recommend it beyond testing, but given the influence of OS issues (compared to the past) I think offline testing with a set of "known known" to be a good start.

              ASUS ProArt PA278CGV Monitor

              The ASUS ProArt PA278CGV monitor, according to https://www.displayspecifications.com/en/model/53fc33b6, supports true 8-bit color, but uses FRC (temporal dithering) for 10-bit. You should ensure that the graphics card control panel is set to 8-bit to avoid engaging the FRC module.

              PowerColor Radeon RX 7800 XT 16GB Red Devil

              I'm sure the RX 7800 XT uses dithering when the AMD driver is loaded at any bit depth except the maximum value, which should be 12-bit, just like my former RX 6600. However, in Linux, starting from kernel v6.8-rc1, it should be 10-bit (?) according to this commit: https://github.com/torvalds/linux/commit/d5df648ec830cfd775bdacb3a3640c1e16de90f2. Try using ColorControl to disable dithering on the RX 7800 XT in Windows (https://github.com/Maassoft/ColorControl) and set the color depth to 8-bit in the graphics card control panel.

                  WhisperingWind The commit says "We use spatial dither by default for all output bpc (6/8/10)." Do you know in which context that statement was made? Because it almost sounds like by default the amdgpu driver uses spatial dithering (not temporal dithering) regardless of the GPU type.

                      WhisperingWind Ohh okay, very interesting. Because currently its on 10-bit. Will try to figure out how to change it to 8-bit.

                      Gyazo Link to the settings in advanced display. Sorry if links are not allowed. It says Bit depth 10-bit. So I guess that means I have dithering.

                          The FRC module of the monitor is enabled for displaying 10-bit color. You have temporal dithering.

                              WhisperingWind Okay thanks. Is it possible to change it? If so how? Found this Gyazo in AMD software. In case you dont wanna open the link. "10-bit pixel format disabled"
