So much info here idk where to start. Have had extreme pain behind eyes for 10 years, light sensitivity, sensitive to screens etc.

Monitor: Asus proart pa278cgv(just bought, maybe a mistake, tell me if it sucks).

CPU: Intel Core i7 14700K.
Motherboard: MSI MAG Z790 Tomahawk WIFI
Graphics card: PowerColor Radeon RX 7800 XT 16GB Red Devil

Using windows 11, any settings I can try changing to see if it helps?

    Jl1994 Welcome home son (or daughter). As for solutions - its a complex matter encompassing tech issues such as various types of flicker, actual LED light, then it relates to actual usage patterns, and then finally actual inherited medical conditions you might have (astigmatism or whatever)

      Jl1994

      First step: use an os that is is good for the eyes, that doesnt use the gpu, just to test if your display feels good to your eyes. Test it for a day or more. Share your results here.

      The operating system is ubuntu 18.04. You can use it with a live usb, No need to install.

      Also, connect the monitor using display port. Its better this way.

          autobot Can I use my computer as normally without GPU? For example I play a lot of poker, is that possible still? Also I'm not really sure what you mean by "You can use it with a live usb" How does that work exactly

              Jl1994 Yes, the i7 14700K has an integrated GPU. It's obviously not as fast as a dedicated GPU but enough for light computer usage such as editing docs, surfing etc. It should also be possible to play Poker on a website.

              Live USB just means that you can install Ubuntu on a USB Stick and run it from there as well without installing it on your PC.

                moonpie Lower refresh to 60/70/75Hz (probably not needed)

                I do not recommend to reduce refresh rate due to some inversion artifacts visibility in gaming monitors.

                To mask such patterns, its very important to keep very high refresh rates

                    simplex Do you agree with the other suggestions? Disabling VRR and Trace free techcnology for example

                    Edit: Just did a quick search on VRR on the forum, seems like everyone agrees to turn it off. Didnt find much on trace free technology. Appreciate all the help guys.

                        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

                          Jl1994 Disabling VRR and Trace free techcnology for example

                          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?
