    This monitor is very cheap.

    The version of Mesa that version of the distro uses is 22.2.1 with kernel 5.19. Mesa is where they put the gpu drivers these days. So that card probably will have similar results with other distros using Mesa 22.2.1 and up. I know a lot of updates went into 23.0 for AMD, so it will be interesting to see how it goes.

Eyestrain:     No eyestrain feel confirmed, i can read for a whole day.

    I changed my graphics card from AMD to intel, because I doubt the eyestrain feel is also concerned with graphics card.

    It turns out AMD card produces eyestrain. Please use Intel card and avoid AMD in Linux operating system.

    I also tried ubuntu 23.04, no eyestrain feel.

      Like the RX550, this AMD RX6400 hurt eyes. For linux, there is an alternative choice - the intel Arc series card.

      I used Archlinux for a very long time, now I turn to Ubuntu, the result is making me happy, the white on the screen is so soft and I didn't feel eyestrain any more. Great.

      Wow so arc is really safe like I thought! Can you test the arc with win10 or win11?

        I see you're using Linux, which is interesting. The hardware - driver issue amdgpu vs mesa (open source drivers that include intel integrated and dedicated gpus) seem to be the problem with your eyestrain. We should not discredit AMD cards right away, though. Have you tried other OS using AMD GPUs?
        My personal experience as a Linux user on a Samsung SJ55W 34'' super ultrawide VA-panel monitor is similar, though… I recently switched to an Intel ARC A770 card and the eyestrain symptoms were not as pronounced. The monitor is still giving my eyes lots of trouble, especially glare (needs to be in a dark room with bias light). Still learning about what might cause the issue, maybe the width of the screen messes my eyes too and I need to sit much farther away than with my default dell 23'' p2314h ips (about 8 years old) which doesn't give me eyestrain …
        I always need to set the brightness to the lowest, my eyes can't stand higher levels at all… I haven't tried any of the newer technologies and to say I'm a bit scared to try and buy it after using samsung which probably messed up my eyes significantly…

          zimci Do you wear glasses? Have you tried to change a pair of glasses? I won't buy samsung products, because my previous macbook pro (samsung display) gives me very bad eyestrain feeling.

Eyestrain:     Eye strain exist.

              Dont use AMD card, eye strain still exists.

              I just built a PC as I'm experimenting with moving away from Apple and their flickering displays and wow AMD cards are awdul. I have now tried both the built-in UHD 730 and then a RX 5500 XT and the AMD card gave me almost instantaneous sore, dry eyes, a headache, nausea and neck pain within minutes as I tried to change settings and to turn off dithering by outputting native 8bit and limiting colour. This is on a PWM-free display with Windows 11. The Intel iGPU is currently tolerable but I'm still testing.

                languidicity Try Windows 10 versions 21H2, 21H1, 20H2, 2004, and 1809.1098 and see if any of those versions remove the strain with the 5500 XT. Its also worth trying Linux with that 5500 XT.
