Hello, I bought last week an Alienware Dell AW3423DWF monitor. It's my first OLED and curved monitor. I like the colors, however I get a dry/sandy eyes/slight burn feel when I am using it. I sit at 60-70 cm from it and I wear glasses with blue light reducing lens. On my former LG IPS I did not have this problem.
I read about monitors using PWM to keep the brightness level and I was wondering if this could be the case here.
I did the test with the phone camera's shutter speed at 1/8000 (I don't have lower).
In the first pic, it's my display at 100 brightness and 165 Hz. A lot of dark bars appear and they seem to flicker very quick, as it is the case in this video: https://imgur.com/a/nazSvqo. Is this the PWM flicker issue?
100 Hz is similar. I tried at 60 Hz (second picture in the top link). At 60 Hz, I can only see a single dark bar which does not seem to flicker like the ones from 165 Hz and it seems to slowly move across the display.
I also tried this PWM test from the website with the moving UFO: https://www.testufo.com/blurtrail#foreground=ffffff&background=000000&thickness=1&height=480&ppf=16&separation=1000
At 165 Hz and 100 Hz, I'm seeing what's supposed to be a single line that moves as three or four lines.
At 60 Hz, it looks like a single line, a bit more wide.
Also, I don't see any difference in those tests (normal pic with the shutter 1/8000 or the moving line) at lower brightness vs 100% brightness.
Based on what I presented, what can it be assumed? Does this sound like PWM flicker? Does it seem to be better/absent at 60 Hz? Are there any settings that I can use to mitigate some of these problems? (I read about setting the brightness to 100% and then reducing it using software).
P.S. In the third image, the one with the green circle and arrows, there's a strange wave pattern that appears. Is that relevant too?
