hardcore eyestrain on TUF Gaming VG27AQML1A

[technicalitch]

i try to know what is happening to my eyes on TUF Gaming VG27AQML1A (27 inch 1440 ips 240hz) while using this monitor but i cant.
after i look on this i got extremely hardcore problems with eyes and brain
i was trying to find what causes that and i noticed i got huge pupil pain and eyes.
why im telling pupil? because pupil is focusing image like lens in camera.
problem must be with something in pixel structure or something because looking at this display is extremely bad. i had 2 ips before with also eyestrain but not hardcore like this monitor is.
i was doing some researches and trying to find cause and i went to this article:
scienceabc dot com/humans/why-does-looking-at-stripes-give-us-a-headache.html

why stripes makes us pain? why looking at lines are making us extreme pain and other things?
this is what i think can be problem in this monitor. watching moving objects is also very painful because of how pupil try to connect pixels to our brain see image

another thing:

what the hell are these rainbows when i put camera on my screen? for me its the cause of problem. anyone here can explain why it looks like that on camera and how its called in scientific way?

sorry for chaotic post but i got so much pain while i write it in eye. but i think my theory is close to figure out why so many people have this stoopit eyestrain. its about pupil, pixels structure imho not only pwm flickering etc etc etc

Have you tried clamping color gamut to sRGB? Either using OSD or using novideo_SRGB

i sent monitor back after 2 weeks. it was extreme pain to eyes. probably pixel structure caused my eyestrain
