i think its related to this problem:

huge pupil pain in all ips panels. did i found source of problem?
- Edited
i also realised smaller resolution than native of display are causing less eye strain on some monitors. not sure why but i feel it much different
(@update: maybe because movement on screen was more smooth than in native resolution? thats my one theory)
+ rainbow effect on ips display causes some eye irritation i found
- Edited
another theory i have its about movement of image. when i look at ufo test my eyes act differently and looking at objects movement in ufo test makes me pain. maybe response time of monitor is too high or too slow and our eyes cannot adapt to it correctly? im not talking about hz now but some changes in hz to lower or higher made my vision different.
also changes of hz made my eye strain different and i can manipulate my eyes somehow but its not hz related imho.
sorry for spamming but i really try to find solution and maybe it will be help for someone in future
@edit:
maybe our vision looking at ips need more ghosting? because movement for example of hand in nature when you move and look at your hand your pupils concentrate on object and you see object clearly and everything out of your hand is blurred. when you look not at moving hand you see your hand ghosted. maybe these ips panels movement is too sharp and it causes problems? im not sure
but this is definitely problem related to movement too
look on forums i read a lot people hate motion blur in games and some people love it, maybe its also related to this problem somewhere.
actually i have 2 teories. some monitors give us this looking at stripe effect thats why our eyes hurts like here:
https://www.scienceabc.com/humans/why-does-looking-at-stripes-give-us-a-headache.html
second teory is with movement and speed of pixels. maybe if movement in ips panels will have more ghosting eyestrain will go down? not sure, i try to figure out
or maybe too high ppi causes our eyes react on movement with strain?
another thing about samsung s22b300 tn panel. it really made my eyes act different when looking at monitor but flickering was only annoying and rainbow effect. looks like this tn panel is more natural to eye
eye (pupil?) adaptation to screen is definitely problem because i noticed "training" eye made me less eyestrain problems but for short amount of time and my brain was so tired
and another theory it can be really maybe caused by astigmatism that eye cant adapt to screen correctly? but 0.5 astigmatism doctor says you need no glassesโฆ not sure this is all weird
conclusion atm is f*ck ips panels
can we slow pixels response time and make more ghosting to monitors actually somehow? if i do this maybe this will be solution for me and some of you guys to movement look more naturally
or the light is too hardcore for our eyes? idk this is my thoughts i have on this problem you can check it and analyse

dyac on - image sharper but movement is as you see. you have 3 reflections of image
dyac off - image is smooth
some counter strike players says they hate dyac on and prefer smooth move. thats why people with eyestrain prefer tn panels over ips? ips is in movement something like dyac and maybe that cause eyestrain? im right?
how to buy monitor that wont make us eyestrain?
open this:
https://www.testufo.com/framerates#count=3&background=stars&pps=2880&fullscreen=1
look at movement, and if movement cause us eyepain or your eye strains to see the image it means this monitor isnt for us because we will have eyepain
this is my conclusion for now
ok my thougts was good, its something with pixels and effect we have in eyes with stripe line etc
@technicalitch
I think you should not be hasty.
Pixel inversion isn't as common of a issue on IPS as you think.
In fact, it's more common on TN than it is on IPS.
It is interesting to me that you've tried different types of backlights (WLED, KSF phosphor/NanoIPS) and yet your issue persisted.
Have you tried looking into the polarization orientation using polarized sunglasses? Are there any displays other than the Samsung which are fine to you?
If you're adamant on TN, you got options such as the Omen X 27 (it has PWM as per https://www.rtings.com/monitor/reviews/hp/omen-x-27)
or the AG273QZ (no PWM)
https://tftcentral.co.uk/reviews/aoc_agon_ag273qz
Or if you wanna stay on 1080p, XL2566K or XL2586X (this one uses QDEF backlight, different to anything you've tried)
with this website:

all 3 monitors i mentioned in first post have problem
on hp i didnt noticed flickering, when i check with camera i see black lines but they are not moving
on aoc completely no flickering even when i change brightness
on asus extremely flickering and asus is worst for my eyes and i dont know why. looking at it is most hardcore shit i ever had
- Edited
tbh im not sure if my eyes will be ok with TN, i can test it and send it back if its wrong. i tested 3 ips panels so i should test TN and VA and OLED but its very problematic to buy monitor and send it back before 2 weeks period will end
when i look at ips i have something like rainbow effect with me eyes and it cause me most pain in pupil.

is it flickering on video?
https://youtu.be/zr_vcd2xV8Y
explanation:
when i dont move camera i see stripes on camera but they are not moving, they are only moving when i move camera up and down. its flickering or not?
can you tell me where did you read about different types of backlight because https://www.displayspecifications.com/ says all these 3 monitors are W-LED
- Edited
again huge eye pain on aoc. its definitely about pixel structure not anything else
it something like when i try to look at display and my eye is focusing to see image i feel instantly pain like someone hit my eye with laser or something especially on this asus shit

Are you sure you're not getting eye pain due to the low refresh rate of the AOC or due to light setup (perhaps flickering bulb or monitor being too bright in a not-well lit room)?
It uses a regular LED backlight.
165hz on the AOC is very blurry compared to something like the XL2566K @ 360hz.
Oh and btw, DyAc is a eyestrain issue for some (its strobing / emulating CRT's), don't bother with that.
It can get very sharp / clear without that "double imaging" (crosstalk), you just need to tune it.
When I purchased a new AOC gaming monitor a year or two ago, I felt exactly what @technicalitch is talking about. Don't know why, but out of all monitors I tried AOC was the worst.
@technicalitch you are running windows 10? Did you perhaps try windows 7 or some version of Ubuntu?
technicalitch Have you tried a projector? do you have the same strain as with monitors? do you have the same problem with VA tvs or IPS tvs?
Abeabe im not sure but i was using projector like 6 years ago and i had no problems as far as i remember. about va panel cant tell anything didnt tested it. what is ips tvs? its something different than regular ips?
update: i tried today to use asus tuf gaming monitor even with huge eye pain as much as i can stand but it completely destroyed me, i felt like i was close to death. total disaster to my brain, bod. all i know i will never adapt to this monitor no matter what, sadly.
