  • huge pupil pain in all ips panels. did i found source of problem?

@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)

Or if you wanna stay on 1080p, XL2566K or XL2586X (this one uses QDEF backlight, different to anything you've tried)

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

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.

even my camera when looking at these monitors have this problem and i think same shit is happening with my eyes when looking at these displays. on the picture monitor is showing blank white image

is it flickering on video?

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?

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?

        brjdenis "a AOC" doesn't mean anything.
        The Q24G2A and your "AOC gaming monitor" could be 2 completely different panels.
        Panel + backlight is what makes a monitor, these are important in finding out the culprit.

          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.

                  Will make a full post on this later but agree with VA, I have recently found the first truly comfortable "external monitor" I've ever used, and it's an old 42" Sharp Aquos LC-42D64U TV from 2007 which has a VA panel.

                  (Rather ironic my most comfortable monitor is a TV considering my username lol…)

                  It even lets me fully disable auto contrast enhancement (like a "randomly changing backlight and black level depending on screen contents" kind of thing) in the display section of the factory service menu which had nearly 200 pages of options, lol, it was super comprehensive and the setting was hidden away somewhere near page 150 I think

                  I've been using it for 2 weeks now (connected to a Windows desktop with integrated graphics) and the image is so beautifully crisp, pure, comfortable

                  It also has a CCFL backlight, plus one of the best matte coatings I've seen on a display with no "foggy haze" or "rainbow" effects while still 100% eliminating glare. Subpixels look crystal clear up close despite the matte coating… I have no idea how they managed to achieve this LOL

                  Color gamut and contrast is also soooo much nicer compared to my usable portable devices which mostly have TNs

                  I will post once I can reproduce this with a similar VA TV with a more suitable size for a monitor e.g. 30" or 26"
