  • 1$ fix for 90% eyestrain on ips panels

qb74 i dont know how to describe my cause. its more like neurological problems maybe? maybe astigmatism? but i was at doctor and had 0.5 astigmatism which is acceptable and a lot people have it without glassess. but when i look at screen not brightness is problem. brightness is only problem when i lower it and it flickers so i use flux at 100% brightness.

i have something in my eyes like my camera when looking at this screen here:
https://www.youtube.com/watch?v=lrmWU7i1B1I

in some positions camera see rainbow. i dont see rainbow but seeing image on monitor is pain for me
lines and pixels is biggest problem for me. when i look at monitor i see unregular lines, flashes, white circles. irregular shapes. and my eyes cant concentrate on screen longer because its very painful. seeing all these things is painful.

biggest problem i have is with monitor vg27AQML1A, its extreme pain even after 20 seconds looking at screen.
my eyes are watering, the next day my eyes are runny, sometimes i see blood in my veins in my eyes…

AOC Q24G2A/BK was better because smaller screen and higher ppi but i also had pain and feel that monitor is not natural vision for me.

"all of these IPS monitors are the same RGB layout."

maybe thats why i feel on all ips huge eye pain? i noticed on my old omen 25i i had huge problem with dlp rainbow effect that was on font and it cause my eyes hurt. but with this asus i have problem on whole screen. visible pixels make me pain.

    Seagull This is part of a story and does not explain device A causes strain on monitor A, but device B does not cause strain on monitor A. But for this particular might be appropriate conclusion.

    @technicalitch hi. Just a quick question. Is your problem with eye strain this: after a few minutes yours get heavy, dry and after a day or so of looking at the screen your eyes get totally red like they are inflamed? Just asking because this is my problem and I am a bit curious to try the paper ploy.

      brjdenis dont know how to describe it but its something like huge pupil pain when trying to look at screen to focus the image and on asus tuf monitor its also eye nerve irritation. the things you described happens when i try to look at screen even when i feel pain for longer time. usually after first pain i stop looking at monitor and i look anywhere else to my pupil change and then look back at monitor. its like refreshing pupil and my vision change. dont know really how to describe because my english sucks and its very unusual problems

      brjdenis i have same feeling when i see stripe lines like here:

      when i put it on monitor its ultra hard to see it, extreme pain, vision problems, multiplies of stripe lines etc etc

        and movement of images also causes me wanna vomit or something. no mprt mode is turned on or anything. with mprt i feel like im close to epilepsy attack

        Almost all modern LCD monitors are RGB subpixel layout, whether it is TN/VA/IPS, it's the same

        There are a few which are BGR, but this is not the case here.

        AOC Q24G2A/BK was better because smaller screen and higher ppi but i also had pain and feel that monitor is not natural vision for me.

        Ofc it is not "natural vision", it depends what you're doing with it. (gaming / reading web / scrolling viciously)
        To be able to get anywhere near "natural vision", you need a +1000Hz (properly compliant) and +200ppi display
        The next closest thing is 360hz panels such as the XL2566K, WOLED or >=240hz 1440p or >=360hz 1080p LCD (no Mini LED) laptop panels (and hope they aren't KSF phosphor, as this is completely untouched by reviewers)
        You could definitely have pixel inversion artifacts, as it's a potential panel defect but I think you just dislike the new backlight's employed and you dislike low refresh rate (really common issue people have)

        You are likely suffering from the wider color gamut of KSF phosphor (QDEF/Quantum Dot would probably be an issue for you too, as seen below)

        KSF (Nano IPS) - used in your Asus and potentially Omen too

        CCFL (old panels)

        typical WLED (like in the Q24G2A or XL2566K)

        but how to check how is my monitor polarised? any ideas?

        Just get a pair of polarised sunglasses and turn them around till they go black. Research into that.

          qb74 thanks for amazing answer, can you recommend me monitor 27 inches 1440p 165 hz+ that wont cause me huge eye pains?

            technicalitch hey you should look into irlens syndrome from what I'm reading of how your sensitive to lines/patterns and seeing flashes and circles.. their glasses can stop all of that for you. Especially the nausea and other symptoms from patterns/lines too. They can help you find the right colors to mix into lenses that calms the brain and stop that processing issue.

              jordan iread about this and this theory is imho too far because i never expected any problems before these ips monitors i bought 🙁

                technicalitch I mean I never had issues either till 2020 and they definitely help. Many people wear irlens due to that issue specifically, there's a whole irlens syndrome institute which they have brain scans of before and after wearing them with how they calm the brain. Just tossing it out there because I think it could help, it's no quackery I can assure you lol

                Edit: doesn't fix my screen issue but stops patterns making me feel off

                technicalitch
                This is extremely hard for me to do, as I've myself have had issues in finding a 1440p 240hz panel w/o one of these KSF/NanoIPS & QDEF backlight panels.

                UPDATE: here's a few other models I've compiled

                A few options to consider (all +200hz):

                1.) Omen X 27

                • has PWM backlight dimming (not sure at what % it starts but it's +1kHz according to rtings)

                2.) AOC AG273QZ

                • TN, only this review of it
                • Read the review in it's entirety, this panel as some flaws (0% brightness is 130nits, which can be very bright for some especially in dimly lit room, wider color gamut but no sharp peaks akin to other KSF ones)

                3.) Y27GQ-25

                • 240hz, uses same panel as above monitors - M270DTN02.7
                  (wider color gamut as with the AOC, potential eyestrain but idk for sure)
                  source

                4.) Odyssey G6 / old Odyssey G7 (1440p 27" 240hz VA curved)

                • it's QDEF / uses Quantum Dot / QLED, not KSF phosphor (potential issue regardless)
                • issue is scanlines which can be visibly seen, this is a common scaler defect common on these units)

                5.) Lenovo Y27gq-20 (27" 165hz)

                • Uses GSync module, not much else is known about it.

                Other than these 3, 99% of 1440p +200hz LCD monitors are with KSF backlight or QDEF backlight (or maybe there's other ones but they aren't reviewed / unknown to me at least, but I sincerely doubt it)

                6.) WOLED, divided into 2 categories:
                6.1) 1440p240hz ones (PG27AQDM, XG27AQDMG [glossy], LG 27GR95QE, XG272-2K-OLED, AG276QZD, 27QHD240, X27U)
                6.2) 4k240hz / 1080p480hz one (LG 32GS95UE, ViewSonic's XG323-4K-OLED2)

                • I cannot 100% vouch for this, due to it's issues. I've seen people have success with it over other options such as QD-OLED or NanoIPS however.
                • issues: subpixel structure, brightness dip / flicker (really shallow but it's there) @ every refresh cycle

                Perhaps venturing into 1440p 240hz laptop panels (16" or 18") is a better option? I have not researched into them but they seem promising.
                But, anything wide color gamut should be KSF phosphor or QDEF nowadays.

                Maybe you are someone who's only sensitive to KSF/NanoIPS and not QDEF panels, such as:

                There's also BOE panels, which are KSF phosphor but not NanoIPS (g24f, m32q, 28" 4k panels etc.) and older Sharp panels.
                You can also have monitor models share a panel but have a custom backlight.
                It's sadly trial & error...and a lot of review researching.

                Good XB273U GX review (shows SPD properly)

                Considering LG 32GS95U myself, as it supposedly is a true 10 bit panel, and only uses the white leds to render regular text pages, which would be something completely different from other things tested..See the right column on the image below.
