So both of my 1080p 360Hz IPS monitors (one Alienware AW2521H, one Asus PG259QN) give me eye strain. It usually starts as a burning sensation then minor headache between the eyes. They have a polarity where polarized glasses are immediately DARK when I put them on. The displays that don't give me eye strain are my LG C1 and laptop IPS, both of which are still CLEAR when I put the glasses on. I believe this means my eyes prefer vertical waves but I may be mistaken. I came to the realization I don't really need 360Hz, but I do like G-Sync. I still would want to go with two 24/25" monitors as with my current setup I get about a 40 viewing degree angle on the 25" monitor, and I want to move up in resolution but am aware 4K is basically impossible to get below 4K without sacrificing options. I really do not want to go 27", but anything from 1080 up to 4K, and at least 120Hz, is fine. 24" 1440p is probably what I will go with in the end. I do have high standards for color accuracy which is part of why I bought the 360Hz monitors as they were actually the most color and gamma accurate high-refresh / non-art panels available in 2021. But the main concern is getting a pair of monitors that won't cause eye strain. Anyone who had eye strain with the AW2521H or PG259QN and moved to a new monitor with good results? Is there a database for monitors that separates them based on polarity?

@"TrantaLocked"#p24636 Hi. Do you want to play games on the monitors or is it work stuff too? Why arent you using an LG C1 for your PC/console aswell? I think testing it for 1-2 days would be super valuable information, because if you get eyestrain on the C1 too, it may be another cause(lighting, GPU dithering, neck problems, brightness/contrast/saturation/sharpness settings). I say that because i wasted already thousands of € for things that didnt help my symptoms at all. ;) Are you sure your lighting isnt hammering into your eyes and causing the strain? For me some 1000hz light bulbs are 10 times worse than my 60hz PWM-driven flickery TV. I will get my LG 24GL600F today(i hope) and will share when i have it. Not wether it works with your glasses but it at least flickerfree(your 2 monitors are flickerfree too). There is one user who tested it and his strain was gone and he settled with it(dont think he is active anymore). I will share in a few days, when i was able to test it. And i dont know wether there is a database about monitors with polarity. Just saying, test wether rest of your setting is ok. Perhaps even use only one of the two monitors for a week each to see, wether one is just defective.

@"hayder1983"#p24637 I play games and use the internet mainly. I do use the LG C1 for my console but I use my computer when I want dual monitor and for mouse and keyboard for games I prefer that control setup. I do not get eye strain on my LG C1. My lighting as in room lighting? I usually keep it pitch black whether I'm on my phone, laptop, TV or computer. I have tried with just one or the other and it's the same effect and for both monitors. I am looking into VA panels. There was a big inrush of 165Hz VA panels over the last few years and I will be demoing a few of them. Color accuracy will probably be worse than what I have now but I'll be fine with a calibrated ICC profile. My previous monitor Samsung 2494SW was 6-bit+ FCR and didn't cause issues so I don't think I'm sensitive to dithering. But I do believe I'm sensitive to certain PWM implementations, not all but some of them, and I may also be sensitive to some of the newer types of LED backlighting used (yellow phosphor vs red+green phosphors?) but I'm not sure. For the 1080p 360Hz displays I own, I suspect the strain comes from the horizontal polarizer and/or other layers used besides the LCD panel itself like the matte surface or something. Because focusing on the panel itself is difficult for some reason, like even though there is no dithering or PWM, it doesn't look or feel "stable" to look at, but I'm not sure if that causes the eye strain or is a separate issue. It could be an overly stronge matte finish because my other matte panels I've owned in the past were never as aggressive as the AW2521H/PG259QN in matte grain. Looking at my laptop IPS (technically HADS IPS), phone OLED and TV OLED is just easier to focus. It's sort of like how e-ink displays are easier to read.

@"TrantaLocked"#p24655 Cant really suggest much, because you are searching for 1440p 24 inch and i only tested 1080p 24 inch. But perhaps try 2 TN Panel. A TN Panel might trigger less strain for your eyes. When you try a entry level TN-Panel you might get sth with a more conventional backlightning. I am testing the LG24GL600F right now, but it is too soon to say anything right now.

@"hayder1983"#p24671 I'm trying the SAMSUNG 24" Odyssey G32A 1080p 165Hz VA as we speak. It's vertically polarized (AW2521H 360Hz is horizontally polarized). I think my eyes like the Samsung. I will need to test for a bit to see but so far it does seem better. It also has lots of good options like gamma and response time, which can only be used when VRR is disabled unfortunately. The typical VA trail is long as always but color ghosting is reduced when the response is set to faster or fastest. It's capable in terms of color and can do about 96% sRGB according to the SpyderX calibrator, so with calibration it looks really great but it already looks very close to perfect out of the box. I can definitely say that I don't get that "looking inside an oven" feeling I that get from the AW2521H after looking at it for a while, but I think eye strain is still very slightly there. If my LG C1 is no eye strain, the G32A is like 2/10 eye strain, and the AW2521H is like 9/10 eye strain. The eye saver setting on the G32A definitely does slightly reduce eye strain funnily enough but it's bad for picture quality. MBR does make for a very clear image (though still with a long VA trail), but eye strain increases with it. Also, I really do wonder if matte grain strength has something to do with it though.

@"TrantaLocked"#p24695 My polarization and PWM recordings so far: \-Alienware AW2521H: Horizontal Polarization, NO PWM \-Asus PG259QN: Horizontal Polarization, NO PWM \-Samsung G32A 24": Vertical Polarization, NO PWM \-Acer Nitro KG241Y: Vertical Polarization, NO PWM \-ASUS VG247Q1A: Vertical Polarization, NO PWM \-Samsung 2494HM: 135° Polarization (diagonal NW/SE), YES PWM under 100% \-LG 24GL600F: 135° Polarization (diagonal NW/SE), NO PWM under 100% \-LG C1 55" : Vertical Polarization, NO PWM \-Galaxy s10e OLED: 135° Polarization (diagonal NW/SE), YES PWM under 100% \-BOE NV156FHM-NY1: Vertical Polarization, YES PWM under 100% \-BOE NV156FHM-N4B :Vertical Polarization, YES PWM under 100% UPDATE: I bought a circular polarizing lens and found that even with that lens, it still has a specific angle where it blocks light so I'm not sure what's going on. I thought for a circular polarizer, light output would be reduced evenly at all angles whereas linear polarizers block at a specific angle. I don't know enough about polarization to know for sure whether some of these panels are actually circularly polarized or linear, so I'm just going to include the darkness angle that I measured with my linear polarized glasses. The AW2521H and PG259QN also have a heavier matte finish than the other matte panels. There is one discovery I made which is many displays come with a slight green-leaning color temperature which may be easier on the eyes but I'm not sure of this yet. I recieved a version of my old Samsung TN to test, and I discovered it's notably more green in temperature than sRGB 6500k, and so was my BOE NV156FHM-N4B, and my Galaxy s10e. Also, color ghosting is worse on a 2022 Samsung G32A VA than the 2009 Samsung 2494 TN -_- Insane display tech has barely changed or improved for your baseline after more than ten years. I'm still not 100% sure what all of the contributing factors are here for eye strain, but I do believe that polarization is a contributing factor. I do think my eyes don't like horizontal polarization, but some eyes may prefer it. The [polarization study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4528539/#:%7E:text=Like%20many%20animals%2C%20humans%20are,carotenoids%20in%20the%20macula%20lutea) does show that circular is supposed to be the best however. A higher matte grain could also contribute to reduced focus on text. A screen taking up more % of your FOV also contributes. Brightness level also contributes and I believe high contrast scenarios can be bad at high brightness. And I really am going to pay attention to the slight green-color temperature that I've seen in so many displays but I do think color temperature does contribute.

@"TrantaLocked"#p24764 I am just testing the LG24GL600F(TN-Panel). It has a sharpness that doesnt break my eyes, it has no oversharpness and no blurriness. I think it is because of the coating being more matte than on the VA Panel i own. Sharpness settings rarely help with this kind of strain, I think needs to be right kind of sharpness out of the box, otherwise you cant fix the sharpness. Overdrive only got better because of high refreshrates. On 60hz my old TN-Panel had a near perfect overdrive with nearly no overshoot(i couldnt see overshoot), no smearing, no ghosting, no blur trail, no visible strobing, it was really nice to play shooters even on 60 fps. I even prefered it for watching movies, because i liked the motion handling so much. The new TN-Panel i am testing is like a newer version of my old Panel, not as perfect, feels a bit cheap, but with LED backlight. I actually dislike VA-Panels. I like TN-Panel motion handling and even the saturated colors are less straining for me. IPS panel colors are similar, but motion handling is still better on TN-Panels. Things that my strain you(considering your old monitor was an 2009 TN Panel): * Sharpness(Mostly affects reading) * Coating * VA-Panel overdrive * Contrast(most people ignore that, but i think most people in this forum have at least a slight issue with it) * New phosphors/LEDs making your panel overly red or green or yellow(not all new panels use the new phosphors) * Peak brightness(white wasnt as bright on my old Panel, tested it side by side) * Brightness * Color reproduction If you have the VA-Panel and your old TN-Panel side by side try testing turning saturation to 200% and look at a test picture of the most saturated colors. Both screen will be pushed to the limit of their color gamut. If you get more strain from the VA-Panel you might have some problem with vibrant colors. If there is no strain at all, you know, that it isnt a factor.

@"hayder1983"#p24766 I'm also going to try that LG TN. I tried both the Samsung G32A VA and the Acer KG241Y VA and at first it seemed the Acer was better for eye strain than the Samsung, but it quickly went south after a few minutes. The Samsung G32A is tolerable but still not as good as the three other displays I like, Samsung 2494HM TN, LG C1 55" OLED and BOE NV156FHM-NY1 IPS. I find it strange that certain PWM displays hurt and others don't, because both the BOE IPS and Samsung 2494 TN use PWM and they're fine. I'm praying I like the LG24GL600F. Otherwise I feel like all hope is gone. If anyone here who has owned the Samsung 2494HM, is there a way to not get the error message when overclocking the refresh rate? The same settings for 75Hz worked fine with no error message on my 2494SW which is just a non-HDMI version of the same display.

@"TrantaLocked"#p24786 I think with the LG 24GL600F my eyes are slowly going back to normal. It seems to be very conventional, because LG needed something good and cheap. Main reasons: * saturated colors(they look normal to me, they dont shoot your eyes out) * sharpness * it doesnt use the new red-ish phosphors(otherwise even blue somehow gets red-ish) * no high frequency flicker The monitor stand is horrible, the monitor always is tilting to the right(0,3°) but my desk is not tilting… But you can fix that, the panel is a very conventional TN Panel with 144hz, normal TN Panel colors, and my eyes have for some reason no pain when reading. The last one is perhaps the most important, because my work is 90% reading and writing. Only one thing is that i reduced the saturation of the 6 colors to 47/100(50 being factory setting) and reducing contrast to 45(70 being factory setting). I am using it at 10/100 brightness in the morning(nearly no lights on) and go up to 25/100 when the sun shines(no glare) or even higher with glare. I also tried the Dell S2421HGF, but it seems to use high frequency flicker, it gave super hard pain even after 2 minutes of use. Colors were super greyish and ugly, not sure what it does better than the LG. PWM was very different with non-LED screens, i could use my old Panel for 14 hours and i did use it for 14 hours per day. And i have used 3 dozen of monitors with LED backlight(work, friends) in the last decade and never had any strain, most strain i got is now with the new screens and only in the last 6months, not sure why. I also was at a museum, they had some very old Samsung and NEC monitors showing some movies, and it was super pleasant to look at them. One was even showing a color test picture, it was totally soothing to look at! I had no symptoms with any of them. I am sure most of them had LED backlights. If everything else fails, i will get some old LED backlight monitors. But at the moment i think i can handle the LG. EDIT: If you still get strain, try turning off overdrive. It does strain my eyes a bit when turned on.

@"hayder1983"#p24794 I'm trying the LG 24GL600F. I'm not 100% sure if I like it yet. It has a 135 degree polarization like my Samsung 2494 TN and Galaxy s10e OLED. I may be able to get used to it and tweak some settings but it isn't immediately easier to look at than the Samsung G32A 24" or Acer Nitro KG241Y. I will however say other than my hesitancy on eye strain amount, the LG 24GL600F is the best monitor of all the budget 1080p 24" monitors I've tried. It has the best feature-set user menu, a 3.5mm audio input, light and sleek design allowing it to sit further back on the VESA mount, and of course the best motion clarity. This LG 24GL600F is absolutely insane for the $120 sale it's on. Anyone can go into buying this monitor with little to no regrets. The main drawback is the way the matte layer is done, which is that it makes the top end of the panel look darker at lower viewing angles. It is going to be a tough decision between the LG 24GL600F and Samsung G32A 24". The Samsung G32A 24", like all VA monitors I have tried, has noticeable color ghosting even with the response setting turned on. But it isn't very tough to look at. The Acer KG241Y seems to have a weak color gamut and is missing the audio input, and overall it's surprisingly barebones despite being in the same price range as the others. I do think the decision will come down to eye strain amount. I would hate to not keep the LG because it has such a great feature set and visual clarity, but if it ends but being straining I'd be happy to keep the Samsung G32A VA. And I can tell the LG is probably a bit too straining, and comparing to my 2494HM I'm starting to suspect the LED baseline color temperature really does matter a lot, because the CCFLs in the 2494HM are tad on the warm/green side and the LEDs on the LG 24GL600F are a tad more blue. This matters because no amount of color correction, whether in monitor or in software, can change the color temperature of the *black level and near-black grays*. It will ALWAYS be the color of the LED+other layers. I do suspect this black color temperature needs to be not too blue and possibly not too red for it to not be straining, and that makes me wonder if the old CCFL TNs are so easy to look at *because they aren't so blue like LEDs.*

@"TrantaLocked"#p24921 I am happy that the LG benefits you. I have returned it, because for some reason i had eye pain when it displayed motion. It was hard pain with the overdrive on and mild pain with the overdrive off. I also had mild strain when using it to read. It was much better than the DELL S2421HGF but still not usable for me. But motion being painful to my eye was new, i never had that before. I will try some business monitors with good motion handling. I am happy with every allrounder that does less strain on my eyes and opens up the possibility of casual gaming. The DELL U2520D arrived yesterday, perhaps i am more lucky with business model screens. I also think reddish LEDs in the screen are more straining. But my old CCFL had backlight which was like 5500K by itself and it was great to look at. :(

Recommendations for new monitor

TrantaLocked

My previous monitors were 360Hz; those were the ones that caused an extreme burning sensation, but it wasn't because of 360Hz because I tested them at all refresh rates. My eyes are fine with any refresh rate. Having more space behind the monitor to look at farther away objects is what I did when I moved my desk out, because I believe having far away objects to focus on periodically can help. The eye strain I get from many monitors feels like normal muscle strain, like the muscles that control contraction which is considered the "typical" eye strain. Some specific monitors give me a BURNING sensation that is totally different than normal strain. But I think it's possible my eyes no longer like either the diagonal polarization and/or the PWM of the Samsung 2494HM even though I didn't really have problems with it before (or it's different from the SW version). I think a part of this is just my eyes got weaker over the years and are now less resilient to stress, and now I really have to be careful in which displays I choose. Some PWM implementations there's no problem, like my laptop monitor BOE NV156FHM-NY1.

I went back to testing the Acer KG241Y VA and like I remember, it creates the least amount of strain out of all the VA monitors, even less than the Samsung 2494HM. The LED temperature is SLIGHTLY blue in tint but it's not extreme like the LG UltraGear TN and a little less than the Samsung G32A. The Asus VG247Q1A has pretty much the EXACT same LED temperature as the Samsung 2494HM CCFL temperature, but I think the Asus is slightly straining similar to the Samsung G32A 24". The Acer has nearly zero strain over long sessions. The other issue with the Asus is it has the worst ghosting of the VA panels. The Samsung G32A has the clearest VA motion and the Acer more like in the middle but closer to the Samsung G32A in clearness, so not awful but visible.

The Acer KG241Y is definitely not the best monitor ever but I guess something about it just produces less eye strain for me so I'm pretty much deciding to keep it, but I will try the Asus VG247Q1A VA one more time before I fully decide. I promised myself I'd keep at least one of these VA displays I bought in order to not fully troll the store I bought them from. But I think it was important to do this because I learned a lot about monitors and what to look for. Definitely if I ever do another round it will be for IPS, OLEDs or microLEDs and not VAs or TNs, but its unfortunate that it requires testing so many monitors over long periods to figure out which ones do and don't produce strain.

TrantaLocked

Believe it or not, the position I put each monitor has an affect on the amount of eye strain. There's a slight bias, for whatever reason, that makes the monitor in the left/primary position give me more eye strain, and the one on the right less eye strain.

The only real differences I can imagine here are distance, angle and background colors. The monitor on the left is closer to a wall to the left, while the monitor on the right has open space up to the doorway. The right monitor also sits farther away from me and will be viewed at a slight angle while I am head-on to the left monitor.

I don't really know what to make of this. I've gone back and forth to 100% confirm there is a slight bias in eye strain just based on left or right position regardless of which monitor is used. I guess it's probably the distance to the monitor that is mainly causing it but I don't know. Maybe it is the fact that when looking at the right position monitor at an angle, I see a lot more of the room which has a lot of far distance objects, while looking at the left basically all I see is up close or within like 4 feet.

hayder1983

TrantaLocked some people reported that distance from monitor to the wall affects their eye strain, while distance eye to monitor stayed the same. Try moving your desk farther from the wall perhaps?!

TrantaLocked

hayder1983

That's what I had tried earlier but it didn't help much.

hayder1983

TrantaLocked perhaps looking diagonally breaks the contrast? Perhaps your eyes prefer VA? LG C2 is a VA Panel.

Perhaps there is sth, that causes you strain, like a window in the side of your eye. I get strain from very bright light sources in my peripheral vision.

Maxx

distance will not help. TV's 6m from my eyes irritate the same.

Only older pwm free lcd's work. None of the modern flicker free displays are irritation free

I may be figuring out what it actually is. There are two factors: my eye prescription and the amount of contrast directly around the outline of the display, and it's easy to be fooled that a small room light is enough. I can explain.

The first issue is I definitely notice more eye strain if I use my long range glasses vs short range. But strangely, no glasses is still better than my long range glasses, which makes it clear that OVER-CORRECTION IS WORSE FOR STRAIN THAN NO CORRECTION.

The second issue is lighting immediately around the display. With my laptop, the light from the screen reflects off the keyboard (and remember when I said my new laptop monitor is easier on the eyes? well it's probably because my new laptop is SILVER (brighter) and my last laptop was RED (darker), it increases outline brightness!). My TV is so large it produces enough light to thoroughly light everything around it. But my monitor is both free-floating, small, and not flush to the curtains, meaning it can't really produce enough light to light the surrounding outline.

I was actually going back and forth pointing my phone light at the point below my monitor. The eye strain lessens soon after I point the light so the area underneath the monitor is lit.

Now what's interesting is that area isn't really super dark when I have one of my smaller lamps on, but it's still too dark anyway. The only way to really get it "bright" is with the room light on, which is way too bright. So the only reasonable way to fix this is to buy a standalone light that goes behind the monitor or on the desk under the monitor. I would want something that can light the area all around the monitor like what I see with my TV.

I DO NOT think overall lighting in the room matters that much. It is moreso the sharp contrast from the outline of the monitor to the surrounding. You only need like 1-2 feet of the area around the monitor to be lit somewhat to create more of an equalization.

One of the problems for the monitor in relation to like a phone used in darkness, is that even though both are being in used in darkness, the monitor will be far worse if there's no edge lighting since it tends to fill more of your FOV. The only way to really change monitor FOV at least in my case is to get a deeper desk which after searching online, is prohibitively expensive if i want to be picky with dimensions. Nothing really cuts it.

So what I'm going to do is find the best way to get good lighting all around the monitor. Probably a light that goes behind and maybe one below so the bottom bezel is also lit somewhat. I have some paper taped to the bottom bezel while I look for lights. These are what I'm going to test first: 1, 2, 3. There are some other cool RGB lights that are just too expensive. I will also get a new pair of glasses even better for the exact distance I use my desktop monitor at.

And that's pretty much it. I believe when it comes to preventing my eye muscle strain, it is a combination of not overcorrecting with my prescription and making sure the area immediately around the monitor bezel is well lit. As I explained, these areas are better lit for both my TV and laptop in pure darkness due to the reasons I explained above. The desktop monitor is the worst case; large FOV, lamps have trouble lighting the surrounding area. PWM is also an issue but not all PWM is created equal, as I have no issue with the PWM frequency of my laptop panel. I have also tried to disable GPU enforced dithering with the program Calibration Tools but I have yet to confirm if this makes a difference.

When it comes to the burning sensation from my 360Hz monitors, again I still think it's either the blue LED temperature or the polarization, which for those panels was horizontal. I have a post in this thread with my polarization findings for all types of displays I've tested TrantaLocked . MOST monitors seem to have vertical polarization, with some rare exceptions having horizontal or diagonal polarization.

It is still weird because I never experienced issues with surrounding contrast causing eye strain. I don't know why it's suddenly an issue.

hayder1983

So i just sold my benq ew3270u. The guy testing it used brightness 100% and that gave me a hammering pain even though i sat 7meters away. At low brightness i had no pain, but moderate strain and nausea.

My phone can get really bright, never get pain or strain with it. Tested it shortly after his departure.

I am really really sure that pwm-free is nice, but some screens are still straining, because of the LEDs used. I need to test some older 2014 monitors to be sure, but i think the newest generation of w-led is causing pain to my eye.

EyeDiscomfortCertificate

hayder1983 Oh yeah, right now, while I am typing the message, my window (it is in the right peripheral zone) has exactly right brightness. Little darker or brighter - and it worsens the strain.

TrantaLocked

hayder1983 The C1 is an OLED. It's not to do with VA because my current primary is switched to the Acer VA with the Samsung 2494HM to the right, which is the direction that if I look it is less straining, which would be a combination of more distance and seeing more of the room in that direction. It does make me think it could be as simple as viewing angle, as my other screens usually make up less than 40 degrees but my primary monitor makes up about 40 and it could just be my eyes don't like it or something.

hayder1983

EyeDiscomfortCertificate too dark is straining too?

EyeDiscomfortCertificate

hayder1983 I mean, if I do not switch the lights on. Once it gets too dark I switch the lights on, and close the curtain, so the darkness does not distract me.

sss21344

TrantaLocked There are many Acer KG241 you mean Acer KG241 YAbmiix ?

Maybe I'll try this monitor, also the Samsung one.

hayder1983

Not sure. Perhaps the light is less 'in your eye' because of the viewing angle.

Basically it seemed like I get the least amount of eye strain out of the few VAs I tried with this one but what I'm discovering is that I still get eye strain with any monitor eventually, at least in the primary in front of me position. That didn't really used to be a thing before this year so I assume my eyes are less resilient now.

I did solve the burning sensation from my 360Hz panels that I think was either the LED temperature or the horizontal polarization, but now I am discovering another type of eye strain that seems to only really happen at my desk with computer monitors, but not with my TV, laptop or phone.

hayder1983

TrantaLocked Today is the first day i had no nausea at all, was able to work for 8 hours and i think i would be able to sit here another 2 hours. Still using the Syncmaster. Still using eye drops 4 times a day, no cortison. After taking the cortison nothing felt different, but the seven days i got out a lot. At least one hour of walking(just normal walking) and up to 4 hours a day. Even in my homeoffice i go for a walk now every day, so i can actually move a bit. This doesnt sound like much, but it actually helps my eyes. My eye pain is nearly gone. I hope this will not change, i will keep using the syncmaster and walking for 1+ hours a day.

hayder1983

Ok, this is weird. Using the follwing combinations results in:
Home PC + Syncmaster + HDMI + no driver = no nausea
work laptop + internal screen = no nausea
worklaptop+ Syncmaster + HDMI + no driver = nausea!!!

Seems like my nausea is somehow also related to driver issues?!

EDIT: I am not able to install drivers on my worklaptop. Every external screen is always with generic windows driver.

I can use an IPS monitor with an Innolux panel. Specifically the M280DCA-E3B found in the Samsung U28R550 is quite good. It is found in some other 28” 4K 60 Hz IPS monitors. What I would really like to try are Innolux 27” 1440p high refresh rate offerings, including the older K7B and especially the newer and faster K7E which supposedly improves on Innolux hardware-level low blue light tech already present on K7B.

All of these monitors use FRC so this is not a blanket recommendation.

The MSI Optix MAG274QRF-QD (AUO panel) gave me immediate and obvious pain.

EyeDiscomfortCertificate

degen I've heard many different opinions, but overall from what I heard is that AUO are actually easier on eyes. But digging deeper, I've come to conclusion that it is not only the panel itself, but backlight could be the culprit too (hovewer I own a BOE-panel based LG monitor, its backlight better than BENQ's one i also own, but I still cannot use it, for a different reason). Samsung often puts their own backlights into the panels they install in their monitors. OTOH, I've never heard anything bad about Innolux (esp IPS) panels aside from having difficult to remove red tint. The last Samsung VA monitor with AUO panel I've tried was good actually.

Elever

degen

Thanks @degen for the recommendation. I bought a 28" 4k 60hz Acer monitor, it's an Innolux panel like the rest, and I have not suffered from the same eye strain I was getting from 27" panels I tried earlier in the year.

Now, the monitor like apparently every single 28" 4k monitor on the market hilariously, does have some issues with horizontal pixel stretching as the ratio is not true 16:9 but I am not using it for any design or measurement accurate work so not a big deal for me.
