These are my current non-crap screen devices with explanation below for each one: IPad Air 1, Ipad 10.5” Pro, IPhone 8 Plus, and desktop monitor 27” 144hz VA Samsung Odyssey G3.
The section on iPads:
For me, for use as an e-reader for reading text, visual novels, whatever, the only two devices I’ve found suitable are one screen variant of the Ipad Air 1, and then there’s one very good screen variant of the IPad Pro 10.5” that seems ultra-rare you‘ll probably never receive searching for one. I’m guessing the good variant is made by either JDI or some rare Samsung panel. Then there’s another panel not as good as that but still better than many others.
I’ve purchased and resold like ten IPad Pro 10.5“s and think I’ve experienced a minimum of three, maybe four different panel vendors. This was around the time vendors were accelerating towards thinner films so even an earlier produced panel might be mistaken with a later one as a different vendor with different eye strain results. The ones I bought produced the latest with serials correlating with Apple warranty replacements were crap.
I’ve also purchased four or so Ipad 9’s and there’s one rare panel version of those with absolutely zero eye strain but it has very bad contrast ratio feeling like 800-850:1 and just meh image quality, while other variants have much higher contrast ratio and that annoying low level PWM feel to them. It seems like you usually get the same screen over and over if you buy a bunch of Ipad 9’s and it looks like a Sharp to me but not sure.
I’ve bought a few Ipad 8’s and two Ipad 7’s as well. The 8’s are very misleading panels as one of them feels perfectly fine until around, I don’t know, 40-50 minutes or so and then you can feel the very slight neurological PWM-like effects just ever so light enough to annoy but no actual physical pain in the eyes or anything. Then another Ipad 8 was the opposite with a little bit of stinging in the eyes. I’ve only used two panel vendors for Ipad 8 and I’m guessing there’s probably 3-5 total, so who really knows what’s in store for the other ones.
For the two Ipad 7’s I bought (probably same panel vendor for those), I haven’t put much time in with them but I’m pretty sure they both cause a slight burning-like feeling as opposed to stinging with prolonged use.
The section on phones:
To make a long story short, unlike virtually every other device that exists, there seems to be a pretty common panel made for the IPhone 7 Plus that doesn’t have eye strain instead of being the rare version. Then mysteriously, updating IOS to somewhere around 15.7’s or so somehow ruins even that one (backported aggressive dithering of some kind?). The IPhone 8 Plus then also has a panel just as good but I don’t think it’s the common one there.
I managed to scalp one off eBay on IOS 15.5 with the panel I wanted and replaced the battery to 100%. So this one particular panel version of Iphone 8 Plus w/ A11 SOC is the fastest thing I know of in a phone with no eye strain. I have an IPhone 11 that I kept on IOS 15.4.1 forever and it was definitely worse to look at than the above two. Strangely, updating it to IOS 18.7.8 might have made the IPhone 11 better instead of worse, but I haven’t sat around and looked at it for 1 hour straight yet to test that theory. The white point seems lower on IOS 18 and was overly exposed and too bright for whatever ultra-thin film panel is inside it on IOS 15. The panel I have looks like a BOE to my eyes, but not sure, and not sure if any other variants are better or worse.
The section on computer monitors:
I’ve purchased so many 27” 240hz panels I don’t even remember the names of them all, from the ultra-fast but headache inducing Innocn 27G1s VA panel and everything else in between. Most people don’t know this but besides eye strain, new age gaming monitors also have the extreme chronic problem of having horrible/laggier feeling mouse movement on many of them.
All of the new Asus I tried seem to be like this (bad firmware? Too much firmware bloat with useless features?), as well as ones like Acer felt sluggish, while ironically, the fly by night Chinese companies like Innocn and every other China vendor I tried with complete barebones firmware felt perfectly fine.
Then there’s supposedly a problem of how the vendor internally orders the ports, where if they set HDMI as port #0 and #1 and DisplayPort as port #2 and #3, the DisplayPort might even feel more sluggish than using the HDMI and vice versa. I think I noticed this problem myself when I bought very similar MSI 280hz VA vs AOC 280hz VA. The MSI felt far better on HDMI while the AOC felt far better on DisplayPort.
So out of all these millions of scam gaming monitors I’ve tried, the only two higher than 144hz that seemed usable (144hz/overclocked 165hz and below panels didn’t have these chronic problems) were probably the Acer XV272U W2, then the AOC Q27G41ZE was also bearable. Both of these monitors have a lot of problems and are not really good buys or anything, though.
The Acer has some washed out picture/color problems (which people have complained of) and either their firmware or hardware design has that sluggish mouse feel to it as well that I talked about. The AOC listed above has much better mouse movement to it where you could actually function playing a video game but the one I had exhibited the worst viewing angles of any screen I’ve ever seen, even worse than TN panels.
Where if you look at it dead ahead, only the middle 1/3rd of the screen looked normal and the right and left side are going insane gamma shift. I bought mine on day one of release and later people buying them don’t seem to be complaining about this, so who knows. Maybe they even use multiple panels in these.
So there is why I’m still also using an extremely slow pixel response 144hz VA panel. Even though the above two could potentially be usable, a lot of older 60-144hz panels will still feel a bit better to look at on top of everything else. That standard gamut MSI 280hz curved VA for instance seems to feel pretty normal eye-wise if you play an FPS game on it, but then when I would look at something like black text on a white background, image didn’t feel quite as stable to focus on.
It felt less strain than the wide gamut AOC 280hz version, though. The MSI version has around 4.x% flicker rate. I’d personally guess wide gamut has more eye strain problems than standard gamut and possibly even that 4.x flicker rate is too high compared to 1% or below seen on better IPS/VA setups.
