joelj Okay, I might return return the m1 then and get the m2. I use the iPad Pro 2021 11" no problem and iPhone 11 too, but I can't stand the screen of the MacBook Air m1. I lose focus fast and my eye hurts after using it for less than an hour. Did you try the MacBook Air m1 or just the Pro?
Has anyone tried the M2 MacBook Air?
Just the Pro and while it didn’t give as bad migraines as OLED screens, the words and picture didn’t seem ‘solid’ and stable like on my 2013 MBP. There Air they do, but I never tried the M1.
iPad Pro 2018, absolutely fine (but no PWM apparently)
joelj It's weird to me that while it's great that the system is working well for you, we have another thread here with slo-mo video of the same machine flashing away the screen. It's possible that other unit had a hardware failure.. are you able to take a look at your screen in slo-mo 240 fps mode with your phone and see if it's flashing away?
degen I use my iPad Pro 2021 11" with 0 issues, I don't feel any eye strains or something close to it. I use my windows laptop for work and connect it to two external monitors and I work hours behind these monitors with no issues too. When I received my MacBook Air m1 and connected it to the monitor, damn my eyes turn red in less than an hour and I can't focus on anything after that. I feel like it's the dithering that is causing the issue, I don't know if this issue persist on the M2 but Ill keep trying with my M1 and see if I get used to it. If the issue keeps happening with this M1 I will return it without thinking twice.
Moe3224 here you go, recorded on my iPhone 11 slow motion video, hope that's enough grey –

So what is the conlcusion now? M2 does not have Temporal dithering and now PWM. And some users who do have problems with many other devices with PWM, don't seem to have problems with M2?
If that is the case, I'll go buy one in an instant, though I'm strickly not a Mac user.

Maxx I see a few people on Reddit and Macrumors who say that MBA m2 was either not better or outright worse than MacBook Air M1. We really need more people to compare the two, although I do appreciate @eyestrainsolutions report that MBA M1 was better. @bkdo is also going to report when ready, who has experience with M1, no pressure 
)
I myself am trying to decide on a Mac machine, changed my mind to a laptop, to trial Ashai Linux (I am going to keep mentioning Ashai Linux everywhere any perhaps annoyingly because we could use some people to compare strain on that to macOS.)
degen I posted this in the other thread, I'll post it here as well -
I've been using the M2 Air for about a week now, it's definitely easier on the eyes in my experience. I still get a little dizzy after prolonged use, but it doesn't cause the gritty eyes, migraine, lingering pain above the eyes, etc. I'm actually planning on selling my M1 and just keeping the M2.
My setup is:
sRGB Color Profile
True Tone On
Auto-Brightness Off
Usually kept at 50% brightness
I'd definitely recommend trying this one out if the M1 gave you trouble

Macbook M1 has detectable PWM, Macbook M2 has undetectable PWM, Lenovo ideapad slim 9i don't have PWM, but these laptops all causing eye strain and headache. These laptops also cause you can't sleep at night if you use them before sleep.
It is the IPS screen problem, IPS screen will causing eye strain just because the light it emit is too strong. Because the angle they emitting light, and the area of one pixel is comparatively bigger. IPS screen light didn't be filtered well. Buy a screen filter won't help, it will help a little bit like fifty percent, but won't really solve the problem, I bought a privacy filter which said decrease 96% ultra violet and blue light. It doesn't help much.
445641544 I used to think that all IPS are tough on vision, but this is not true. I own HP Elitebook G4 it is the best screen I ever used (together with a very old TN). Very easy on eyes, great colors and contrast. It is an IPS.
I've never had noticeable issues with eye strain in the past. Been using an iphone 12 with OLED for 2 years without issue, and had an M1 MBA as well and was fine.
I recently picked up a 2021 Macbook Pro 14" with the XDR micro-LED display and after a week of torture determined that it is the display on the computer making me physically ill. Motion sickness, mild headache and general "off" feeling. I've never experienced anything like this from a screen before so didn't consider myself "sensitive".
After doing some research I decided to try the 2022 M2 Macbook Air based on good reviews, lack of measurable PWM, etc.
I'm pleased to report that I have no issues with the M2 Air screen, probably even more comfortable than my M1 Air one.
As a test, I went back to the MBP 14" again this morning after initially using the Air, and within 5 minutes I had that now-familiar pressure point on my frontal-lobe, and the beginnings of motion sickness setting in. That screen is a literal weapon, I really cannot believe how immediate and strong the impact is.
Anyway, FWIW, I find the 13.6" M2 Air perfectly fine, and the 14" MBP literally and almost instantly debilitating.

Independent of the PWM or dithering or whatever else seems to cause these issues, the promotion displays can cause motion sickness when they ramp the frame rate up and down. I noticed this with the MBP 14 and 16 as well as the iPhone 13 Pro. You can sort of disable it in accessibility settings. Although the wording makes it seem like it still reduces the frame rate in some circumstances.
Its a bit weird because I can use the 2018 iPad Pro fine, even with the variable refresh rate enabled. I haven't tried the newer ones. The Macbook Pros and Pro iPhones that use pro-motion bother me.

When you use an srgb profile on the m2 air, do you essential turn off the FRC because you’re not needing the wider colors of the p3 spectrum so there’s nothing that needs faking?
I've measured a Macbook M2 16 Pro and it has PWN that can't be turned off in any of the profiles.

I have been using a mabook air M2 15" 16GB for two months now and like any other macbook I have tried in the past it causes me: migraine, dizziness and sweaty hands/hot sensation.
I have tried disabling dithering via command string but I haven't noticed any improvement.
Using betterdisplay removes the hand sweat but the migraine and dizziness remains. I take 5mg of fluxarten and whit this drug I can complete the work day.
When I work from home, I connect the MBA via USBC --> DP to the LG 27GR95QE monitor (OLED 2K 240hz). With this setup I can work all day without betterdisplay and without fluxarten. I have a slight headache but totally acceptable.
MACOS 13.5
Edit: with the LG OLED monitor i am not able to use my gaming PC (W11 21H2 with nvidia 4070). So, as always, is a software problem.
