I had to return or sell both the 14” MBP and the M2 13” Air because of eye fatigue in using the screens. They have a harshness to them that makes it difficult to focus on over long periods of time. Some people have equated it to the feeling of looking into a flashlight, or a pinching feeling behind your eyeballs. It’s exhausting.
The issue is well-documented on this forum with some searching. It appears to have started with the m-based processors. No one is absolutely certain what it is - PWM, dithering, refresh rates, etc. Going back to my 2017 is instant relief, zero issues.
And yes, I have tried every fix offered under the sun for the problem, spent way too many hours researching solutions the first go-around. Ordering this new 15” was based in hope that they may have subtly addressed it, but it’s the same as the 13” was. I’m continuing to see if I can adjust to it.
Edit: if you don’t experience any fatigue with these screens, definitely don’t overthink it. It’s just one of those “yes, I have that” or “what the hell are you talking about?” situations
