Disable P3 color gamut to reduce eye strain
TL;DR: Go to Displays -> Color, and pick some other color profile. Hopefully this post helps someone.
As some of you, I've been struggling with eye strain with the new MacBook Pros.
I got the 16" Pro about a month ago, but had to return it due to not being able to focus on text, and my eyes being fatigued after only a few minutes of use. Just now I received the 2020 13" MacBook pro, and had the same problem.
I have plenty of monitors and laptops, including a 2015 MacBook Pro, so the typical "your eyes are holding it wrong, Macs can't have issues" response Apple users jump to seemed absurd. I've also never been particularly bothered by PWM.
Long story short, after playing with settings and trying to compare this laptop to my 2015 Pro, I changed the display color profile to something else and... BAM! All eye strain immediately went away. I turned the P3 profile back on, and the problem returned. It's the weirdest sensation. I found the sRGB IEC61966-2.1 profile looks the best, but will need to do some more comparisons to see what looks closest to the default profile on the 2015 Pro.
My one regret now is that I didn't find this when I still had the 16" Pro, but maybe I'll be able to catch it on sale within the return window of this 13".
As to why this made a difference - my crackpot theory is that the ****** LG panels that Apple uses need to use dithering to approximate the P3 gamut, and changing to sRGB disables said dithering. Again, I'm not an expert on the topic, so this theory could hold no water.
