I have MacBook Pro 16 M2 Pro, with macOS Sonoma, and I noticed I have a pain in the eyes when I looking to the built in screen or external screen. its a pain which I can live with it. I tried to adapt to it for a week and I felt like I'm sick.
I suspect the problem is temporal dithering.
I tried the solution with dummy screen with BetterDisplay but it didn't worked. I tried to run the line which disable the dithering via terminal but didn't help. even I checked in safe mode if its occurs, and yes! how strange it sounds it occurs! I thought in safe mode the gpu should not work so the dithering will stop there.
the strange thing is, I have an external display in my house which support HDR so I tried to enable it, but nothing helped.
BUT, when I used BetterDisplay to make the full brightness over the 100%, at full after that, at 156% full brightness and the pain in the eyes disappears! what a strange situation!
so I tried the same in the build in screen of the MacBook, I put over 100% of full brightness, 160% full brightness and the same occurred! the pain in the eyes disappeared!
when I low the brightness even in one level, the pain in the eyes comes back…
so my question is, if the full brightness solve the issue, is it temporal dithering? I have another screen at my work, simple screen of Dell 24 Inch, and I don't have an HDR mode in that screen so I don't have a choice and need to suffer this pain in the eyes… also, as I know, a full brightness on the MacBook will drain the battery very fast, and I need the MacBook for long time sessions on battery mode without a charger and its hurt in its battery performance so its hard to work like that.
what is the problem if it isn't temporal dithering? there is a solution for this?
