Disable dithering on M1/M2 devices
- Edited
mirza I sit about 10 minutes after entering this command. Currently, I don't have this laptop on the hand and I can check only on Monday. As my laptop has PWM, I can still have side effect of PWM. It would be nice if one who have MacBook Air 2022 check this command as according to reports it is PWM free.
It's probably placebo, but I have a feeling it's better. We'll see.
Once again, maybe it's placebo, but I have feeling things did improve somewhat after this command in terminal. Would be nice if some other folks try this a give some feedback.
Hello! I have MacBook Air 2022 M2 and have tried this command. Output is ok. After 30 min of testing it seems that I have feeling better. More testing is needed.
Thank you, NewDwarf!
I'm not sure anymore I hoped that it's at least better on my external display (closed MacBook) but I have burning eyes again, stiff neck etc. I guess I need whole day to test it properly.
I have MacBook Air M1 2020
mirza To get rid of PWM you need to use it above 50% brightness setting, you can use the Iris software to reduce brightness artificially (https://iristech.co) while keeping the real brightness setting above 50%
You can find the PWM test in this review: https://www.notebookcheck.net/Apple-MacBook-Air-2020-M1-Entry-Review-Apple-M1-CPU-humbles-Intel-and-AMD.508057.0.html
@insta42014 - I tried everything possible, nothing worked so far. Will try to return it to my local autorised resseler, if that doesn't work will try to sell it.
Sorry, but I didn't feel any difference, compared to my monitor which is plugged to pc, I get this immidiate pressure in my neck, sort of like this macbook display is shooting me Maybe Apple doesn't allow this to change at all. I dunno.
works something for a while, and then shows nothing, just goes to new line again
