Any Headaches/PWM Problems on new Macbook M4 Pro 14inch?

[TMan19]

Hi everybody!

I'm looking to buy a new macbook and was thinking of going with the Macbook M4 Pro 14inch. However I want to make sure that it doesn't have a strong PWM output that would bring headaches/swift eye strain. I have a Macbook Air M2 which I've read has no PWM problems + I haven't had any problems, but I need to upgrade for my Music College. I bought a M3 Macbook Pro 16inch in June and had to return it in 2 weeks because of migraines from the screen that would come in less than 15 minutes. (No its no blue light, I've never had the issue on other computers, just to say for the people that will say its that.)

Thanks for any help!

None for me. Such issues seem to be different for each person. Thus, none of us can really answer how you will be affected. Buy it, try it. If you have a problem return it.

All the miniLED displays Apple uses have a high rate of PWM and amplitude. Check out Notebookcheck for the full review.

No. but there are scratches and dents coming out of the factories in the screens. You can see them when using a flashlight and dark room.

No issues here. 14" Macbook Pro with the M4 Pro chip and a nano-texture display.

Ok so Apples Mini LED displays use PWM for dimming? That's interesting I thought only OLED screens use PWM.

That is correct and even the normal display of the Mini 6 & 7 have PWM under 10% brightness as reported by Notebookcheck. Pretty sure all these OLED displays from Google and Apple use Samsung panels as all these manufacturers have similar frequencies. Additionally, previous reports have Samsung producing the iPad Pro 11" panel, which makes me want to vomit, and LG producing the 13" version which is a tad bit better but ruins me after a half hour or so.
