In my testing no, the MacBooks are fine. It’s the phones that are a problem. Easiest way to tell is get a camera app you can set the shutter speed to 10,000 fps

In my testing no, the MacBooks are fine. It’s the phones that are a problem. Easiest way to tell is get a camera app you can set the shutter speed to 10,000 fps and point it at a screen. If there are black lines across the screen there is a PWM issue. The thicker and darker the black lines the worse it is.

- vitaflo 1y agoThe latter. But it’s the preview you’re looking at. You’re not actually taking a photo.
- bmacho 1y agoA camera app can't set a phone camera to 10,000 fps. So the question is what does it do?
- bayindirh 1y agoDue to rolling shutter, you take a “progressive” photo. As a result, if the screen flickers during that time, you see this change in light intensity as horizontal bars. Thicker bars means a lower PWM frequency, hence lower quality light/brightness control.
- leakycap 1y agoI think it varies by model. The 14" & 16" MacBook Pros with the miniLED give me and many others PWM issues. On the other hand, the MacBook Air models with the notch don't seem to bother most people.
