Does this also affect Macbooks?

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.

  10,000fps, or 1/10,000 of a second? Asking because I don't have a Phantom at home.

    The latter. But it’s the preview you’re looking at. You’re not actually taking a photo.

      A camera app can't set a phone camera to 10,000 fps. So the question is what does it do?
      - bayindirh 1y ago
        Due 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.

  I 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.

    I have an Air and agree these are great for people sensitive to PWM like myself.

      Yes, the Air with the notch (M2, M3, M4) is specifically PWM free. There is some sort of display issue with the "OG" M1 Air screens for many.

Yes, some MacBook models are affected. The MacBook Air displays with the notch do not have PWM and do not seem to bother people. The 14/16" Pro models seem to be quite bad for most people (I had to return my new 14" model, it was rough). The first PWM MacBook I bought was the 16" MacBook Pro from 2019 (the last Intel model). I'd had a 2018 MBP 15" and couldn't figure out why I just couldn't stand looking at the new 16". I thought I had a bad display but ended up learning about PWM.
