    laptopmedia.com do pwm reviews for android phones. I've also hear the iphone doesn't use pwm.

    It appears to be flickering bad. I was probably going to buy that. Oh well, the wait continues.

    Hi,
    this is a tablet from China small manufacturer,
    I cannot observe flickering on the screen, is that harder to detect using only camera this case?

    Just wanted to tell that I can't see any flicker on the Vaio Z Canvas at any brightness (using the camera or pen test).

    We bought this tablet a few months ago and haven't seen any signs of flicker based on the camera test, and the fact that it hasn't given me migraines.

    Hey guys!

    I hope some of you are still around to see this niche thread pop back up. copy/pasted from the Samsung board.
    ~~~~~

    From the Samsung info page...

    https://news.samsung.com/us/samsung...n-june-11-with-in-store-availability-june-26/

    "It offers a premium viewing experience with a Full-HD touch screen equipped with RealView Display, showing images at 350 nits in normal mode, and 450 nits in outdoor mode, for extreme clarity even under direct sunlight."

    How does this work, exactly? Are they using one of those seizure-inducing LED high Hz flicker modulation schemes for their "Indoor" 350 brightness setting? Or is it something more sane, like simply overall limiting the source power for the screen.

    Too bright is too bright. Is the 450 nit level eye-burning for use in a soft-lit room? Heck, is 350 too bright? Because no way am I going to be staring at a flickering light source for hours on end!

    Just checked my Fujitsu T734, which I assumed was PWM-free since my eyes never got tired after using it for hours, to a point of praising it - and woah, it actually has PWM at any brightness level below 60%. On a smartphone camera, it flickers very fast on brightness levels 0% & 10%, and quite slow on 20% to 50%. I mostly use it at 0% to 20% brightness. Didn't have any problems using X220 tablet which reportedly has low-frequency PWM either.

    Guess that makes me completely insensitive to PWM. \= I do get annoyed by overly bright displays unless in direct sunlight, though.

    The important question remains, though - is PWM harmful to people who are not sensitive to it?
