I've measured a Macbook M2 16 Pro and it has PWN that can't be turned off in any of the profiles.

    10 months later

    I have been using a mabook air M2 15" 16GB for two months now and like any other macbook I have tried in the past it causes me: migraine, dizziness and sweaty hands/hot sensation.

    I have tried disabling dithering via command string but I haven't noticed any improvement.
    Using betterdisplay removes the hand sweat but the migraine and dizziness remains. I take 5mg of fluxarten and whit this drug I can complete the work day.

    When I work from home, I connect the MBA via USBC --> DP to the LG 27GR95QE monitor (OLED 2K 240hz). With this setup I can work all day without betterdisplay and without fluxarten. I have a slight headache but totally acceptable.

    MACOS 13.5

    Edit: with the LG OLED monitor i am not able to use my gaming PC (W11 21H2 with nvidia 4070). So, as always, is a software problem.

      Lauda89 Yeah external screens are really great. Just not sure why you are not using usb-c? Are you trying to say display port somehow better for the eyes ? I personally have this macbook air m2 only for swift ios development, using external monitor.

          Could you please perform a test? Try setting the LG monitor using the MacBook Air to 720 HDPI, which is the 'retina' mode for that resolution (1440/2). Then, check if the UI rendering bothers you or not. Thank you."

              anon123 I am trying but when i select the 720P HDPI the UI became giant. Is not usable in this condition honestly..
              Am i doing something wrong?

              EDIT: maybe i can keep the 1440P resolution and activate the HDPI with the better display app?

                Donux Because the LG 27GR95QE dosn't have any USB-C port. I have tried to use a USB-C -->hdmi cable but the image quality was horrible, instead USB-C --> DP is good!

                  Lauda89 I've been pretty much unable to use any Retina displays. So I'm stuck using the last iMac and Air that Apple produced (2013 and 2017 respectively).

                  I got an M2 15" MacBook Air last month, and was fine for the first couple hours until everything started up again, mainly strained and burning eyes for me. But I might try this monitor and see if it helps.

                  Does anyone know if temporal dithering is still present if you use an external monitor with true 10-bit color?

                    Alyosha2001 Yes, this is what notebook check wrote in this machine too. So no surprises here.

                      joelj Are you still confortable with your Macbook air m2 ? And would you mind sharing your panel number and OS version ?

                          I tend to mostly use it with my monitor as I feel a larger display is less likely to give me general eye strain which I believe is more likely due to being short sighted and using screens a lot (working day and then personal projects in the evening).

                          However, the one day I go into the office, I'm able to use it all working day looking at it fine without any issues. I actually now use two MBA M2s in this set up (my personal one and my work one). I couldn't use the MBP M1 16" for short periods without feeling it.

                          I can also use it sporadically around the house without a monitor but feel this can be somewhat risky if for a long time and I've had migraines from using it in dimly lit conditions on its own/in the evening for a long period, but general with a monitor and in the day on its own seems fine.

                              joelj This monitor is very popular, it is always stocked near me in shops. But, reality is - it is 6bit + FRC. But it is better built externaly if that is important for you. BENQ PD2705Q is similarly priced, but it is true 8 bit. Yet for me M2 is clinical with external monitor too. That is why I am leaning towards failty GPU design. So far tests seam to be on my side, clearly showing higher flicker rate for anything connected to apple silicon.
