I bought a Macbook air M1 and the first day or so had a strain, but now i dont have a problem. Ive been looking at the new iMac and instore that seems fine to me. I cant use Windows 10 because of the eye strain/headaches so this may well be my replacement for my 7 years old Windows 8.1 machine.

The more I read about dithering for color, the more I feel this is a very overlooked issue.

Check this page out regarding temporal dithering and look at the very slowed down image and see if it makes you feel weird. Please also read their data.

It is my belief that dithering is used for HDR. I'm still trying to verify this. If so, this explains why all of the current TVs are out of my reach.

    I think the HDR "certifications" only "mandate" that displays are native 8-bit, all else is kind of "ad-hoc", but I could be wrong. ๐Ÿ˜

      Thanks for that. I will need to see what the full requirements are and what manufacturers do to meet them.

        Off the top, the color gamut could be where dithering is used as a trick? Iโ€™m firing in the dark here.

        Their example with the GTX 1650 further confirms our finding here that newer Nvidia GPU always dither, even when dithering is turned off in Nvidia settings on Linux. They say itโ€™s likely due to a driver bug. Iโ€™m pretty sure this communities suspicion that itโ€™s set to always dither in the vbios is more correct.

        I was reading (here possibly) that AMD cards may have more direct ways to disable dithering. If I find this to be true, I will be building a full AMD PC here soon. Iโ€™ve wanted a good excuse to upgrade, but this would be a very good reason to do so.

          Clokwork Just a heads up. I've only confirmed that's the case with the Radeon Pro W55500 under Linux.

          I haven't completed my testing, but I have reason to believe other Radeon cards may not be okay for dithering.

          I'm noticing big issues in OS versions on Mac devices. It has nothing at all to do with dithering

          Apple deciding to use temporal dithering from here on out 100% excludes me from their lineup. Somehow my iPhone X works for me. Seems it will be my last i device unfortunately.

            Clokwork Mee too! The Iphone X is one of the best device i've ever had. Zero eye strain..
            Honestly i've never tried other recent iphone, but next year i will try to change it.

              It's odd that the X works for you guys, I wonder what makes it different than the later OLED iPhones. The X was extremely harsh on my eyes, just like the 11, 12, and 13.

              Do either of you have issues with any of the modern iPads or Macs?

                I absolutely do. All of the new products with screens that apple makes currently are unusable for me. I wish I could get apple to confirm, but I am close to 100% certain my issue is temporal dithering. This is the only common factor I have found across displays I have issues with. PWM doesn't bother me apparently according to what I use currently.

                  Clokwork Consider emailing accessibility AT apple.com. If enough people do it, they might take this seriously.

                  Apple spends a lot of time to develop VoiceOver screenreaders for blind people. That's a minority of the population, like us. We need to make Apple care by letting them know this issue exists.

                    ryans I think I have put my name in that hat already, but did so with no expectation. I can't imagine them taking it seriously, but I am a pessimist when it comes to Apple and this issue. I will try again just to make sure.

                    I've never tried the iphone 11, 12 and 13 so i can't reply.

                    I am using also the pixel 4A and it's fine for me.

                    Recenter Apple product that i've tried with bad results are:

                    • Ipad Pro 10,5" (i am still using the ipad air 2)
                    • MBA 2018
                    • MBP 16" 2019

                      Donux Can you please share the EliteBook model that's usable for you?

                      Donux lower pixel density

                      Hi, out of curiosity, why lower pixel density?
