I've been messing with the HTC M8 a bit. I can't use it. I get too tired on it and I don't recommend anyone use it. I'm honestly puzzled by the statement that it can be used with no problem. I saw Gurm doesn't like it either.

It is possible it is related to the firmware version currently installed in the device. Messing about with developer adreno graphics drivers didn't change a thing, nor did a test with dropping down to HTC's version of KitKat for this. So since it wasn't the Android version, that leaves firmware and/or the panel/driver combination.

I haven't messed around with the firmware as of yet and obviously can't change the panel/driver.

Too bad, it's not a bad device, but I wouldn't recommend this to anyone on this forum.

    Sunspark which phones/tablets are easy on the eyes for you? I am looking for one which does not have PWM and temporal dithering.

      Sunspark if the e ink panel refreshes without blinking/reverse imaging too much then it will be very easy on the eyes, an ideal solution.

        Sunspark have you tried using it with grey/amber text on a solid black background? Slcd3 displays are very bright, so the less pixels turned on, the less strain on the eyes, maybe? Or is it a purely driver and panel problem?

          optix hi, any other phones you have recently come across which are ready on the eyes? Have you tried any of the Sony xperia phones?

              Gurm I have a very similar eye sensitivity problem. On the M8 what display settings are most comfortable for you? I would like to get an M7 or M8 but some readers do find discomfort using them.... any info on the Sony xperia phones? Could the Bravia engines help or make it worse? If there are any other phone displays you are comfortable with do let me know, thanks.

                  Would anyone know if any of these phones are PWM free?

                  The reviews I have found haven't tested for PWM.
                  Thank you.

                  This is what I wrote on 12th of Feb:

                  "I'm currently using HTC One M8 (the "correct" version!) and I can look at the screen for hours without any eye strain, motion sickness, nausea or general discomfort. I said "the correct version" as there seem to be two component suppliers HTC uses and while I can use my M8 normally, I can't look at my girlfriends' M8 for more than 5 minutes without discomfort. I can confirm the same for HTC One M9 - you just have to get a right version that doesn't cause problems. More details at XDA: http://forum.xda-developers.com/showthread.php?t=2705983"

                  Again, we have two M8s at home - mine is fine, I can look at the screen for 3+ hours without any strain or nausea. On the other hand, I feel symptoms looking at the display of my gf's M8 in 5 minutes.

                  So, same vendor, same model, same software, same firmware. One is OK, the other is not. I believe the only difference is obviously the display itself and controller.

                  I'd suggest one should try to find a used one locally - that way you can test it out before buying (invite the seller to a coffee and play with the phone for 15 minutes =)

                  PS: my M8 is more on a warm side compared to my gf's one, which is a bit more bluish

                      optix amazing. If the e ink screen can really handle all the apps with that refresh rate then it is definitely worth it. Thank you for posting. Will find out the price...

                        optix Wow amazing - so the e-ink screen contains no LED?
                        What sort of backlight does it have?

                            Fyi

                            optix I haven't found any reviews of the Moto X 2014 testing for PWM, or any camera tests on it. From your experience would you say it is PWM free, similar to galaxy s2?

                                I can't guarantee you that it 100% doesn't flicker at any brightness level, as I've used the phone one time for just a little more than 1 hour. During that time it didn't cause me problems and I had the brightness turned up to max. It would be the best if you could test it yourself =)

                                    optix I tried a Moto X (possible 2014 from AT&T) and couldn't see any PWM with the shake test and it felt fine at low brightness.

                                    Moto X Force (whatever that is) has PWM as confirmed here
