Sunspark Thanks. I did not notice that. I will visit the store and play with it.

In general the A53 screen seems ok, i have checked it in the various stores under different light conditions and it did not bother me. I am thinking of purchasing it and give it a try, it is the only way to know.

I will come back with after i get it in my hands.

I bought a Radex Lupin by Quarta and measured pulsation of almost every light source and display in my environment.
My iPhone Xr showed about 1-1.5% pulsation while iPhone 13 pro max about 10% the best with up to 60% at low brightness. iPhone 12 Pro Max has about 20% pulsation at 100% brightness up to 100% pulsation at low brightness levels. Surprisingly, 13 mini has the lowest pulsation at lower brightness - about 30% which is too high anyway.

I bought iPhone 12 Pro Max and exchanged display to Chinese IPS display from Incell in the nearest unofficial service. Incell has PWM - about 3.3% pulsation at about 300Hz. The display itself is good enough though it doesn't support True Tone. I feel some difference with Xr. I think that most part of that is due to the True Tone and a bit from PWM because a do not feel stress on eyes but have some feeling in the brain.
The solution is not perfect but it's something that is usable and doesn't hurt my eyes so far. I'll update if something comes out.

    MattG good call I did this with a 12 mini that I only had for a little while. the display looked nice, the in cells are not that bad.

      MTNEYE I couldn't use that sample but I found another one from RJ manufacturer, the best from TFT aftermarket screens as far as I know. The pulsation is below 2% at any brightness and no sign of PWM. Very good color and sharpness. I couldn't turn on True Tone so far but will try in a couple of weeks when the service I went to get updated programmer version. So, I got iPhone 12 Pro Max with display of similar quality as on my Xr, finally.

      to be continued )

        On the iPhone 14 the flicker is noticeable. The iPhone 14 plus is very bad. The iPhone 14 Pro looks good to me.

        I went to the Apple Store and watched a movie on the iPhone 14 pro for like 12-14 min long. I turned down the brightness to like 10%. I didn't feel anything. So i'm going to buy the 14 pro, I hope it will stay like that

        With the iPhone 12 i get immediately headeche. Also iPhone 13 pro max with 10% brightness i feel eye strain and a headache after 10 min.

        Odd. I have no problems using my new iPhone 14. No brain fog, strain or headache. Enjoying it so far!

          Lauda89 iPhone 7 was my last phone. For a short while, I used OnePlus 6 it was also fine.

          Strange how much it varies from person to person.

            Infinite But did you try other iPhones in the middle that were not okay? Because I can use the iPhone 6S and iPhone X. I tried 13pro and 14 pro but they weren't ok! I could try the 14 too..

            I have also to change my iPad because I am stuck with the air 2! I tried the iPad pro 10.5" and I had to return it! A lot of stress 😃

              Lauda89 Yea, it's unfortunate. I'm trying to get a Macbook right now that'll work for me but I have not found one yet. I ordered an M2 Air today. I should have it by Tuesday so I will update you if you want to hear more bout it.

              14 pro was not OK in the end, but it was better than the 14 and previous models for me. With the 14 pro the headache creeps in after about 10 mins, which I think is pretty long for sensitive eyes of mine, but ofc it is not good enough for normal use.

              Guess I’ll continue to wait then.

                [deleted] did you try 10 mate pro. It is a near perfect device for me although it is 4 y old. Just saying.

                Vaggbaba then it must be configured differently somehow because the PWM is not the same on those two devices.

                I can use the Mi11 all day without any problems, couldn't last an hour with the 11 Ultra

                  markdotpeters5 Can you tell me if the settings were the same? Such as anti-flickering, resolution, refresh rate? I found that anti- flickering is cause me more fatigue.
