iPhone 13 Pro Max iPhone 13 Pro Max cause me headache

[Jclok]

Update: I have been able to pretty much move past my issues on the 13 pro. I'm mostly able to use the phone normally now, sometimes a very slight headache. I am not sure if my body just eventually adjusted to the screen, or other factors changed, or a combination. I'm not sure if the issue was truly PWM, or some other issue(s). I was definitely getting very uncomfortable burning behind eyes/migraine symptoms on the 13 pro initially, as well as on the 12 pro and 13. X was fine.

Over the last few weeks I tried gradually push my discomfort daily by using 13 Pro to just expose my body with the intent to hopefully create adjustment. When it went beyond mild discomfort, I backed off and went back to my old phone until I felt OK. I don't know if this was medically wise and I don't necessarily recommend it, but I tried it. I also made some other changes, such as cutting way back on caffeine and trying to reduce stress/anxiety.

Anyway, just wanted to share my update, as I would have liked to have seen such an update from others before when deciding how to proceed myself in this situation.

This doesn’t sound like a win to me . I can’t use any new apple mobile products. They all give me vertigo. I am forced to get a surface pro when my iPad Pro 10.5 dies. I’m not entirely sure it’s the physical displays fault, but anything with the Liquid Retina or XDR name on it is a no go for me.

I have a hypothesis that there are too many forms of flicker going on with the new phones specifically.
- 480 Hz PWM
- Temporal Dithering to achieve color
- Varied refresh rate (though not flicker)

The amplitude of flicker on the 13 Pro OLED is quite significant as compared to the X. I have an expensive tool to measure flicker.
