I have been trying to find an iPad to use that will be comfortable, for longer browsing sessions since my iPhone 13 Mini gives me some eye strain due to pwm.
I tried an iPad Pro 11”, with the m2 chip. it wasn’t bad- no real eye strain, though I’d occasionally get dry/burning eyes.
I picked up 9th generation iPad, due to the very low sale price ($250), and the fact that besides no pwm, it does not have P3 colors, so no temporal dithering. this one started off ok- only occasional dry eyes. But after a few weeks, it’s like a sunburn on my eyes each time I use it.
Last year I tried the 10th generation iPad- Sam’s specs with no p3 colors, so no temporal dithering and no pwm- but the burning dry eyes were immediate, from day 1.
Same goes with Air 5th generation that I tried last year- the effect was immediate from day 1.
sweat I’m finding of course is that the dry, burning eyes occur with or without temporal dithering- and without pwm being in the mix.
I am at a loss as to what these displays do that can cause this particular symptom, when there is no flickering?
I can use my Dell Latitude laptop for work all day long with no issues, so some led displays are clearly no issue.
I don’t expect a diagnosis of my particular situation, but I’m curious if anyone knows the technical details around what might be different on these iPad displays vs other devices that make them a potential problem for some people.
