Eye fatigue on my new ipp 10.5?

Yesterday I went to bestbuy and played with the new 10.5 iPad for about an hour. I am sensitive to flicker but I didn't have any signs of headache so I think I'm good with the new display. The only way I could tell any difference between new and old displays was during scrolling ....and I noticed the new iPad felt taller , wish they had reduced the top and bottom bezels as well.
We also need some unbiased blind test images for all to vote on which is sharpest.
Sure. But when reading it's not changing frame rate unless you're scrolling. To test the theory, just turn off the 120hz in the Accessibility settings.
That said, I don't know if that absolutely locks the system to 60hz or if it still drops. I can't tell when the system is adjusting refresh anyway. My suspicion is that any headaches are not being caused by the screen changing refresh, but more likely just the smoothness not being adjusted to by the user.
Either way, try 60hz and see if it makes a difference. If it does, I'd either try to adjust to the 120hz, or return it. It's, for me, the biggest reason to own the new iPad Pro.

This makes no sense. Real Racing is a 60hz game. The new iPad Pro is playing this at 60fps. There should be zero difference between the new iPad Pro and the old ones/older iPads in terms of frame rate.
Are you absolutely sure it's programmed for fixed 60 and not just syncing to the highest possible frame rate that's divisible by the max refresh rate with no decimal data? I.e. vsync
It's not that simple when it comes to refresh rates. Often upping the refresh rate/fps of a game beyond the target frame rate will completely break it (AI can often be a victim of high refresh rates).
I'm willing to bet Apple will never let games run over their target frame rate. That doesn't mean some games won't run smoother. For example, a game that that targets 60 frames per second will, on the new iPad Pro, hit that target more often. However, it will not go above 60 frames per second because that could potentially break it.
I've played a few games since upgrading to the new Pro and not a single game is running at 120fps.
I compared my air 2 to my 10.5. Disagree with your statement about the air 2 being more sharp.
They did reduce the top and bottom bezels from the 9.7 but sure it would be nice if they were as slim as the sides.
I recently watched the WWDC session on the improvements to Metal, and they do go into detail about how to implement frame rate targets and that, and it's definitely always been possible with Metal apps to target "maximum available display refresh rate" as your target frame rate. And in Metal 2 there'll be more options for targeting the max available frame rate, and scaling it down if it's not being reached at runtime.
You can program your render loops in many different ways, and if you do it like it was common in the days of NES and before, sure, changing the frame rate would massively impact the logic of the game too, as is obvious by how games would behave differently on NTSC and PAL systems. However, it's a best practice to do thread synchronisation to avoid this nasty stuff, and make sure that any frame rate will still behave properly.
Hi guys,
This topic was commented last year with first ipad pro:
https://www.google.es/amp/s/amp.reddit.com/r/apple/comments/4um4ef/ipad_pro_related_eye_strain/
Maybe it's related to true tone?? This characteristic is suppose to improve eye relaxing so it has no sense. I remember when I bought my first 27" imac (late 2009 model) I suffered eye fatigue the first days/weeks.
Maybe the eyes need time for new screens (including technologies that are better for them)....

I'd be sensitive to any headaches, or reduced sharpness.
Have a new 10.5 iPad Pro cellular. No headaches. No issues with true tone. No issues with scrolling. No issues with 120hz. Looks better than my iPad Air 2.

Had you read this thread before you played with it though? Placebo can be a very real phenomenon. We need blind testing. Someone who's never heard about there being potential issues or anything doing extended use and then, without being asked if there were issues, telling about the experience.
The key is here is max frame rate target. In any case, no games yet are running at 120fps as far as I'm aware, and I've tested a bunch since posting here. Be interesting if anyone feels like there are any.
Well, I think that you'd probably need to recompile the code for iOS 11 before it would run at 120, even if the code could function at 120 (Talking specifically about rendering with Metal/OpenGL, and not apps using standard system APIs and Interface Builder objects). Or perhaps not iOS 11, but at least declaring the iPad Pro as a deployment target.
Regardless, if you do thread synchronisation "properly" max frame rates shouldn't be a problem. There's a reason why there's no problem with GPUs running things like Counter Strike at 300FPS, and people displaying it on 144hz monitors, or even overclocked monitors going above that. (And I now that's just one example, and there are cases where frame-rate limiting does matter to the logic of the game too, and going beyond it could introduce unexpected behaviour, artefacts or crashing, but I'm saying it's definitely possible, and I'd even say more common, to create frame rate independent games).
In my case looking at the same content side by side my air 2 has the better looking screen.
please update if you find a solution to the eye strain. I'm reluctant to sell my air 2 and get the pro. Maybe placebo, but messed with the 10.5 today for about 20 minutes and noticed it. I wish the current 9.7 non pro had the laminated screen and the extra speakers, for my uses that is all I really need.
Are you comparing native apps like Safari? Remember that games etc should look slightly sharper on the Air 2 until they are updated to support the new 10.5" resolution.
Then that's very odd. Maybe something is messed up with that particular iPad? Can you compare with a second 10.5"?
Yes, it is a valid concern. I gave my 10.5 ipad to my teenage son to try for a couple of hours. After an hour, he gave it back to me saying it was too hard to read. He didn't talk about a headache, but he said text in kindle books and on web sites is difficult to read comfortably. Felt like his eyes could not focus properly.

Have you tried decreasing the brightness? The iPAD can only give me eye strain if I don't do that. And I change that setting for the entire day, not just during the night.
