Just curious: how are the 2020 iPad Pros in terms of eye strain/headaches? I see from notebookcheck that they’re using PWM now, has anyone noticed any discomfort from the flickering?

Comparing to the 10.5 Pro (2017), which I recently traded in for the 11” 2020 IPP, no, I don’t feel any eye strain. On an average, I use the iPad for 5-7 hours a day.

Thanks for replies, it’s encouraging to hear that it’s not causing any issues.
I thought PWM only happens on OLED displays?
It’s most commonly found on OLED displays, but it can apparently be used in LCD ones as well. I was kinda surprised to see it in the Pros tbh.
The strain happens mostly when you look at your receipt for too long.
Well, you aren’t wrong... 😅

While I appreciate notebookcheck's efforts here, what they've detected is not PWM. The frequency they've measured is so low it could be easily found with a cell camera.

I think its not only from PWM, i had the iPad Pro 2018, the new iPad Air 4 and for my Company i buyed a Pro 11 from 2020. On all iPads i had Eye Strain and the iPad Pro 11 from 2018 and the new iPad Air 4 from 2020 dont have PWM. On the old iPads released before 2018 i dont have any Problems. I dont know but i always had the feeling with the new iPads that they are too bright and the LCD Panel is blinding me, True Tone on or off doesnt make a difference for me.

I know its an older thread but there definitely is an issue for me with the 2020 iPad pro 11” causing severe eye strain. I don't know what it is but I may have to discontinue use of it. I went back to my old but still working pro 9.7” for now.

I have the 2018 11" iPad Pro and iPad mini 4 and I don't feel PWM issues. I do find it more comfortable to read on my mini 4 due to screen size.

As for PWM, I'm not quite sure if I'm sensitive to it or not. I was briefly into flashlight hobby, and the one and only flashlight that uses PWM to control brightness that I have...I always got headachy withing a minute or two when checking out the beam from that one flashlight. All my other flashlights are current controlled brightness so never had headache from these other ones.

Never had any issues with any of my iPads and my 2020 11” Pro has the best screen on an iPad ever :)

If one is getting eye strain with the Ipad Pro 11, try turning off Face ID and see if this helps. The scanners cause some people eye strain like my self, so i turned it off on my 12 Mini and get no issues.
I may try that. It’s been a week since I’ve used it and my eyes have recovered.. they were really sore. I’m running out of time to return it from I bought it also.

Sorry for resurrecting an old thread (not sorry), but I just returned my 2021 iPad Pro 11. I was using a 2017 iPad Pro 10.5 previously for years with no issue. With the new pro, even for just a few minutes, I felt pretty bad vertigo, focusing issues, and fatigue.

Side by side, I played the same video on each. Something about the new pro made it hard to focus on the screen. It felt like my brain was being fed too much information.

this happened to me last year when I bought an LG OLED. I returned it for the same reason. I’m fearful I can’t buy any new tech due to these displays or tech driving the displays.

I would say try it again if you don't mind. They are using pwm to control the backlight. It takes at least two weeks or a month to get adjusted to it and in the meantime it can be feeling like you’re going to die. Your eyes will adjust like other people’s and you’ll be able to use it without any problem. In other words no more pain. Use your old one and then the new one and go back and forth for awhile eventually switching to the new one only. It will not cause eye damage or Apple and Samsung and LG would’ve been sued already.

Sorry but there are many who are PWM sensitive, including myself, who have found that the eyes just dont adjust to it. And why put yourself through days of pain and headaches anyway. I have a job to hold down and if I had eye pain and migraines that wouldn't be possible.

I went to the eye doctor and he found no issues or disease in regards to my eyes. It’s sad that I hoped he would find something to give me an explanation.

I ordered a 2nd iPad Pro 2017 just to be safe in the case my current one dies. As long as the normal Retina display (not liquid) is around on the base iPad, I should be fine but I feel it will be antiquated soon.

There has to be some key difference(s) between these Liquid Retina displays and the previous retina. I have no idea what it is.

PWM?
Dithering for color?

Anyone have any experience with the 11" 2021 Pro? I asked the notebookcheck staff if there was any flickering at all on the 11", and got this reply:

"Short answer: No, no flickering!"

The 12.9" Pro hurt my eyes, so I'm hoping the 11" would be usable.

With no PWM on the 2021 11" the outstanding query will be regarding the liquid retina and dithering.

Is it proven there is no PWM? Or is it hearsay? If I still had mine, I would perform the camera check.
