i) what are the real differences for day to day usage between 60 hz and 120 hz display. Which is good on eyes

ii) When pro motion display set to 60 hz on 15 pro max , is 15 pro max display equal to that of 15 plus or is 15 PM display superior in any way ?. Please advise

I wear glasses and it makes a huge difference for me. The scrolling is just infinitely smoother, makes my eyes less jaded, especially in low light. I came from a 60hz iPhone 13.

Always on display and 120hz are the only differences between the two phones from what I understand.

I have SE 2022 (60hz) and a 13 Pro (120hz); either is fine and ProMotion is not a big deal to me, though I can see easily see the difference. I wear glasses too, like Risco, but only for distance and not for reading/using my phone or computer.

Limiting my 13 Pro to 60hz via Settings/Accessibility/Limit Frame Rate or Low Power Mode looks worse than the 60hz native on the SE 2022. Compared it to my sister-in-law's 14 non-pro, and it (my 13 pro in 60hz mode) looks worse, too. I'm not sure why..? 🤷🏻‍♂️

PWM under low frequency hurts eyes badly. Plus the benefit of smooth animation and scrolling is hard to miss.

Shirasaki, so does a screen with 120 Mhz have less of a chance to induce PWM symptoms like headaches etc.?

There are many comments in the mega Eyestrain Thread, where people had to turn off ProMotion because it gave them either headaches or motion sickness

A 120hz phone slowed to 60hz in software looks worse than a phone with a native 60hz screen in my experience.

Thats why people selecting the ‘reduce motion’ option on a promotion display think 60hz is a lot worse than it really is.

Yeah, I don't quite get. I have an iPad Pro with 120Hz and a iPhone 12 Pro 60Hz and I absolutely don't notice the difference in my daily use. Even toggling back and forth. Maybe I would, if I compared side by side, but to me, it feels a bit like when 3D displays were pushed as the next big thing, though I do believe high refresh rate will stick unlike 3D. It is just not a factor for me and something I consider upgrading to get. Maybe I am just too old and don't use my phone in ways where it matters, I don't know.

It’s a night and day difference for me, so much so that I wouldn’t consider a 60Hz display now. I’ve got an iPad Pro and 14 pro max and if I ever have to use the wife’s IPad or iPhone 13 the difference is massive. obviously used 60Hz displays before and thought they were fine. Just for me, once I’ve gone 120Hz there’s no going back.

PWM in essence changes LED duty cycle to achieve brightness control. The higher the frequency is, the less noticeable LED blinking is to folks, which can help easing the eye strain.

native 60hz has less problems and will last longer, better battery etc..

I’ve had my iPhone 15 Pro for 8 days now, coming from an iPhone 11. So this is the first phone I’ve had with 120hz display. However, for me, I couldn’t discern any difference between the 120hz and 60hz, so I’ve turned the 120hz off.

it’s weird isn’t it, my wife’s the same, even with 2 devices next to each other, 1 at 60Hz and the other at 120Hz she swears she can’t tell the difference yet to me the difference is massive. I’m sure smarter people than me know why.

It’s kind of like 1080p vs. 4k: You definitely notice the difference, but it’s not like 1080p is unwatchable. We’re all a little spoiled with quality at this point across the board, none of it is bad. Our brains will adjust to 60hz or 120hz quickly, the faster refresh is just a nice-to-have thing.

For me ProMotion makes every input look super smooth. I saw my friends iPhone 12 Pro and I thought there was something wrong with his phone. It was so choppy and looked like it was dropping frames. That’s when I remembered it was due to ProMotion.

Scrolling on a 120Hz display is very pleasing to the eye. You’ll feel each swipe of your finger feels ultra responsive, along with the 120Hz touch sensitivity, you’ll get the feeling that your phone is very responsive.
