Can the iPhone 13 ProMotion 120hz display cause dizziness?

It’s actually comical that apple recommended Katana~Sans’ response . The dizziness your experiencing in reference to switching to the 13pro max has to do specifically with motion sickness caused by the Pro Motion 120 hz display. This is due to the increase in the processing of frames which almost makes your screen look like it’s “moving” . In better terms your screen is able to process at a rate that is so fast it creates the illusion of the screen actually being in motion because it can scroll at a faster pace, tricking your eyes into thinking your in motion. However your not and that creates a motion sickness including many symptoms such as dizziness, Nausea, headaches and even eye strain. (especially when done for long periods of time)

• good example of this is 3rd person video games like Call of Duty or Fortnite when you perform motions such as looking left and right your eyes are following these motions in time with your movements in game. over long periods your eyes begins to adjust more and more to that platform and begins to identify with this image as you being present in the game. If you play these high intensity games for hours on end ( especially on high sensitivity and high resolution) you will begin to feel nauseous, because it thinks your performing these constant motions but your body is not detecting actual movement. This constant motion can overwhelming for some to process especially for long periods of time, therefore you become Become “sick” as a result.

• The same goes for a phone screen that is refreshing at 120 hz per second. A good example of when this motion can be seen best is If you scroll lightly in one sweeping motion and let the screen come to a stop on its own. You can see from that alone that “movement” I’m referring to where it looks as though you can actually see the screen in motion. It actually gives you the impression of it being in motion in the direction you choose to scroll. You may notice that on other displays this longer slowdown as it comes to a complete stop after scrolling is shorter whereas on the Pro Motion display (clearly stated in the name) it moves in at a more “ real life “ speed/fashion giving your eyes the illusion of motion your not action performing.

IN ORDER TO DISABLE 120HZ refresh rate on iPhone 13 Pro/Pro Max

-Go to settings

-Accessibility

-Motion

-Turn ON limit motion

you will notice that when you swipe up to switch between apps you previously used it does not do a motion but instead flashes straight to showing you other apps you already have open. Other motions will be limited as well

if that is NOT enough and it still gives you motion sickness or you want the motion to remain but still want to reduce the frame rate you you can turn ON Limit frame rate which will reduce the frames to 60hz. Although this completely removes the purpose of using the Pro Motion feature with the 13 Pro/Pro Max I would rather you remove this additional feature than be sick just from simply using your phone.

Also I suggest reducing screen time and brightness. The longer you use the phone in 120hz the more likely you are to develop motion sickness and using higher brightness will only create more clarity to the screen(therefore faster motion sickness). Hope this helps!
