I've never heard of headaches from 24fps video , must be rare

I'd never heard of it growing up in the era when that's all there was. I don't know if it's rare, but it's only in the last decade or so I've heard people complaining about it.

We don’t perceive all types of screens in the same way. Film projectors and CRTs display parts of the frame, only part of the time. TFT and IPS screens introduce a lot of inertia and blend the frames. Both of these help the motion illusion. OLED on the other hand has the harshest frame transition - it displays the entire area for the entire time and switches frame content almost immediately.

I grew up in the same era, and I definitely knew people who could not watch TV because it induced headaches in them.

I get it too. I visually see tearing / juddering on most video lower than about 40FPS and it’s incredibly tiring.

Afaict it’s a kind of migraine. Everyone I know that gets headaches from low fps also gets migraines.
