for example: A 48" 4K display is indistinguishable from a 1080p display past 2 meters or so.
this is false. there is a circling false graph that seems to claim that, however the graphc is incorrect because it assumes we are using only small part of our vision to see the screen. it also worth mentioning that our concetration point (whithc shifts around hundreds of times per second btw, our eyes move like crazy) has up to 457 megapixels resolution. thats over 21000p on only our focus point. so the whole "you cant see 4k on small displays" is pure bullshit.
Our eyes don't see in "megapixels", the limit to what we can see is determined by its angular resolution. Which, for the human eye, is about ~1 arc minute (1/60th of a degree), slightly more or less depending on individual vision acuity.
At 200-250mm, this means that the smallest objects we can see are around 50-70 micrometers.
Resolution suffers from diminishing returns, though, just look at 1440p and 1080p ~5.5" smartphones.
We can't appreciate a difference in resolution between those displays. Although the moment a dead or stuck pixel presents itself, we tend to notice it.
That's why 4K displays are, for large TVs viewed at distances between 2-3 meters, for the most part worthless.
But this is a thread about framerate, not resolution.
