A new study published in Nature by University of Cambridge researchers just dropped a pixelated bomb on the entire Ultra-HD market, but as anyone with myopia can tell you, if you take your glasses off, even SD still looks pretty good :)

It’s the ratio of screen size to distance from the screen. But typically you sit further from larger screens, so there’s an optimization problem in there somewhere.
The optimization problem is actually the point of the study, encoded as PPD, which represents the density of a display’s pixel per degree of your eye’s field of vision. It says that any more than 53-94 PPD is imperceptible to most. You can see if your display makes the cutoff if you have the viewing distance and screen size here:
