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 :)

If my quick calculations are correct, the 70 inches screen at 1080p has a pixel size of about 0.7 mm give or take, where 4k would be about 0.1-0.2.
0.1mm is a smallest size of a thing a human could potentially see under very strict conditions. A pixel smaller than a millimeter will be invisible from a meter away. I really, really doubt its humanly possible to see the difference from the distances a person would be watching tv.
The thing is, the newer 4k tvs are just built better, nicer colour contrast, more uniformed lighting, clearer glass, and that might be the effect you’re seeing
Uh… Hol up. So if we can maybe see down to 0.2 mm and the 1080p screen has 0.7 mm pixels… That’s pretty much what I’m saying. 1080p is noticeably grainy.
The text in 4k looks crisper. I concur I can’t count individual pixels, but reading game menus in 1080p feels rougher and makes me squint. Reading in 4k feels more like reading on print paper or a good e-eeader.
This and yes, the build quality of newer screens also contributes.
