The human visual system has a limited ability to discern improvements in resolution when picture elements are already small enough or distant enough from the viewer.
At home-viewing distances and current TV sizes, HD resolution is near the limits of resolution for the eye and increasing resolution to 4K has little perceptual impact, as consumers are beyond the critical distance (Lechner distance) to appreciate the differences in pixel count between 4K and HD.
The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840×2160 pixels.

I don't understand how LG could have released the product in this state.What struck me as strange is the lack of apps that are available and the revelation that my player can recognize youtube videos in HDR, but my TV can't. Another annoying problem is that it would occasionally show black screens for a second or two at a time while playing a movie. No update for Netflix App not usable at this point. No zoom function Literally just a basic player that happens to play 4K & 3D discs.
