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 :)

There's an e-ink display tech (just published in Nature, so very much in the lab) that has a pixel density >25,000 PPI and it can operate at up to 200FPS. It's on a scale where 1 pixel to 1 retinal cell is possible.

The color gamut isn't as wide as sRGB but it's 100x the gamut of color electrophoretic displays ('e-Ink', like in the Kindles).
