Well? How does it look on smaller displays? (<-50 inch). People seem to have a lot of opinions but rarely read anything useful from anyone actually been watching or even better, working, with 4k displays.
I saw a 4k presentation on a 30 foot screen at NAB once that blew my mind. Sharpest, most detailed image I've ever seen, including IMAX. I believe it was from Sony.
does 4k even exist in a small screen yet? I fail to even see the need unless you really need to pixel peep a 4k source. I've seen 2k theatrical and am not impressed, it is too sharp for me, looks like a flat screen, only bigger. May as well just stay home and move close enough for the screen to fill your field of view. By that maxim, 4K can only be worse. My home theatre is 480p DLP on a 100" screen. DVD's on that look more like a film print than any HD or higher image I've seen. Personal preference.
