Now we just need monitors, rather than projectors, that can actually display 4K content at its native resolution. Every LCD panel I've seen tops out at 2560x1600.
native resolution of 3840×2400 pixels (WQUXGA) on a screen with a diagonal of 22.2 inch (564 mm). This works out as over 9.2 million pixels, with pixel density of 204 pixels per inch (80 dpcm, 0.1245 mm pixel pitch)
Quad HD 3840x2160 prototypes have been shown, so we're getting close. Once 3D becomes a standard feature, TV makers may have to adopt quad HD to keep margins up.
I've got a 2560x1600 monitor, and honestly, the 4k video looked worse to me than 1080p. Blocky all over the place. If they can't raise the bitrate on the 4k videos, there's really no point to it.
