My personal dream: 4K projector with 10,000 lumens, 50,000:1 contrast ratio, 105% NTSC color gamut, LED or Laser light source (50K hours lifespan and low power consumption) 2.35:1 native aspect and a 60° or wider projecting angle, so it will work with large screens without having to be more than 10-12′ away from the screen.

In reply to Fabio Fumi. You are mistaken...!! It is correctly 4 times as much data (2 x 2 = 4 as 3840 × 2160 both are exactly twice of 1080P).

Mhh … the scaling from 1080p to 4K for file size, or Kbps for streaming, that you did hasn’t convinced me… You made a x4 multiplicatin, but moving from 1080p to 4K the pixel count is not 4, but about 16 times, I think. So is (more or less) the byte count, before and after compression. Isn’t it?
