"Ultra HD" Replaces "4K" as Official Next-Gen TV Name

- Ultra High Definition screens and projectors should have a resolution of at least 8 million pixels, with at least 3,840-pixel-by-2,160-pixel resolution.

- The screen aspect ratio should be 16 by 9.
那21：9是要去仆街嗎?

- Perhaps mostly importantly, the set must have a digital input "capable of carrying and presenting native 4K format video ... without relying solely on upconverting," the CEA said.
