The next level of HiDef TV will be called Ultra High Definition.
That’s the name the Consumer Electronics Association has given new displays offering four times the resolution of current HiDef TVs, or 4K, as it has been known thus far.
The group also defined the minimum performance attributes for Ultra HiDef, including display resolution of at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically. Displays will have an aspect ratio with width to height of at least 16 X 9. To use the Ultra HD label, display products will require at least one digital input capable of carrying and presenting native 4K format video from this input at full 3,840 X 2,160 resolution without relying solely on up-converting.
