Display resolutions

The computer industry has developed a series of display resolutions which span television’s SD, HD and UHD, a selection is listed below. The availability of hardware to support these resolutions has, and will continue to benefit television and digital film.

All use square pixels and none correspond exactly to television formats so attention to size and aspect ratio is needed when using computer images on TV and vice versa.
