4K TV - August 4K Ultra HD TVs (also known as UHD TVs) deliver four times the picture resolution of 1080p Full HD, that's eight million pixels compared to two million pixels. That means more image clarity in terms of fine details, greater texture and an almost photographic emulsion of smoothness. 4K resolution is now being employed in an increasing basis in commercial digital cinema projection using the 4096 x 2160 pixel option, where more and more films are shot or mastered in 4K, or upscaled from 2K (1998x1080 for 1.85:1 aspect ratio or 2048 x 858 for 2.35:1 aspect ratio).
