4K TV

A TV set with a screen resolution of 3,840 horizontal and 2,160 vertical pixels (2160p). Also called "Ultra HD" or "UHD," high-end TVs today are typically 4K TVs. With four times as many pixels as HDTV, 4K TVs use algorithms to "fill in the blanks" when displaying content lower than 4K. DVD (480p), Blu-ray (1080p) and cable TV (1080i) content is upscaled to 2160p, which provides better visual quality especially noticeable on screens 65" and above. See Ultra HD Blu-ray.

Native 4K Content Makes a Difference
Movies shot with 4K cameras are native 4K, and they will always look best on a 4K TV. Although many people find little difference between native and upscaled content, it is very dependent on the video images. Sometimes, upscaled 2K content is misrepresented as native 4K.

When 4K TVs emerged in 2012, Sony offered a few 4K feature films on a hard disk player for its 84" TVs and later offered a paid download service. In 2018, cable and satellite providers began to offer 4K set-top boxes but content is limited.

4K TV Makes 3D TV Better
In a passive 3D TV with 1,080 lines of resolution, each eye gets only 540 lines. With 4K's 2,160 lines, the full 1080p resolution is available to each eye (see 4K 3D TV). See 4K resolution, 4K upscaling, 4K pass-through, 4K monitor and 2K TV.
