4K resolution

Approximately 4,000 (4K) pixels of horizontal resolution in several digital formats for shooting motion pictures as well as scanning 35mm film into digital. 4K movies are used intact for cinema theater projection as well as 4K TVs. For Blu-ray and cable/satellite TV distribution, they are scaled down to 2K (1080p). For example, Blu-ray discs "Mastered in 4K" means the source material was in a 4K format. See 4K TV, 4K 3D TV, 5K monitor, UHDTV, DTV, aspect ratio and digital cinema.
