What resolution is considered Ultra High Definition (4K)?

Explanation:
Ultra High Definition refers to a resolution with about 4,000 horizontal pixels. In consumer devices, the UHD standard is 3840 by 2160, which gives a 16:9 aspect ratio and four times as many pixels as Full HD. This is why 3840x2160 is the 4K you’ll commonly see on TVs and streaming. The other options aren’t the typical consumer UHD format: 4096x2160 is cinema-wide DCI 4K, not the standard used for home displays; 1920x1080 is Full HD; 2560x1440 is Quad HD. So 3840x2160 is the UHD 4K resolution.
