Ultra HD

Much like the term High Definition describes video at 720p or 1080p resolutions, Ultra High definition (Ultra HD or UHD for short) is a term that refers to two video resolutions: 8K and 4K. These terms actually describe the horizontal resolution of the video image, which are on the order of 8,000 and 4,000 pixels. Average consumers have heard very little about 4K or UHD because content produced at this resolution is still in short supply, and the television displays that support it are not yet ready for mass consumption. In 2013, DivX Converter introduced two 4K profiles, which made it easy for anyone to convert video to DivX Plus (H.264) 4K or DivX HEVC 4K, and introduced a device certification program targeting Ultra HD displays.
