Definition: 8K TV

An upcoming generation of super high-resolution TVs with four times as many horizontal pixels as a regular 2K TV (7,680 vs. 1,920). First prototyped in 2003, this "Super Hi-Vision" technology was developed by the Japan Broadcasting Corporation/Nippon Hoso Kyokai (NHK). Samsung calls it "Super HD" (SUHD), and it is also known as "Ultra HD" (UHD), the same designation used for 4K TVs, although that moniker will likely change if 8K TVs become mainstream. Scenes are so realistic that people have experienced slight nausea while watching action movies.

By 2016, Sharp, Samsung and LG demonstrated 8K TVs in the 100-inch range with enormous price tags. However, 8K TVs have been purchased by companies for product demos and advertising.

Terabytes of Storage
In 8K TV, each 33.2 megapixel frame requires nearly 100 megabytes of storage (uncompressed). A full two-hour movie at 60 fps would occupy 43 terabytes, and a 3D 8K TV would require twice as much. Needless to say, extremely advanced compression methods are necessary (see HEVC). See 8K monitor.
