The highest-resolution TV set in production. An 8K TV has a screen resolution of 7,680 horizontal and 4,320 vertical pixels (4320p). Advertised as 8K Ultra HD, it has four times as many pixels as a 4K TV (2160p). It uses algorithms to "fill in the blanks" when displaying content lower than 8K, which is almost always.

Prototyped in Japan as early as 2003, Sharp, Samsung and LG demonstrated 8K TVs in the 100-inch range in 2016. Such TVs are used by companies for product demos and advertising. However, in 2018, Samsung debuted an 85" 8K TV for home use.

Why 8K When There Is No Content?
There may not be 8K content commonly available for many years, if ever; however, there is value in 8K today. A large 8K TV is much sharper because all TV screens have the same number of pixels. For example, a 75" 4K TV has the same eight million pixels as a 32" 4K TV. The pixels are bigger on the larger 4K set causing the image to be less sharp. An 8K TV upscales 2K and 4K content to fill in the 33.2 million pixels on the 8K screen, resulting in a much less grainy image on very large screens.

Terabytes of Storage for 8K Content
Each frame of uncompressed 8K content requires nearly 100MB of storage. Thus, a full two-hour movie at 60 fps would occupy 43 terabytes. Needless to say, extremely advanced compression is necessary for 8K content (see HEVC). See 8K monitor.
