8K standard

8K is a Digital Cinema Initiative(DCI) designation for the horizontal resolution of high-definition displays. 8K is equivalent to 8,000 horizontal pixels.

Due to the different aspect ratios used in video/ television display and cinematography, the horizontal resolution values for the 8K standard can be above or below the 8,000 pixel horizontal resolution. For example, the horizontal resolution for Ultra HDTV is 7,680 pixels, which is double the 4K standard of Quad-Full HD with 3,840 pixels. The vertical resolution is 4,320 pixels. This standard is also called Ultra High Definition UHD-2 or Super High Vision (SHV). The 8K display thus consists of over 33 million pixels.

There are only a few digital interfaces that support the 8K standard with the required data rates of 25 Gbit/s and more. Some work with lower refresh rates, lower color resolution and simpler color subsampling, and use artificial intelligence techniques to make the image more contrasty and sharper. DisplayPort 1.3 is one such display interface for 8K, superMHL and HDMI 2.0 others.
