DisplayID is a VESA standard for metadata describing display device capabilities to the video source. It is designed to replace E-EDID standard and EDID structure v1.4.

The DisplayID standard was initially released in December 2007. Version 1.1 was released in March 2009 and was followed by version 1.2 released in August 2011. Version 1.3 was released in June 2013^[1] and current version 2.0 was released in September 2017.

DisplayID uses variable-length structures of up to 256 bytes each, which encompass all existing EDID extensions as well as new extensions for 3D displays, embedded displays, Wide Color Gamut and HDR EOTF. DisplayID format includes several blocks which describe logical parts of the display such as video interfaces, display device technology, timing details and manufacturer information. Data blocks are identified with a unique tag. The length of each block can be variable or fixed to a specific number of bytes. Only the base data block is mandatory, while all extension blocks are optional. This variable structure is based on CEA EDID Extension Block Version 3 first defined in CEA-861-B.

The DisplayID standard is freely available and is royalty-free to implement.
