EDID overview

Extended Display Identification Data, or "EDID", is the metadata between display and GPU.

What is an EDID?

An EDID communicates metadata about manufacturer specifications and data for a display to a video source such as a graphics card. EDID allows for the display to relay its capabilities, such as its native resolution, to the attached source, and then allow the source to generate the necessary video characteristics to match the needs of the display.

For more information on the standard for the EDID format, please visit Video Electronics Standards Association (VESA).
