Extended Display Identification Data is a VESA standard data format that contains basic information about a monitorand its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the monitor name and serial number.
The information is stored in the display and is used to communicate with the system through a Display Data Channel (DDC ), which sites between the monitor and the PC graphics adapter. The system uses this information for configurationpurposes, so the monitor and system can work together.
The latest version of EDID (version 1.3) can be used in CRT displays, LCD displays, and future display types because EDID offers general descriptions of almost all display parameters.
