Chapter 6 EDID Key-in Procedure Extended Display Identification Data is a VESA standard data format that contains basic information about a display device and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the P5270/P5270 Refresh 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 display device and the PC graphics adapter. The system uses this information for configuration purposes, so the P5270 and system can work together.
