EDID Update
EDID Introduction
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 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 display device and the PC graphics adapter. The system
uses this information for configuration purposes, so the monitor and system can work together.
If a display device has digital input ports, like DVI or HDMI, but without EDID in its Main Board, the
display device will show no image while the input source is digital signal.
