EDID Introduction

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 model 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 unit
and system can work together.
Note:
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.
