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 EP7150 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 EP910 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.
