EDID Upgrade
6-1 EDID Introduction
Extended Display Identication 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 conguration purposes, so the
monitor 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.
- The EDID upgrade procedure of EP721/727/723/728 Family / EW1610 Family is
the same as EP721. Here, we take EP721 as an example.
