EDID Upgrade

6-1 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. 

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.
