6-1 EDID Introduction
Extended Display Identication 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 conguration 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.
P7270I/P7280/P7270I Refresh/P7280 Refresh is the same,here we take P7270I for example.
