Data) information of the attached video display. It stores and recalls a default EDID
settings in non-volatile memory allowing your computer boot directly from EDID
read/write. It can also read and store the EDID of your display and even let you
modify the EDID and upload the modified EDID to displays.
*Extended Display Identification Data (EDID) is a standard data format that contain
basic information about a monitor 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.
Introduction
The information is stored in the display and is used to communicate with the system
through a Display Data Channel (DDC) between the monitor and the PC graphic
adapter. The system uses this information for configuration purposes, so the
monitor and system can work together.
