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: The FW upgrade procedure for PK301/PK320/PK301 PLUS are the same,we take
PK301 as an example here.
