DDC (Display Data Channel)

DDC is a communication channel for displays and computers. The DDC feature allows the monitor

controller to be automatically configured to make optimal use of the display without manual user

interaction. DDC is implemented as part of the new Plug & Play approach introduced into the PC

market to increase user friendliness.

The three levels developed for Plug & play are: (1) DDC1, monitor send data to the PC; (2) DDC2B,

PC can request information from monitor; and (3) DDC2Bi which is a two-way communication -

monitor can be addressed and PC or graphics board can give commands to monitor.
