General Product Specification
2.3.3 DDC/CI
DDC/CI (Command Interface) specifies a means for a computer to send commands to the monitor, as well as
receive sensor data from the monitor, over the bidirectional link such as DDC2Ab/Bi/B+. Specific
commands to control monitors are defined in a separate Monitor Control Command Set (MCCS) standard.
DDC/CI monitors are sometimes supplied with an external color sensor to allow automatic calibration of the
monitor's color balance. Some tilting DDC/CI monitors support an auto pivot function, where a rotation
sensor in the monitor enables the operating system to keep the display upright as the monitor is moved
between its portrait and landscape positions.
The following DDC/CI commands should be supported via command line:
