Display Data Channel (DDC)
To make installation easier, so long as your system supports the DDC protocol, the monitor
is able to plug-and-play. The DDC is a communication protocol through which the monitor
automatically informs the host system about its capabilities; for example, supported
resolutions and corresponding timing. The monitor supports the DDC2B standard.
