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.
