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.
