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.
