Plug & Play DDC1/2B Feature -

This monitor is equipped with VESA

DDC1/2B capabilities according to the VESA DDC STANDARD. It allows

the monitor to inform the host system of its identity and, depending on the

level of DDC used, communicate additional information about its display

capabilities. The communication channel is defined in two levels, DDC1

and DDC2B. The DDC1 is a unidirectional data channel from the display

to the host that continuously transmits EDID information. The DDC2B is a

bidirectional data channel based on the I²C protocol. The host can request

EDID information over the DDC2B channel.
