A system and method for communicating DisplayPort information is provided. The system includes: a local unit comprising a local controller operable to produce a request packet in response to a DisplayPort request received by the local unit from a DisplayPort source unit and to transmit the request packet to a remote unit of the system via a first simplex channel of a dual simplex communications link; and the remote unit comprising a remote controller operable to produce a reply packet in response to a DisplayPort reply received by the remote unit from a DisplayPort sink unit and to transmit the reply packet to the local unit via a second simplex channel of the communications link. The system allows distances between the source and sink greater than otherwise possible under the DisplayPort specification, and can communicate DisplayPort and non-DisplayPort signals via a variety of types of communications links.
