Patent ID: 7937501

Claim:
An information handling system, comprising: data processing logic configured to process a first data stream of video data for a video display and a second data stream of non-video control data for a plurality of source devices, wherein said plurality of source devices are configured to transfer said video data to said video display; a data transfer interface comprising a plurality of data channels, said data transfer interface operably coupled to said video display and said plurality of source devices, wherein said data transfer interface comprises a Video Electronics Standards Association (VESA) DisplayPort interface and said plurality of data channels comprises a VESA DisplayPort main link and a VESA DisplayPort auxiliary channel; and control logic configured to use a first subset of said plurality of data channels to transfer said first data stream to said video display and to use a second subset of said plurality of data channels to transfer said second data stream to said plurality of source devices; wherein said control logic is used to perform Extended Display Identification Data (EDID) read operations on said video display to retrieve its EDID information upon activation of an individual source device of the plurality of source devices, and wherein said EDID information is used by said individual source device to perform DisplayPort Configuration (DPCD) read operations to train said VESA DisplayPort main link for the conveyance of said video data and said non-video control data between said video display and said individual source device; wherein said auxiliary channel is configured to transfer said second data stream of non-video control data in accordance with VESA monitor command control set (MCCS) parameters; and MCCS operations are performed once said VESA DisplayPort main link has been trained, wherein said performance of MCCS operations activates said video display and selects said individual source device for operation without the performance of an initiating action or an intervention action by a user.
