Abstract:
1. An information handling system comprising: a PCIe transceiver configured to transfer PCIe peripheral information for a peripheral; a video display subsystem configured to process video information for a display; a host DisplayPort connector coupled to the PCIe transceiver and the video display subsystem, the host DisplayPort connector configured to multiplex the PCIe peripheral information to two data lanes of the host DisplayPort connector having four data lanes and the video information to the other two data lanes of the host DisplayPort connector in response to the presence of a DisplayPort/PCIe multiplexer at the display, wherein the presence of the DisplayPort/PCIe multiplexer is detected by retrieving an identifier from the display; a display DisplayPort connector of the display coupled to the host DisplayPort connector to receive the PCIe peripheral information and the video information through the four data lanes, wherein the DisplayPort/PCIe multiplexer at the display is configured to demultiplex the video information from the display DisplayPort connector to represent at the display and the PCIe peripheral information from the display DisplayPort connector to communicate with the peripheral via a PCIe connector of the display, wherein the information handling system is configured to transfer the PCIe peripheral information to the host DisplayPort connector to communicate with the display DisplayPort connector of the display only if the DisplayPort/PCIe multiplexer at the display is present.
