Abstract:
1. An electronic-device, comprising: a graphics processing unit having a head with links configured to communicate video signals, audio signals, data signals and a configuration signal corresponding to a physical connection to a currently selected display port in a pair of display ports; a multiplexer electrically coupled to the graphics processing unit, control logic and the pair of display ports, configured to selectively couple the links in the head to the currently selected display port based on a selection control signal that specifies the currently selected display port, wherein the selectively coupling of the links in the head to the currently selected display port is compatible with different operating systems that can execute on the electronic device; the pair of display ports, electrically coupled to the multiplexer and the control logic, configured to couple to displays and to communicate the video, the audio and a pair of configuration signals corresponding to physical connections to the pair of display ports, wherein the pair of configuration signals includes the configuration signal; and the control logic, electrically coupled to the pair of display ports and the multiplexer, configured to monitor the pair of configuration signals and to provide the selection control signal to the multiplexer based on the monitored pair of configuration signals, a policy setting and a default display port.
