Selectively transmitting signals

A method comprising:

• communicating signals of at least one data lane of a serial bus through a data lane interface;
• receiving a video display signal from a video card through a video interface port;
• and
• transmitting the signals of the at least one data lane and the video display signal to a high-speed signal combiner in response to determining that the high-speed signal combiner is processing the signals of the at least one data lane and the video display signal for output as a combined video display signal, else transmitting the video display signal to a video output port in response to determining that the high-speed signal combiner is not processing the signals of the at least one data lane and the video display signal for output as the combined video display signal.

A system comprising:

• a motherboard;
• a high-speed signal combiner;
• a data lane interface that communicates signals of at least one data lane of a serial bus of the motherboard;
• a video interface port that receives a video display signal from a video card;
• and
• a traffic circuit that transmits the signals of the at least one data lane and the video display signal to the high-speed signal combiner in response to determining that the high-speed signal combiner is processing the signals of the at least one data lane and the video display signal for output as a combined video display signal, else the traffic circuit transmits the video display signal to a video output port in response to determining that the high-speed signal combiner is not processing the signals of the at least one data lane and the video display signal for output as the combined video display signal.
