Abstract
A method and an apparatus for automatically selecting an input device from a plurality of input devices coupled to an information handling system via a plurality of inputs, each corresponding to one of the plurality of inputs are disclosed. The plurality of inputs are scanned by a signal detector for the presence of a signal provided by one of the input devices to determine whether a signal is present on one of the inputs provided by the corresponding input device. When a signal is detected, the automatic video multiplexer selects the input on which a signal is detected according to a predefined hierarchy such that the information handling system receives the input signal provided by the corresponding input device. If a signal from a new input device is detected, the input corresponding to the new input device is selected, and the input device is configured to operate in conjunction with the information handling system.
