Abstract
An apparatus for video signal switching for use with an external graphics processing unit device includes an input unit of an information processing device configured to input a first video signal from an external device comprising a graphics processing unit ('GPU') and an input/output interface, a processing unit of the information processing device configured to output a second video signal, and a switching unit configured to determine a route for a video display signal that is output to a display unit, the route selected from an external route along which the first video signal is output to the display unit without going through the processing unit and an internal route along which the second video signal is output to the display unit. A computer program product and a system perform the functions of the apparatus.
