PROBLEM TO BE SOLVED: To solve the problem that the connection detection is impossible about the connection of PC inputs because of no connection detecting pins, etc. prepared for D-sub connectors while some TVs detect the connection to external apparatus connection terminals, using pin-jacks with connection detecting pins, etc. SOLUTION: A connection detecting contact switch is provided for the D-sub connector to connect it to a circuit. The connection to the D-sub connector is detected to do processes of showing this on a screen, based on the information, automatically switching over the inputs, limiting the input switching over, etc. COPYRIGHT: (C)2006,JPO&NCIPI
