When a switch S1detects that the cable6is connected to the connector C1, a switching circuit2is switched to the cable-side to display the image signal via the cable. When the switch S1detects disconnection of the cable6, the switch circuit is switched to the side of a CPU5to display the image signal via the wireless LAN.
