Display apparatus and method

摘要

A display apparatus includes a communication device for executing a communication with a host computer via an interface cable. The display apparatus also includes a display having a display screen for displaying image data transferred in synchronism with display timing from the host computer via the interface cable, a connector connectable to the interface cable that communicates with the host computer, and a detector for detecting whether or not the connector is connected to the host computer via the interface cable. A connection/disconnection state of the interface cable is recognized on the basis of the detection result.
