ABSTRACT:
A display apparatus connected with an external video source through a video cable having a first cable connector and a second connector connected to the external video source includes a display connector having a plurality of signal pins to which the first cable connector is connected, a connecting sensor connected at least two or more of the plurality of signal pins to output a first connecting sense signal to inform a connecting state between the first cable connector and the display connector, and a second connecting sense signal to inform the connecting state between the second cable connector and the external video source, and a controller to output information about the connecting state between the first cable connector and the second cable connector based on the first and the second connecting sense signals from the connecting sensor. Thus, the display apparatus can supply the information about a connecting state of a first cable connector and a second cable connector, respectively, in the display apparatus connected with the external video source by the video cable having the first cable connector and the second cable connector.
