A display apparatus (100) and a method for controlling the display apparatus are provided. If a display apparatus is in a power off state and an interface is connected to a cable, an output of a cable connection sensing signal is blocked.
The cable connection sensing signal may comprise a hot plug detect signal (HPD) or a display data channel signal (DDC_DATA, DDC_CLOCK). If a PC (10) connected to the other end of the cable does not receive the cable connection sensing signal, it determines that the display apparatus is disconnected from the cable.
