A display apparatus includes a communicator configured to be operable in one of a first state, which enables communications, and a second state, which disables the communications, to receive a beacon signal for connecting with an external apparatus; a display; and a controller configured to control the communicator to operate in the first state to receive the beacon signal for signal receiving sections corresponding to transmission times of the beacon signal and a second state for remaining sections, and in response to the communicator not receiving the beacon signal for the signal receiving sections in the first state, to control the communicator to adjust the signal receiving sections to receive the beacon signal. With this, if the beacon signals for connecting with the external apparatus are not normally received, the display apparatus may adjust the signal receiving sections to maintain the connection with the external apparatus.
