An image display apparatus which controls an external device transmitting data using a USB connector is provided. The image display apparatus includes a first connector and a second connector which receive an image signal, respectively, a display unit which selectively displays the image signal input via the first connector and the second connector, and if the image signal input via the first connector is displayed on the display unit, a central processing unit (CPU) which stops an external device connected via the second connector from transmitting an image signal. Accordingly, resources in the external device can be efficiently managed by stopping unnecessary operations.
