Abstract: The present invention relates to a wireless display system that minimizes a case in which a control signal does not reach a control target due to interference or the like when a remote control device transmits the control signal to a receiving module or a transmitting module, and a method for operating the same. The wireless display system includes a receiving module including a display unit, and a transmitting module configured to transmit, to the receiving module, an image to be output by the display unit. The receiving module and the transmitting module share a control signal received from a remote control device.
