Abstract
The present disclosure relates to computer-implemented systems and methods for wireless display discovery. The method may include receiving, by a computer, a selection to detect wireless display devices. The computer may include one or more processors, a radio transceiver, and a microphone. The method may also include identifying, by the radio transceiver, a plurality of wireless display device and transmitting, by the radio transceiver, respective connection requests to the plurality of wireless display devices. Additionally, the method may include transmitting, by the radio transceiver to the wireless display devices, respective requests for inaudible audio signal transmission. The method may also include receiving, by the microphone, a plurality of inaudible audio signals from the wireless display devices. Further still, the method may include determining, based at least in part on the plurality of inaudible audio signals, whether any of the plurality of wireless display devices are in the same room as the computer.
