Abstract
The present invention provides a method and apparatus for optimizing the transmission of video configuration data in a system comprising a host computer and a display monitor. The invention comprises a wireless video source adapter connected to the host computer and a wireless video sink adapter connected to the monitor. Upon system startup, the video sink adapter acquires EDID information from the monitor and transmits it to the video source adapter, which does not activate its connection and indicate its presence to the host computer until after receiving the EDID information. The video source adapter then supplies the EDID information to the host computer in response to EDID requests from the computer. In this manner, the video source adapter acts as a virtual proxy for the display monitor from the point of the view of the host computer. The host computer then uses the EDID information to configure its video signal to match the parameters of the display monitor.
