I am trying to display my MacBook Air screen on a TV screen, using a Wireless Display Adaptor. The TV is not an Apple TV. Although the Display dialogue under System Preferences show the option to "Show mirroring options" there are no devices detected alongside "AirPlay Display".
I have tried the function "Detect Displays", but this makes no difference - the Mac is not able to detect devices.
Could this be because the Wireless Display Adaptor is a Microsoft device? The device documentation suggests Macs should be able to mirror ok.
