There is no wireless display app for windows phone making Continuum inoperative. First without the app I cannot adjust image size on the tv screen. Also, there's no way to update the firmware on the device? Are there work arounds?
You use the continuum app for your miracast device.. just start it up and you will see the option wired or wireless there.
display scale can be change in the display settings once the screen is attached. and no.. there is no way for firmware update. they come OTA. The device is just a few days old ... dont expect any firmware updates anytime soon
