At no point do we get any display of the desktop or mouse pointer on the tv. Typically after it displays "connecting to" it goes straight to a black screen after(with no errors on the tablet end). After multiple connections, we can occasionally see a very brief "HDCP authentication error" display on the tv. At that time, no applications are open except the WiDi manager on the tablet, so certainly aren't trying to play back any content of any sort.
