I have a Dell XPS 18 and want to use an external monitor with it. The monitor has VGA and DVI-D inputs. The XPS 18 has no video output ports, but it does support Intel WiDi. I have a Netgear P2TV2000 WiDi receiver, but it only has composite and HDMI outputs. I'm connecting the receiver to the monitor with an HDMI cable and an HDMI/DVI-D adapter.

So, in short, the video path is:

Computer → WiDi → WiDi receiver → HDMI cable → HDMI/DVI-D adapter → Monitor

After setting all this up, I can't get anything to display on the monitor. At the moment I power the monitor on, I can see my desktop for a brief fraction of a second, and then everything goes black.

All of the relevant drivers have been updated to the latest versions. When I use a different WiDi-enabled computer to connect to the same monitor, everything works fine. When I use the original computer and receiver to connect to a TV, everything works fine. It's only when I connect the original computer to the monitor I want to use that the connection fails.

What could be going wrong here, and how can I get the video to work consistently?
