I'd suggest powering up the AAO without the plasma connected first, once booted and in Windows, power-on and connect the plasma. Then try the Fn key to swap your display. This will allow Windows to install any drivers if need be and possibly detect the appropriate resolution to display on your TV.

 

Some software will not work if the TV is hooked up before the software is started. Example Corel DVD/BR player will appear to work but will run erratically if it is started when the TV is hooked up. However! If you get the movie playing on the computer and then switch to the TV it works.
