How to redirect video output to external display?

How to display Tcpmp (or coreplayer or wmplayer) video (when flip is closed) on external display?

How to display album art (images) associated to an mp3 (when the flip is closed) on external display?

I'd like for other programs a behavior similar to camera behavior.

Excuse me for my English and thank you for your answers!
