Try this:

Open Quicktime preferences (I use 7.0.1) and under “general” check the box “use high quality video setting when available” then look under the “full screen tab” and you will see your video monitor arrangement, select the little one that is your Decklink desktop viewr/TV monitor. Quit prefs and open a quicktime movie. If you now select to play “full screen” under the view options the movie will automatically start to play in the TV at full rez & speed. Pretty cool! There may be other ways but this works for me.

Good luck,

Jon Watkins
