Lost output to external monitor
 

I'm using a decklink SP card to connect to a BetaSP deck. I run a studio tv monitor from the deck so I can preview my timeline on it while I'm editing. For some reason today the video output has stopped in FCP. Usually, when I'm not using FCP the external tv displays the desktop background and when I open FCP it turns black and then displays the canvas. Now it just stays on the desktop background and doesn't display anything. What happened?! Yesterday I used the deck to make a beta master dub and it seems that is when the problems started. It sounds like a settings/preferences thing to me, but I've tried every setting that I can think of and still no luck. Could it be a setting I fooled around with on the deck itself? Any help would be GREATLY appreciated!

You probably have already tried this, but:

View > External Video > All Frames

Sometimes I have to do this when starting Final Cut. Seems like it should work, given that your hardware is set up. (Although I go Firewire out to deck, so maybe it's an issue with your decklink??

Brilliant!!! Never had to bother with that setting before. Thank you!
