Two PC monitors - Can't get one to work
 

I normally use two PC monitors with P-Pro CS3. Monitor #1 is used for P-Pro CS3 and Monitor #2 is used for playback of the timeline only. Recentely monitor #2 will not play back the timeline video. I know the monitor is working because I can share my desktop + mouse over to #2. When I go to Projects>Project Settings>General and click on playback options I get a Cineform window with options. I've checked off what I feel is appropriate. Still not playback in #2 of the timeline. Any ideas?

Thanks

I'm still having this problem. Before I loaded Cineform I could just select the two monitor option. Now I can't even get to that option menu.

Any ideas?

If you're using an nVidia card with the newer drivers, that may be the reason.
