I did go thru the forum posts and found nothing on how to actually do this so you have a preview screen on your computer and an external screen for preview playback only.
In CS5.5 go to the "Program" window in the upper right hand corner there is a menu icon, select it and on the bottom there is a "Playback Settings..." item. Click on that and you will see in that window an option for "External Device" that has an default selection of "None" clicking on that you will see (if you have the second monitor active) an option for your second monitor for payback.
P.S. When you go to CS6 you will find this option now under "Edit", "Preferences"
Sweet setup. I was using a 32 inch tv wall mounted for vegas with Intensity and it worked great until vegas 11 and dslr footage.
So you can't get the full screen view directly in PP Harm? Say if I had 1 monitor and a 32inch tv for full screen like your top monitor?
Thanx Bill. I will look for this as well.
