Imma try to keep this as simple as possible....Cause in my head it seems very complex. Basically I need to project a portion of my computer screen A over a projector. Reason being is because the portion will be the screen of another computer (Computer B) and I will be controlling things live through Computer A and as expected I don't want the audience seeing the "behind the scenes" work. Your probably why I have this complicated set up....It's because Computer B will be a good few feet away from me and the webcam will be used, but I still need to control it so I need a way to do so without being in front of the webcam. I probably just lost most of you....I'll try to explain better if I need to.
