Hey Gonk,
No, the new Key Digital swithcer that I would be using is actually NOT automatic. Has 2 buttons on the front and 4 inputs under each button. You can actually send 2 seperate signals, one to tv and one to projector at the same time. It is not an auto switcher like the other one, this is a 2 zone although I would only be running one source to one display at one time. Thanks.
