I have added the projector and I can map each projector but i still only get one output at a time. I select the output under syphon and i get what i select but i do not know how to select more than one output.
I did assign a projector to each output under the projector icon.

I am using an iMac with 2 thunderbolts ports that are connected to two triplehead2go's. One triple head is connected to three projectors and blended to create a triplewide screen set up in the middle of the stage and the other triplehead2go is connected to two projectors that project on angled walls...
