[Geometry correction won't change display]

I have two Displays coming from one pc and one of my displays will not respond to geometry correction.  It is stacked under the other display (for intensity and back up) on a different tier and when I change the geometry in the display window it changes, but nothing changes from the projector on stage.  hmmm

[simple Barco IP control]

On this same topic, does anyone know the control sting for change of input?  I have Barco CLM-10+ that I have had very good success with shutter open and close control strings and I would like to change inputs via Watchout.  I was looking at the control strings above for setting PIP and my head exploded.  thanks
