In the classrooms that have a dual monitor setup at the teacher station, the left (Wacom Tablet) screen is set to MAIN PC by default and the right screen is set to EXTENDED PC by default. The right screen and confidence monitor in the ceiling are mirroring the same image. 

  • To change sources on the right display, press the Confidence Monitor Display Select on the Extron Controller. Select preferred source to be displayed. Do not reconfigure the PC display settings.

This is what the setup should look like once you have started up the system or after doing a system reset by tapping System Off > System Reset. Both PROJECTOR (RIGHT) and  PROJECTOR (LEFT) will be set to MAIN PC as well.
