This dual-display system allows the user to present material from two different a/v sources at the same time. The touch panel is used to select which source goes to which display. There are basic settings along the top row and an advanced routing page to enable you to get more creative with your display. "PC display 1" is the Instructor Station PC's main desktop; "PC display 2" is an extension of that desktop. Sources sent to the second display will preview on the touch panel. This preview window can be enlarged by touching the display as indicated. A second touch restores the controls. Dual display rooms offer significant flexibility but they are somewhat complex. If you would like an orientation please call Instructional Media Services (83059).
