Setting Up Your Video Projector For Videos and Still Images
To display videos and still images on a video projector, the video projector must be configured in Windows as an extension of the Windows desktop, eg as Screen 2. SCS 11 supports up to 8 additional screens, and any such screen you use must be configured as an extension of the Windows desktop.
When SCS opens a cue file, if there is at least one video/image cue and the required secondary screen (eg video projector) is detected, then a maximized black borderless window is opened on the secondary screen, and any videos and images are displayed in that window. So the secondary screen remains black when not playing cues.
