Force idle Projection display to black screen: When selected, the monitor selected for Projection will be made blank whenever Worship LIVE! is running and in the foreground. This helps to reduce the chances that a stray window or mouse cursor will cause visual distractions. This feature is not perfect, since it does not completely turn off the video card, and if you minimize the program or bring another application to the foreground, those windows could appear on that monitor. This feature does nothing if only one monitor is enabled.
