Screen Trigger

Low-voltage signal sent from a video projector to a motorized screen causing the screen to lower or roll up. Screen triggers are found primarily on more expensive projectors. They make viewing video using a screen and projector easier since the viewer does not need to manually raise and lower the screen (screens working with screen triggers contain motors to do this) nor does the viewer need to flip a switch to raise or lower the screen. The process is automatic making it convenient for viewers.
