Abstract
Methods and apparatus are provided for efficiently controlling source computers connected to a display system. A control computer is connected to one or more source computers and video output is shown on a display system. A mouse and associated input devices may operate in video processor mode or source computer mode based on mouse x-coordinate and y-coordinate position information. Other modes such as control computer mode are also possible. In particular instances, a mouse and associated input devices operate in source computer mode to control a particular source computer when the mouse pointer position resides within one of the source computer windows. A mode of operation may switch based on a change in mouse position.
