Abstract
A method and apparatus which provides bi-directional communication between a video monitor and a computer system unit. This enables the video monitor to inform the system unit of its capabilities without user involvement and also enables the system unit to directly control or adjust all the functions of the video monitor. In the preferred embodiment, a monitor/mouse interface provides bi-directional communication between the video monitor and the system unit. The monitor/mouse interface connects to the mouse and video connectors or the back of the system unit and in turn connects to the mouse and video monitor. The interface includes separate data paths from the system unit to the mouse and video monitor, respectively. Monitor control software is included in the system unit which can be used to control or adjust the output of the video monitor. When a user desires to adjust the output of the video monitor, the monitor control software directs the monitor/mouse interface to provide a communication path between the system unit and the video monitor, and the system unit relates the control information input from the user to the video monitor, which adjusts its visual output accordingl…
