Abstract
A monitor interface cable for transmitting display data and command data between a computer system and a display monitor preferably including a microcontroller. The monitor interface cable enables both display and command data to be transmitted simultaneously from the computer system to the display monitor. Inside the computer system, data containing the commands written to a particular memory location in a video buffer card is applied to various signal lines located in the monitor interface cable. These signal lines are coupled to the microcontroller located in the display monitor which receives the commands and performs various controlling functions in response. Status information in the form of a command is transmitted back across a second signal line to the computer system where various software programs including drivers receive and process the status information. Display data is simultaneously transmitted over other signal lines also located in the monitor interface cable.
