Abstract
In the computer, the control information for screen display incorporated in the keyboard and software is processed by CPU2 and sent to the display device via the communication controller. The microcomputer in the display device fetches the control information from the communication controller and controls a predetermined part of the video circuit or deflection circuit. In this case, identification information is sent to the display device from the computer first and when it matches with the identification information stored in the memory, the above control is permitted.
