ABSTRACT:
In the computer 1, the control information for screen display incorporated in the keyboard and software is processed by CPU2 and sent to the display device 6 via the communication controller 5. The microcomputer 7 in the display device 6 fetches the control information from the communication controller 8 and controls a predetermined part of the video circuit 11 or deflection circuit 10. In this case, identification information is sent to the display device 6 from the computer 1 first and when it matches with the identification information stored in the memory 9, the above control is permitted.
