A computer microcomputer(12) receives the onscreen display signal output from the monitor microcomputer through the communication tool(13) and makes the onscreen display signal multiplexed to a signal output from the video card(11) of the computer. The communication tool between the monitor(200) and the computer is a DDC(Data Display Channel).
