Method and apparatus for controlling monitor using video signal

A method of controlling a monitor using a video signal, wherein a computer transmits the video signal and controls various parameters for adjusting the picture of the monitor and the monitor has a microcomputer, the method comprising the steps of:

• selecting a function to be controlled;
• converting a level of the video signal into a code value to indicate the selected function;
• receiving the video signal transmitted from the computer with the microcomputer in the monitor;
• and
• analyzing the video signal so as to determine and to control the selected function;
• said method further comprising the steps of storing software for controlling the monitor in the computer, and executing the software according to selection by a user;
• wherein the selecting step comprises selecting a monitor control function that the user wants using one of a keyboard and a mouse;
• and
• wherein the method further comprises transmitting R,G,B color signals corresponding to the control function so as to transmit the selected control function to the monitor.
