Abstract
An interactive monitor trouble-shooting device includes a micro-processor based control unit which detects the horizontal synchronization signal and the vertical synchronization signal from the video card of a computer. If no such signals are detected, the control unit displays a series of trouble-shooting steps to be followed by the monitor user for fixing the problem of receiving no such synchronization signals. The trouble-shooting steps may also be displayed in such a manner to test the color display function of the monitor, wherein the monitor screen is divided into at least three sections or areas, each having a background color of one of the three elementary colors. The control unit also allows the monitor to enter a power saving mode when such synchronization signals are cut off during normal operation of the monitor.
