Just beginning of starting windows It works only if VGA connector is disconnected before I start the monitor, wait for a click and sound of degaussing and then I connect it. If monitor is connected when I am turning the power on the it just keeps clicking It also does the following, when the system is running (computer is on, monitor is connected and running fine), if I disconnect and connect back the connector then display goes blank and it keeps clicking. On the other hand, when the system is running, if I disconnect the monitor (display is working), shut off the monitor, turn it back on, wait to hear the sound of click and degaussing and after that connect it back on, then it works fine.
