I have this problem with my monitor. Everytime at the PC startup (later on it works fine) i have troubles turning on my monitor. When computer is starting up(or sometimes in windows) i click the power button on my SyncMaster 940bf. Light goes on but soon it goes off. Then it goes on but if i click it at 2nd cycle it wont be responsive. Also when the light is on i will hear a beep and monitor will become little more brighter for a second or less. Today i struggled with it for about 5mins but now its working fine without any problems.
