My PC and other things i have plugged in work perfectly fine to my knowledge. But the Monitor does not seem to be getting a signal, im like 99% sure i plugged the cables in correctly and the monitor is alive, it just doesnt get a signal. My PC also gives of a beep code which consists of 1 long and 3 short beeps following. Any solutions?
