Well the monitor just won't display anything, seen this now on a few Dell's, the orange light stays on when you turn on the PC and the monitor thinks it's in standby mode. If I plug in a different monitor it works fine, if I plug something else into the original monitor, it displays fine. The two just don't seem to like each other. If it try pressing the monitor menu button, the message says to press the power button or any key on the keyboard, but this of course doesn't work, else I wouldn't be posting about it
Anyone got any ideas as to why they won't talk?
