I purchased a Dell Red Had addition computer. I hooked up my monitor to the computer and turn the computer on. My monitor just shows me "Analog Self Test" and shows bars of Red, Green etc. I tried "autodetect" and got the same result. I have the correct connection cable. It is DVI-D, but I still am not getting signal from the computer to the monitor. Dell sent me three discs.
1) Installation disc (I'm assuming they already installed Red Hat)
2) Source
3) Supplementary disc

I do not know where to go from here. Can someone please help me or direct me to a location that can help me?

Thanks, Steve
