The fine print says it should work. Real life might be different. Do you have a genius bar, found at Apple stores, anywhere close? If so, make an appointment and let them make the connection for you. The genius bar is a free service and I've never found anything that they haven't been able to fix...and fix it quickly...if it's fixable.
Sounds like either the Monitor is bad or the Video Card is bad. Try plugging another monitor on the computer and if it can't show a display then more than likely the Video Card is bad. If it shows on the monitor you just plugged in, then the original monitor is bad.
You need to check your power options settings and modify it , so that your monitor does not turn off automatically.
If you are using windows xp , go in control panel and then there would be an icon for power options , double click the power options and then you would find settings which read turn off monitor , turn off hard disk etc... select the turn off monitor to never mode or as per your convenience and you would have your problem solved.
Dell monitors automatically go into power-save mode after a preset
amount of time when the computer is inactive. The Dell monitor will go
completely black, instead of showing a screensaver. This doesn't mean
that your Dell computer
has shut down. Instead, this allows your monitor to essentially turn
off until it's needed again. You can change how long it is before the
Dell monitor goes into power-save mode by changing your display
any key on your keyboard or move your mouse. Either will turn off
power-save mode. Alternately, you can press the power button on your
Dell computer tower or laptop.

mode. Stand-by mode allows the screensaver to appear.

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.
This problem may occur due to wrong driver of display card or wrong display settings.
Solution: 1- Start you computer in safe mode. 2- Remove display card driver. 3- Restart you computer. 4- Install display card driver (if it does not pick automatically).
Now it should show default settings. I hope it would solve your problem.
