I just purchased an Inspiron 1545 for my wife, who will be using it mostly in the same location at home.  Since I happen to have a Dell 1703FP monitor that I wasn't using, I plugged it in to see if I could rig it as a vertically-oriented screen for full-page use in Word.  However, when I plugged it in, it came on for about 2 seconds, then went black.  I tried to get the video card to make it the primary monitor, and it did the same thing.  It works fine with my desktop.  What is wrong, and can it be rectified?
