I have a situation I have not encountered before. One of my users accidentally dropped a folder on the keyboard. Now the display shows horizontally rather than vertically (i.e., you have to turn the monitor onto its right side in order to view it normally).

I have checked the display settings, but I don't see anything that seems to affect this. I have rebooted the computer, still no luck. This is a Dell Optiplex 170L running Windows XP Professional. While I guess I may be able to correct this by using system restore, I have not tried that yet as I would rather understand how this happened.

When the computer is booting, the screen shows properly, and the Windows XP splash screen shows normally as well. As soon as the login screen shows up, however, it is back to this sideways display mode. This would probably be an interesting way to use your screen if you were working on magazine pages.

Thanks for any suggestions.
