The video card, and driver will have that setting. The video card driver icon in the system tray ( Lower right side of the screen, if there) can be clicked on, and there is a settings for rotation. But, as the other poster suggested, the video card may not have that option. Try the newer ati driver to see if it does. If not, get another video card, and download a good newer driver. Video card you have now is somewhat lacking and old.
Just found this site that provides a list of video cards that do have a rotate function, and the ATI 128 is listed, but not the Ultra. Don't know if that makes a difference or not. So download a newer driver and after it is installed, click on the icon in the system tray and find the rotation function

Did you try Ctrl+Alt+Arrow Key (in the direction you want to rotate it)?
I must have been half asleep when I posted that. I believe that key combination only works with an attached notebook LCD and not every one of them either.
There should either be a menu setup button on the monitor itself where you can get to such things or in the advanced settings area of the video card properties. I know some of this has been suggested already.
