Monitor Troubleshooting

There aren't any electrical engineers that read this (that I know of), so this request will probably be useless.  Basic idea:  I've got a monitor.  As is, the picture is shifted up maybe an inch to an inch and a half from the bottom of the screen.  I can stretch it so that it moves down into there, but then the picture goes off the top of the screen.  The problem is that no matter what I do with the vertical position option, the picture does not move.  All the way to the top?  Nothing.  All the way to the bottom?  Also nothing.

I'm looking for any ideas on how to get this working properly (as it would be some extra cash if I could get it working.)  The monitor is a TVM AS6S, and every other option appears to work.  Anyone?
