As for the formats that do at least show up as not being invalid, the screen doesn't fit all the way on the LCD. For example when switching to one of the resolutions that work without giving invalid format (1280x1024)the bottom left part of the screen doesn't fit into my LCD. If I do move the mouse to that region the screen will shift over almost as if my screen is a web page that you can scroll from top to bottom and left to right.
All I would like to do is increase the resolution on my LCD even if that means giving up a secondary monitor (If that even has anything to do with it.) Help would be appreciated.
