Changing digital tv screen size to work as pc monitor

Hello,
We've just bought an Acer Revo RL100 to hook up to our Sharp DTV. First snag is the main icons, tool bars, are all outside the view on the screen and cannot be seen. Clearly, the actual pixel surface extends behind the plastic facia of the TV. Does anyone have any solutions, please?

Have you tried changed the screen resolution on either the Screen Resolution (Right click desktop>Screen Resolution)?
Also, I know on my computer, I had the opposite problem, there was a black border around the screen.
I fixed it by going into the Graphics Cards Suite (Mine was ATI Catalyst) and look around in there.

Hope i helped
