Maybe it can't determine the screen size correctly, and the right side is overscanned beyond what the display can handle.

What Mac model is this? If it's a desktop model, make sure your video monitor isn't the problem. Make sure your video cable works and is correctly plugged in, too.

Try running the Displays pane of System Preferences, and choose a display size with smaller size (lower resolution) than you normally use.
