It is vry likely that you have the screen set to a resolution lower than 1024x768 (default size of the LCD on a T22) and have the screen streach feature on. laptop displays cannot dynamically resize like regular monitors can, so the only way to get full screen at under their intended resolution is to streach the screen. That will prouce a very bad-looking display. I suggest setting the display resolution to 1024x768, it will look much better.
