ClearTweak allows you to change the contrast setting of the ClearType setting for Windows XP.

The program is designed to enhance LCD displays. It may appear slightly blurry on standard desktop monitors.

To use ClearType, you must have a video adapter and monitor that support a color setting of at least 256 colors. Best results are achieved with High color (24-bit) or Highest color (32-bit) support.

If you have a Notebook computer, give this a try, it will significantly improve readability on your screen.
