Thanks Warp2search for the heads up on this post. ClearTweak Freeware allows you to change the contrast setting of the ClearType setting for Windows XP. ClearTweak is freeware and does not contain any spyware, adware, or any other type of embedded monitoring software. ClearType 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
Alternatively you can also use the online Cleartype fine tuner from Microsoft if you don"t want to install the program, the link to that can be found here at Microsoft
