ClearType Tuner is a pretty cool feature that I came to know about through an article on detector pro. It is generally really helpful and a blessing in disguise to people like me who have eyesight problems. It makes the text appear relatively clearer and thus reduces the strain on the eyes. The text appears smoother and darker. Infact you can sharpen it to the extent you want. If for reasons you want the text to appear blurred, you can do so. Reading lengthy pieces of material becomes easy with this technology. In short, it tunes up your display pretty well.
