ClearType is a software technology that improves the readability of text on Liquid Crystal Displays (LCDs) and makes the words on your computer screen look almost as sharp and clear as those printed on a piece of paper. It can even improve your reading speed between 10 percent and 15 percent.
To turn it on, go to Microsoft’s ClearType Tuner webpage, click the box to “Turn on ClearType” and then click NEXT to start the install and configuration wizard.
