Everyone has a different idea of good font smoothing. What is nice and smooth to you may be blurry to someone else. That is why Microsoft included the ClearType Text Tuner in Windows 7.
Start the ClearType Text Tuner by clicking on the Start Button and typing in cttune and then hit Enter.
Then just follow the wizard and select the options that look best to you on your LCD monitor.
Click Finish to save your changes.
