All Notebooks with Windows XP and a TFT panel.
This issue may have to do with Windows XP, ClearType being enabled. ClearType improves font display quality over traditional font smoothing or anti-aliasing. ClearType improves readability on color LCD displays with a digital interface, such as those in laptops and high-quality flat panel displays. Readability on CRT screens can also be improved. Enabling ClearType is subjective from one user to another.
To disable ClearType un-check this option:
* Right Click the Windows XP desktop and select Properties
* Click the Appearance Tab
* Click the Effects Button
* Uncheck the box to "Use the following method to smooth edges of screen fonts"
