How to Change the Display DPI Scale in Vista
This will show you how to change the DPI (Dots per Inch) Scale to allow all items on your display screen to be smaller or larger.
If you set the DPI higher than 96, and you are running Windows Aero, the text and other items on the screen might appear blurry in some programs that are not designed for high–DPI display in Vista. If this is a problem you are having, you can help avoid this issue by using Windows XP–style DPI scaling. (See step 4C below)
Do not set the DPI to high or everything will extend way past the display screen, making them distorted and unreadable. If this happens, then boot into Safe Mode
and change the DPI scaling to a smaller number.
