Typically, the higher the
dots per inch (DPI), the better the fonts will look. If you set the DPI higher than 96, and you are running a
Windows Aero theme, the text and other items on the screen might appear blurry in some programs that are not designed for high–DPI display in this version of Windows. You can avoid this issue by using legacy DPI scaling (
Windows XP style DPI scaling) for these programs.
