Color Setting Must Support ClearType

To use ClearType, you must have a video adapter and monitor that support a color setting of at least 256 colors. Best results are achieved with High color (24-bit) or Highest color (32-bit) support.
To change the color quality:

• Click Start > Control Panel > Appearance and Themes > Display.· On the Settings tab, in the Color quality list, click a different color setting.
