  2. Tap or click Change the theme from the search results.

If your current font size or dots per inch (DPI) is set to larger than 100%, text and other items on the screen may appear blurry in programs that are not designed for high-DPI display. To fix this problem, set the font size to 100% to see whether the font looks clearer.

To check the font size, follow these steps:
  1. From the Start Screen, type Display, and then tap or click Settings.
  2. Tap or click Display from the results.

Digital cables vs. VGA cables

Manufacturers are now including both an analog connection and a DVI (Digital Visual Interface) connection on LCD monitors. When you connect your computer to an LCD monitor with an analog connection, the signal may become corrupted. When you use a DVI connection, there is no digital-to-analog conversion and corruption of the signal does not occur. The LCD monitor will give a much sharper image than on a CRT monitor when you use a DVI connection.

Screen resolution

Low screen resolution can affect font clarity. For example, with a resolution of 800 x 600 (where the monitor supports higher resolutions), fonts can appear blurry. If you change the setting to a higher resolution, it might help the fonts look clearer. It's a good idea to set your monitor to its native resolution — the resolution that a monitor was designed to display in based on its size. The resolution setting that has (recommended) after it is your LCD monitor's native resolution. This is usually the highest resolution your monitor can support. To see your monitor's native resolution, check the display settings in Control Panel.

To verify or change your screen resolution, follow these steps:
  1. From the Start Screen, type Change Display Settings, and then click Settings.
  2. Tap or click Change Display Settings from the search results.

  5. Tap or click Keep Changes to use the new resolution, or Revert to go back to the previous resolution.

    Note
    When you set your monitor to a screen resolution that it does not support, the screen will go black for several seconds while the monitor reverts back to the original resolution.

Upgrade your monitor

Some older monitors do not support higher screen resolutions. If you use a monitor that only supports resolutions of 800 x 600 or less, consider upgrading to a monitor that supports higher resolutions. There are advantages and disadvantages for LCD, LED and CRT monitors. CRT monitors are more affordable and offer better contrast ratios. CRT monitors can easily scale to various resolutions and provide a better color range. LCD and LED monitors are on average 80% lighter, use less power and are available in a larger variety of sizes.

The ClearType Tuner helps improve font display resolution so that letters on the computer screen appear smooth, not jagged. You can tune fonts for your particular display hardware.

If you use Windows 7, you can adjust ClearType settings by using the ClearType Tuner in the Windows Control Panel, under Display. If you have Windows Vista, you can use the online tuner. The online tuner must be used with Internet Explorer because it depends on an ActiveX control.
