Check your viewing angle
Make sure that the monitor is not tilted too far up, down, or to either side from where you usually view the monitor. The best viewing angle for the monitor is to view it at a 90 degree angle.
Check your current theme settings
Some themes can cause fonts to look blurry. For example, if you use a high-contrast theme, some fonts can be difficult to see because the background colors resemble the font color.

To change your current theme settings, follow these steps:
  1. From the Start Screen, type Change the theme, and then tap or click Settings.
  2. Tap or click Change the theme from the search results.


  3. Tap or click the theme that you want to change to apply it to your desktop.
  4. Do one or more of the following:
    • To change the background, tap or click Desktop Background, select the check box for the image that you want to use, and then tap or click Save changes.
    • To change the color of window borders, tap or click Color, click the color that you want to use, adjust the intensity, and then tap or click Save changes.
    • To change the sounds for the theme, tap or click Sounds, change sounds in the Program Events list, and then tap or click OK.
    • To add or change a screen saver, tap or click Screen Saver, click an item in the Screen saver list, change any settings that you want to change, and then tap or click OK.



Check your font size
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.


  3. Tap or click Smaller - 100% (default), and then click Apply.

  4. Log off your account, log on again, and then open Internet Explorer to see if the font looks clearer.
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.


  3. From the Screen Resolution window, tap or click the drop-down list next to Resolution.


  4. Move the slider to the resolution that you want, and then tap or click Apply.

  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.
