Unlike LCD montiors, CRT monitors can accept a wide variety of resolution settings.

Blurry text on a CRT monitor is the result of the computer's screen resolution settings. When the resolution is set too low, the text appears fuzzy or "blocky," depending on your video card. At higher resolutions, the text appears sharper, but it is also smaller on the screen. Windows Vista will automatically choose a default resolution based on your hardware, but you can customize the settings to your individual preference. LCD monitors have a specific recommended resolution, but CRT monitors are more flexible with the resolutions they will accept.

Instructions

    • 1

      Check the specifications for your monitor. The manual will list the available resolutions.

    • 2

      Click the "Start" button on the Windows Vista task bar and select "Control Panel."

    • 3

      Choose "Appearance and Personalization" and select "Personalization."

    • 4

      Click "Display Settings" and move the slider to the appropriate resolution for your monitor. If colors on the monitor appear off, change the color setting to "Highest (32 bit)."

    • 5

      Click "Apply" to save the changes. The monitor will switch to the new resolution. Click "Accept" to accept the changes.

Tips & Warnings

  • If you don't have the specifications handy, you can go by monitor size. For monitors 15 inches or below, start with a resolution of 1024 by 768 pixels. For monitors 17 to 19 inches, use a resolution of 1280 by 1024 pixels. For monitors over 20 inches, use a resolution of 1600 by 1200 pixels.

  • If the monitor goes black after you click "Accept," it means you have set a resolution the monitor does not support. This typically happens when you set a resolution that is too high. Simply wait a few seconds, and Vista will revert to the old settings.
