How to Run Two Monitors in Vista

Windows Vista automatically detects any additional monitors that you add to your system. Multiple monitors enable you to design or communicate with customers on one screen, while using the other for programs necessary to run your business. Alternatively, you can use this setup to display what you see on your monitor on a large screen or projector, enabling customers or employees to share your experience, learn how to use new software or view the capabilities of your program.

  1. 1.

    Connect your monitors to the available ports on your computer. For example, you might have two monitors, each using the HDMI interface, or one HDMI-compatible monitor and one VGA-compatible monitor. This method works best when your computer also uses a video card that enables you to connect multiple displays.

  2. 2.

    Turn on both monitors. Your Vista computer should detect the second monitor. Restart your computer, if it does not.

  3. 3.

    Open the Control Panel from the Start menu to edit dual monitor settings. Select "Personalization" from the "Appearance and Personalization" screen. Click "Display Settings" to view the settings for your monitors.

  4. 4.

    Click "Detect" if Vista does not detect your second monitor. Once detected, you will be able to choose how Windows handles your monitors. For example, mirroring shows the same desktop on both displays, while extended displays different content on each monitor.

  5. 5.

    Use the drop-down menu to choose resolutions and orientation for your monitors. Click "Apply" to confirm any changes.
