  1. Right-click on your desktop, and then select Display properties or Display settings. Then, scroll down to Multiple displays, and select your desired option in the drop-down list.
    Extend these displays: This lets you use both monitors and have something different on each one. One of your monitors will need to be marked as your "main" display and will be the default monitor for most Windows functions. Just select the monitor and click the checkbox to mark it as the main one.
    Duplicate these displays: When using this setting, everything that is shown on one monitor will appear on the other. If the monitors have different resolutions, then all monitors with a higher resolution will be lowered to match the resolution of the monitor with the lowest resolution.
    Show only on: Use this to leave multiple monitors connected at once but toggle the oneyou're currently using. The other monitors will stay powered on but only show black or not display a video signal at all. This can be used when connecting a laptop to a better monitor without using the laptop's built-in screen. In this case, make sure your laptop is not set to turn off when you close the lid, or it will turn off the external monitor.
  2. Scroll back to the top, and click Identify. Large numbers will appear momentarily on each monitor. Remember these numbers when making the next adjustments, or click Identify to see them again.
  3. If any of the screens are upside down or sideways, select the screen with the matching number, and then scroll down and select the matching Display orientation.
    Landscape: Use when the original bottom of the monitor is also the bottom of the displayed screen. Use Landscape when the original bottom of the monitor is at the top of the displayed screen.
    Portrait: Use when the original bottom of the monitor is on the left side of the displayed screen. Use Portrait when the original bottom of the monitor is at the right of the displayed screen.
  4. Next, select the resolution of each monitor by selecting the monitor, and then adjusting the Display Resolution. Use the Recommended settings when your drivers and Windows are up-to-date.
