Enjoy different wallpapers on your dual monitor set-up. (desktop image by Madera from

Most laptop and desktop computers come with support for dual monitors. Setting up the second monitor as an extended monitor is a painless process.

You can change the background on the second monitor and enjoy that wallpaper in full resolution while leaving your main monitor's background intact.

  1. 1

    Download and install DisplayFusion. When installing, use the default settings and installation directories. When you are finished, DisplayFusion will be present in your system's task bar.

  2. 2

    Connect or power on your second monitor and ensure it is receiving a signal from your computer. If the monitor is not recognised by your computer, it will not be recognised by DisplayFusion.

  3. 3

    Right-click on the system tray icon and select "Desktop Wallpaper" from the resulting menu.

  4. 4

    Click "I want to use a different background on each monitor" under Background mode.

  5. 5

    Click the picture that represents your main desktop. It will be labelled with "1P." Click the "Load from" button and select "My Computer." Navigate to the image that you want to use for the main desktop's wallpaper. Under the "Size Mode" drop-down menu, you can select how the program will deal with different aspect ratios.

  6. 6

    Click on the picture that represents your extended desktop and repeat the steps listed from Step 5. You can select a different wallpaper for this monitor. When you are finished, click "Apply" followed by "OK." Your computer will take a moment to refresh with your new settings and wallpaper in place.
