Dual monitor users can configure your dual-headed beast to display different wallpaper backgrounds on each monitor. Which can be completed with a third party software. Download Display Fusion to implement this.

Once the software is installed, you’ll notice a new tray icon. Clicking the Desktop Wallpaper item from the menu will open up the dialog where you can set the wallpaper for two monitors.

This application works good for both XP and Vista. For dual display wallpapers click here.
