Configuring Different Wallpapers in Windows 10

Open the Start menu. Just click the Start button in the bottom-left corner of the desktop screen.
Select Settings. This has a gear-shaped icon and can be accessed from the left side of the Start menu when you open it.
Select System in the Settings menu.
Click on the Display tab. This shows you the menu for configuring your PC's display, including multiple monitors.
Configure your monitors' display. Once you have the Display menu open, you can set your monitors as display 1 or display 2 and set them to the appropriate resolution(s).
1. Remember the number of the display whose wallpaper you want to change.
Navigate back to the Settings menu and select Personalisation. This opens up a menu of settings you can configure to customize your PC.
Click the Background tab. This pulls up the wallpaper customization menu for Windows 10.
Right-click on one of the wallpapers you want to set. Ordinarily, clicking on an image in the Background menu will automatically set it as the wallpaper for both monitors. Right-clicking on an image pulls up a list of more options
Select Set for monitor 1 or Set for monitor 2. This will set the image as the wallpaper for one monitor, allowing you to select a different image as the other monitor's wallpaper. If you have more than 2 monitors, you'll see options for them here as well.
Set your wallpapers. Once you've found the images you want to use for your wallpapers, make sure to right-click and select them for the monitor you have in mind. Once you're done, your new configuration will be all set.

Configuring Different Wallpapers Manually in Windows 7

Configure your monitor display settings. You'll need this set up to figure out how to configure your wallpapers.
1. Right-click on any blank space on the screen and
2. Select Screen resolution in the menu that pops up. A new window will then pop up with the display settings menu.
3. When you're done configuring your display, click Apply.
Search for images you want to use for wallpapers. Open Google Images, or any other image browsing site, and select at least 2 images to save for using as wallpaper images.
1. When selecting images, make sure to go with ones that are the same resolution(s) as your monitors.
Open an image editor. In order to get the images into a format that'll display across monitors, you'll need to format them into a custom image (Windows 7 doesn't have features for wallpapers on multiple displays that are available in Windows 8 and 10).
Create a new blank image. This menu should have a window with fields for setting the dimensions of the image.
Input the dimensions of your monitors. To ensure the image is formatted correctly, you'll need to input the combined width of your monitors as the image's width and the height of your tallest monitor as the image's height.
Insert your wallpaper images. Once you have the new blank image set up, open the images you saved and arrange them in the way you'd like them displayed.
Save your custom image. Once you have your wallpaper images arranged to your liking, save the new image as a JPEG or PNG file in a folder for easy access.
Open the wallpaper menu. You can do this by right-clicking a blank space on the screen and selecting Personalize from the menu that pops up, then selecting Desktop Background in the Personalization menu.
Click Browse…. This pulls up a dialog box where you can navigate to the custom image you saved.
Select your custom wallpaper image. Once you've navigated to it, click Open to preview it as your wallpaper.
Set the picture position to Tile. Since you'll be displaying this image across dual monitors, the Tile option works best for displaying the image in this manner.
