It is not as simple as it appears to be for Microsoft to let you do so with its desktop software. Finally, save the image and set it as your wallpaper.Īlthough Windows 10 includes multiple virtual desktops, it does not include wallpapers. Once you’ve found or created an image that is wide enough, open it in an image editing program and crop it to the desired dimensions. If you want your wallpaper to display across two monitors, you’ll need to select an image that is at least as wide as the combined resolution of both monitors.
