When setting the desktop background, you can select one image for each of your monitors. You can even choose a different image for each monitor by using a drop-down menu. The Desktop Background window allows you to change your background image, so you can change it whenever you want. To do this, click on the Start button, go to Control Panel, and then click on the Display tab. Then, select the Picture option and choose the position of your wallpaper. If you want to display different images on each of your monitors, you should first select the Span or Fill option.
