Desktop backgrounds can have many different preferences. For instance a smaller image may be tiled where it is simply applied side by side across the computer monitor taking up the entire background of the desktop. Then another option is to use smaller images which may be centered while leaving a certain color or design on the outside of the image. One of the most popular settings is to set the background picture to take up the entire desktop background. However, many make the mistake of using a background image that is too small. So it is important to use an image that is high enough resolution to cover the resolution of your computer monitor.
