A 4k wallpaper or background (also known as a desktop 4k wallpaper, desktop background, desktop picture or desktop image on computers) is a digital image (photo, drawing etc.) used as a decorative background of a graphical user interface on the screen of a computer, mobile communications device or other electronic device. On a computer it is usually for the desktop, while on a mobile phone it is usually the background for the ‘home’ or ‘idle’ screen. Though most devices come with a default picture, users can usually change it to custom files of their choosing A 4k wallpaper image may be centered, stretched, or tiled. When an image is centered, it is placed in the middle of the desktop and is surrounded by a solid color. When an image is stretched, it is stretched to cover all of the desktop. Only certain images can be stretched or they look distorted. An image that is tiled is placed on the desktop much like tiles are placed in a shower or a tiled floor. Tiling is commonly used for patterns instead of photos because a pattern is one square image that repeats itself across and down the screen, effectively forming a single image.
