HD wallpapers are images for use as a background on a computer, but they are higher quality images suitable for modern resolutions on computer monitors. Low-resolution monitors have a lower pixel density, which can distort or diminish high-quality images when presenting them as backgrounds.
High-definition wallpapers have a greater pixel count than standard images, which allows HD images to be enlarged to fit larger monitors. HD wallpapers offer vivid colors and better contrast than their standard-definition counterparts.
Background images enhance the viewing environment for computer users. Images come from a variety of sources, such as Internet sites, digital camera uploads or graphics created with computer software.
