While it may not present itself as a problem on an average laptop screen, the wallpaper has to work on super wide screens where it's cropped to fit and is presented at 1:1 or even scaled up in some cases. Many otherwise suitable background images just fall short when observed at the nominal pixel view. Chromatic aberation and noise is also something that becomes apparent as you approach 1:1.  +##### Color Banding + +Images should look decent even on lower quality displays. Techniques such as dithering should be used for elements with low contrast areas that would otherwise be prone for color banding. ## License -CCBYSA / Public Domain / CC0 is preferred.
