?: nothing present right now
-: never saw such displays, so no wallpapers available. maybe use _really_ big images with the same aspect ratio
*1: small displays exclude high resolution
*2: 5:4 means 1280x1024 (the only available resolution for displays with that aspect ratio). thats not high resolution.
*3: Leaves a small stripe on top and bottom.
