Look at your desktop right now. It’s so colorless and dull and somewhat boring. It’s time you spruced the place up a bit. And it just so happens here we have a collection of high-res 4K PC game art for that very purpose. Each of these 4K (3840×2160) desktop wallpapers are set to a desktop-friendly 16:9 aspect ratio, and they’re all lossless PNGs as well because compression is not good.
