Each of these 4K wallpapers (that's 3840x2160, pixel fans) has been set to a desktop-friendly 16:9 aspect ratio, and with minimal compression so they look super sharp on your monitor.

To prepare for Build 2021, you can grab some 4K wallpapers shared on GitHub. There are also social stickers, wallpapers for Microsoft Teams, and watch faces on GitHub for Build 2021.

If so, change it up! Use Microsoft’s Bing Wallpaper app to refresh your PC’s desktop wallpaper with a new, gorgeous wildlife or landscape photo every single day. Sound familiar?
