If you have to stare something for 10 hours (in my case 12 hours) you better have something interesting. I am a great fan of good wallpapers and my favorite time pass is finding wallpapers.
Recently I joined new office, here we have dual monitor setup. This prompted me to hunt for dual screen wallpaper. Sure there are thousands of sites to find wallpaper on web, but not lot of them offer dual screen wallpaper. Here I present you over 20 resources to find excellent dual screen wallpapers.
