Op you're retarded, just use any dual screen wallpaper and deal with the fact that it won't show the entire picture on the smaller monitor, but cut off it's top/bottom/however you set it up.
the inches don't matter, I'm using the same setup but I barely use a dual screen wallpaper,
I'll post something I made myself from a few wallpapers that fit your specifications,
seriously just learn the basics of photoshop and make your own dual screen wallpapers.
