Wallpaper on dual screens

I've got two Dell 2209WA screens, one in landscape mode and the second one in portrait, in a dual-screen setup.

Can I set a different wallpaper on each screen as it looks a bit odd that the second monitor shows the same background but only in the middle portion of its screen?

What does everyone else do with their backgrounds when they have a multi-screen setup with a combination of landscape and portrait mode?

thanks

I use this to change the background and then exit.

Ultramon is good, buggy in some respects, but worth a shot.

If you want to avoid using extra software
simply joint/crop/scale your two wallpapers into the same file with the resolution of your two monitors, and use that as wallpaper. It will show across two screens.

Display Fusion sounds like what you need.
