Set one background to stretch across multi-monitor display?

I have two monitors and my coworker has three. We were wondering if there was a way to set a single background image to stretch across all the monitors.

Right now it's the same image but repeated, so it looks like the same image three times in a row. I would like it to be so that the three images/screens combine to show one image if that makes sense.

If I can't set one image to stretch across the screens like that, is there a way to set a different background for each screen?

Edit: I just wanted to clarify: I am not talking about one image stretching from his monitors to mine, just stretching across our own monitors.

Solution 1:

Set your wallpaper to Tile. If the background is sufficiently large enough, it will stretch across the monitors. If it isn't, it will start repeating at the ends. You can use an image editing program to adjust the resolution or add whitespace to get it to work perfectly.

You can also use this trick to get different wallpapers on each monitor.

Solution 2:

Display Fusion should do the trick.

There are two versions, a free and a pro version. What you are looking to do only needs the free version.

Solution 3:

Bit late I know, but for future people with this need; Pr09het's Website - MultiBackground is easy to use and freeware!

Solution 4:

I use 2 programs called "Multiwall" - http://windowbox.me/multiwall/ and "Dual monitor task

bar" for extended task bars across all three monitors - http://sourceforge.net/projects/dualmonitortb/?source=recommended.
