How can I span wallpapers over two monitors in Mac OS X?

Question

Is there any way to get a single wide desktop wallpaper to span a dual monitor setup in OS X?

Answer 1

Without splitting the image by hand into two halves (one for each monitor)? Not currently.

Answer 2

Their is a program called Multiscape that would automatically do what Chealion explained by getting your screen dimensions and automatically sizing and splitting the wallpaper. Although the google code page is down. If you want to go on a treasure hunt Multiscape is what you're after.

Answer 3

The Mac App Store app Multi Monitor Wallpaper worked perfectly for me, despite my rather unusual display configuration:

• MacBook Pro (2017, 15")
• Four external monitors (5 total monitors)
• Combination of retina (built-in screen) and non-retina (all 4 externals) displays
• 4 of the monitors are side-by-side, while the 5th is positioned on top of (above) the others
• One of the external monitors is in portrait orientation (other 4 in standard landscape orientation)

Multi Monitor Wallpaper shows you an outline of your combined monitor layout, and allows you to stretch / zoom / reposition your selected image across the monitors.

It then automatically handles cutting up the image and setting it as the background image for each monitor.

I have no affiliation with the app; I'm just a fan!

the google link is down. I found the binary and compiled it. I tried to find a way to contact the creator, but to no avail. I apologize in advance to you, mystery person. http://rapidshare.com/files/330982889/MultiScape.zip
