"Finally! I've found what I've been looking for! I've always had such a problem trying to set up a decent dual or triple screen panoramic wallpaper, I've spent countless hours in photoshop trying to break up the photo, this took me 3 seconds and I was done! Definitely recommend this to ANYBODY!! THANK YOU!!"

Works Perfectly…

Each new version of this app improves it’s already great features. The app works flawlessly even after reboot. I am a landscape photographer and have hundreds of panoramic images. Now I can easily use all of my landscapes as multiple monitor backgrounds. Without this application I was hand cutting each image for each screen. Now it’s as simple as selecting one of my panoramas, and then it’s instantly a dual screen background. This is a flawless app and it working great on my dual 4K monitors. Each of these monitors has a screen size of 3840 X 2160. I’m very impressed how easy this was!

* * * This app can be automated using AppleScript to quickly change your wallpaper. See my post at the developer’s support forum. Using an AppleScript is how I was able to accomplish this. #### Hopefully the developer can add this as a standard feature. This is a GREAT APP !

Useful, but doesn’t scale independently

I have a very high DPI MacBook Pro Retina, and a very low DPI 1080p monitor next to it. In the past I’ve gone to great lengths to get my multiscreen wallpaper to line up across both screens. This does half of the job - it let’s me grab 2 chunks of the image according to the resolutions of the monitors, but it doesn’t take into account the DPI, so the images have completely different scales and can only align at one point. I would like to able to calibrate the relative sizes of my monitors so it can scale the image for one of the screens to match the other. Maybe you could draw two lines between the screens, then give me position and scale controls to adjust until both of the lines connect. Maybe too much to ask for in a $3 app, but very useful with the increasing range of screen densities.

Hi wilcoxst,

As of version 2.10, you can now manually set the physical size for each monitor and Multi Monitor Wallpaper will adjust the image accordingly. Please give it a try and let me know what you think :)

Not a Mature Solution

Usual story regarding items that appear “too good to be true”. Credit where it’s due - with this app you can easily format a large-resolution image into multiple desktops, which has novelty value. But that’s as far as it goes. If you never change your desktop wallpaper this will be great for you! If you have a library of images and you’d like to be able to switch between them either manually or better yet automatically, this solution doesn’t help. You have to render a fresh image each time you want a change. The best solutions I have found have been a system of “left” and “right” images that I sometimes have to re-synchonise or using a matrox display extender to cast the dual displays as a single one - this having the disadvantage that it doesn’t seem to transmit sound. A bit disappointed all-round, really.

Hi Julia, Please give version 2.0 a go. It has a new auto-changer feature.
