Help With Multi Monitor Wallpapers

Ok so to start off I had no idea what category to put this in so if an admin or mod would like to change the category to the correct one that would be great. Now, my problem. I was running a dual monitor setup for a while and had dual monitor wallpapers working fine but I recently found an app that allows me to use my iPad as a monitor through usb. The issue is that it changes changes my current dual monitor wallpaper to fit the ipad monitor and it ruins the image. I want to keep the dual monitor wallpaper for the two original wallpapers and have a different wallpaper for the iPad. I've combed through the web for a few hours now trying out different programs and I've found none that can let me do this, so any suggestions?

display fusion?

never heard of that

Its called twomonusb, and also does display fusion have a dedicated free version or just a free trial?

yes
