Well... It took me a few minutes, but I figured out how it worked!!!! Desktop fusion, apparently, creates a JPEG image that spans both monitors (in my case 3840x1080) and saves it then sets it to display with the "tile" configuration.
One thing I noticed is that monitor 1 has to be to the left of monitor 2 (physically) for the picture to show properly... Monitor 2 in my setup is on the left... The way I got around this was by cutting the picture in half and attaching the halves opposite each other...
EDIT: Display Fusion is a bit easier and quite a bit less frustrating though!!!
Laxer... Do you use the paid version or the free version with limited functionality?
