BTW, I love DisplayFusion and it is definitely helping me be more productive in my daily tasks.
Problem: To make my wallpapers feel more like seamlessly looking out of a window on my triple monitor portrait-mode setup I use DisplayFusion's equivalent of ATI's Bezel Compensation by applying image-position adjustments on left and right monitors (125px feels right on Dell U2311H) and apply image scaling (107% here) on all monitors to compensate for image data loss. I use "Fit Best and maintain Aspect Ratio (Clip Edges)" and while it works for most images it still leaves me with many wallpapers that do not fill up the whole screen real estate, leaving bars of varying width on either sides of the central image. Nitpicking, but distracting.
Hack: The only way I have managed to make wallpapers fill up my 3 screens while compensating for bezel thickness is to either use images that are at least as high as my monitors and wider by a few dozen pixels than the combined width of all monitors, or to crop images from smaller pictures so that they have a non-standard aspect ratio of 1.7 or more. Kinda long an annoying.
Proposition: Modify option "Fit Best and maintain Aspect Ratio (Clip Edges)" to zoom the image sufficiently to fill up all monitors completely while accounting for image-position + image-scaling settings.
