I have set DF Pro 8.0 for the wallpaper to to "fit best and maintain aspect ratio (no clipping)" with a different image on each monitor. This works on my primary monitor (Dell U3214 @ 1920 x 1200) but on my secondary NEC PA231W @ 1920 x 1080, it preserves the aspect ratio but never clips, near as I can tell.

My wallpaper images are a set of well-known paintings, so I don't want to change the aspect ratio and I don't want clipping.

I have searched in DF and in the forums, but have not found a solution.

Any ideas?
