It would be awesome if we could load wallpaper images according to Portrait or landscape aspect ratio. I have 2 monitors, one is vertical and one is horizontal, I would like it to automatically load only vertical aspect ratio images on the vertical screen etc.

I came to request the same thing. Multi-monitors of mixed sizes is pretty common now. It would be nice if my wallpaper fit to the matching portrait or landscaping ratio. I realize I could sort through all my wallpapers and split them in to separate folders based on size, but... it seems it would be a simple calculation for DisplayFusion. Thanks
