First post - I've been using DisplayFusion since getting a laptop capable of driving two external screens and the internal all at once. DF has certainly made life easier for wallpaper management!
My setup has a matched pair of 23" screens side by side, with the 15.4" laptop beneath. I have (L-R) monitors 1&2 combined with a dual wallpaper stretched over, shuffling between by collection, with monitor 3 as a standalone random Interfacelift backdrop.
My issue is there's a significant softening of my dual wallpapers, which was never an issue with my previous wallpaper shuffler (JBS). Is there some compression going on or a stretching issue I can't work out? See below for a couple of 1:1 comparisons between the desktop and Windows photo viewer. I know it's minor, but I'm only 24" away from my screens, so I want to see my wallpapers as intended!
This is unfortunately an issue with the .NET image library. DisplayFusion has to take the images for all of the monitors and combine them into one large one. Even though we tell it to generate the image uncompressed, the .NET image library still seems to manage to blur the image a bit. At some point we may find a different image library to use, but for now, this is just the way it is, sorry
