I have a Lenovo T530 running Windows 10 Pro. My Lenovo is connected via Dockingstation to external displays through Displayport.

After installation of Displayfusion the Wallpaper function isn't working anymore. My desktop is always a black screen. When I change the wallpaper, the new wallpaper will be displayed for a few seconds, than the desktop is switching back to black desktop.
I tried to uninstall display fusion and and activate wallpaper again, without any results.

I have also searched in the web in another forums and tried so much things, without any results.

What I can do to fix this issue?
