Is there a way to turn this off? I've looked everywhere and one post said "Advanced settings in the very bottom" but I have no such option. DisplayFusion keeps telling me this because I have some old games, and I don't want it to change my desktop background's resolution because it'll fix itself when I quit those games either way.

Tried this but it still asks me if it wants to fix my wallpaper for new resolution.

That option was exactly what I was looking for, and what I wanted to turn off in the first place. So now I found the option I was looking for.
