I have multiple screens, some are 23" 1920x1080 screens, and one is a 28" 3840x2160 screen, and another is a 32" 1920x1080 TV attached. This means they have a different pixel density and if I span an image across them, it won't take into account the bezels between screens and the size difference.

Is there anything I can set in DisplayFusion to set the size and positions of screens, instead of it using the resolutions as sizes?

I can handle this problem by messing with scaling and adjusting the position of the background manually, but it's kind of a pita to get that all adjusted just right.
