I recently added a fourth monitor to my computer. In addition to my main/middle monitor (3440x1440) there are two portrait (1080x1920) side monitors and now the top monitor (3840x2160).

My issue is that physically, the center monitor is wider than the top, but the horizontal resolution is -200 pixels less than the monitor above it. This is an issue because I am a die-hard "top taskbar" person, and the mouse management option to "Prevent mouse curso from snaggin on unaligned monitor edges" only considers the screen resolution. I also control a laptop (below middle monitor) with the software KVM Multiplicity, so all four sides of the main monitor transition to another screen.

This is how the monitors show up through DisplayFusion Monitor Configuration:



However, physically it is more like this (photoshopped) arrangement:



I'm not finding any Windows or DisplayFusion settings that will let me consider the physical size rather than resolution. My ideal outcome would be some way to prevent the mouse traveling from the center to top monitor in the top corners where they do not line up.
