How come DisplayFusion only considers resolution when spanning an image across monitors? Images will always mismatch if DPI is not considered.

I've tried spanning an image or combining monitors to span an image but it appears impossible to actually configure a wallpaper that will exactly match across screens.

LittleBigMouse (image attached) can perfectly predict the ratio's of the screens to each other, DisplayFusion (image attached) is completely off.

I would expect this to be default behavior or at least have a setting to fix this behaviour. Is there anything I can do?

In Little Big Mouse it shows me the real world relative size and position of the monitors. As you can see I have a 24" and 27" display next to each other and have a real world surface area ratio closer to a 1.25:1 rather than the 4:1 when you're just considering pixels (4K vs HD).

The misalignment across screens is quite jarring. I hope it will be patched soon.

Not sure if there's a place to vote for the feature or otherwise bump this, but I desperately need this feature with DisplayFusion. I have a 1920x1080 32" on top of a 2560x1080 ultrawide and neither stock Windows nor DisplayFusion can figure out where the heck the monitors are supposed to cross over each other.

Thank you!
