Get monitor arrangement to obey DPI scaling rules?

See image

all 3 monitors are the same physical size (24''), but the middle one is a 4k monitor with DPI scaling on.

So far everything is working MOSTLY correct (ok like 60% correct), except when moving the mouse between monitors, windows 8 still assumes the middle one is twice as large, so I can only move the mouse between screens if I move it to the bottom half of the middle monitor

Is there any way to fix?
