I'm using:
Win10 guest
Parallels 13
2015 Macbook Pro with OSX Sierra
I don't have any major problems with multi-monitor as described by other users. However, I have noticed that when the mouse transitions between monitors, OSX grabs it (it becomes black). Normally the mouse arrow is white under Windows. I can see that Windows is still getting the mouse position, because there's a white arrow underneath the black arrow. So it's as if OSX and Windows are both using the mouse, after I transition monitors, without clicking. If I click inside the 2nd monitor, mouse control is returned to Windows and the black pointer disappears.
This is pretty annoying because I always have to click twice after moving my mouse between monitors. It also causes strange things to happen when dragging items across monitors; it does work, but it looks like OSX and Windows are both interacting with the dragging function.
