Display Dialog: Call for Testing

[samuel]

observations for 3 screens.

1. My monitors are named wrong. Somehow the screen in the middle got
the name of the screen on the left and the screen on the left got the
name of the screen in the middle.

2. The dialog seems to confuse right-of and left-of with above and below.
In reality i have:
Screen 1 left, Screen 2 middle, Screen 3 right (rotated left)
On the dialog:
Screen 1 (above of screen 3)
Screen 2 (above of screen 3)
Screen 3 (below screen 2) (rotated left)

I haven't tested anything else. Maybe first try to fix this?

If you need more info just ask.
