Alright, after poking around a bit I believe this is the same thing as
bug #828623, which is reported upstream so I'll dupe to that.

Bug description:
  Binary package hint: x11-xserver-utils

  While trying to connect external monitors through VGA in my Lenovo
  x201 with Intel HD Video graphics, gnome-display-properties fails to
  correctly display in the external monitors IF LVDS is set to off. If
  LVDS is kept on, then external monitors work correctly (Note that I'm
  not duplicating screens between LVDS and the external monitors).

  To reproduce, do as follows:

  1. Connect external monitor to VGA output.
  2. Launch gnome-display-properties and enable external monitors.
  3. At this point, both LVDS and external monitor should be working just fine.
  4. Using gnome-display-properties, turn off LVDS.
  5. At this point, the image in the external monitor looks like [1].

  Now, note that when disabling LVDS with xrandr instead of gnome-
  display-properties, then the external monitors have a correct image
  and [1] is not reproduced.
