The two monitors plugged into the display ports are showing up as DP2 in xrandr, instead of separate monitors. The VGA shows up as a separate monitor just fine and I can configure it separately (though it only shows up when I reboot).

The only way I can get them to work right is to have them combined into a single display (i.e. a resolution of 3840x1200 instead of two 1920x1200 displays). This is hard to work with since I can't maximize a window to just that monitor, rather it maximizes to the whole display.

Your dock is probably a DP MST device and so needs at least kernel 3.17 to
work properly. And the support is still wip, so might run into issues.
Iirc you also need an upgraded Xorg.
