<pre>Notebook: HP EliteBook 840 G1 (Core i7-4600U, HD Graphics 4000)
Docking station: HP UltraSlim Dock 2013
Monitors: 2x Dell U2414H (1920x1080, DisplayPort)
Software: Linux 3.15.1, X.Org 1.15.99.903, xf86-video-intel 2.99.912
The docking station has two DisplayPort connectors. Both are connected to an
external Dell U2414H monitor. But GNOME and xrandr only see DP1 but not DP2.
(And for some reason the first external monitor is mirrored on the second
external monitor.)
