Everything works just fine. Even the Gigabit Ethernet port works quite fast (only slightly slower than that in the notebook).
Unfortunately, one gets added only one USB 3.0 port, as only two USB 3.0 and two other 2.0 are of the 4 USB ports. This is a point deduction.
Also unfortunately, the full resolution is only supplied via the DisplayPort. The DVI connector seems to be a dual link, so only normal resolutions work. That is another point deduction.
Also works at full resolution only the connection of a monitor to the docking station. For two monitors is 2560x1440 no longer possible.
