<span class="quote">> When I plug in an external monitor, xranrd shows it as connected
> to DP2, regardless of whether it's connected to DP1, DP2, DVI or HDMI.</span >
>From how I understand it, this is because all the display connectors are
provided through a DP MST hub that is working in the dock. This hub then
provides three possible outputs (VGA, digital group 1 and digital group 2). We
need DP MST support.</pre>
