--- Comment #9 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
Looking at the VBT we see the port:
        EFP device info:
                Device handle: 0x0020 (EFP 3 (HDMI/DVI/DP))
                Device type: 0x60d6 (DisplayPort/HDMI/DVI)
                        Power management
                        Hotplug signaling
                        HDMI output
                        Content protection
                        High speel link
                        TMDS/DVI signaling
                        DisplayPort output
                        Digital output

So it clearly claims that the port is capable of DP output. Which is why we
think that it's a DP++ port as opposed to a HDMI port.

It does claim to be an actual HDMI port in the actual port information:
                Port: 0x03 (HDMI-D)
however we can't really trust that information since there are other machines
out there that have ports claiming to be HDMI like this, but are in fact DP++
ports.

So at the moment I can't really see any way we can win :(
