Missing HDMI1 in xrandr after system update

Hey archlinux crowd,

I am running arch on my (now 4 month old) Samsung Ultrabook NP940X3G.
It worked out-of-the-box immediately. Nice!

But probably a month ago a system update (which included intel drivers) shredded my external port. HDMI1 was missing from xrandr, instead DP1 and VIRTUAL shows up in addition to eDP1 which is the actual laptop screen.

I tried to investigate but stopped soon. Eventually, another system update a week later fixed the problem.

Now, after updating the system two days ago the same error occurred again. Reboot and HDMI1 is replaced by those mentioned fellas.

Anyone with similar problem or ideas?
