Skylake ThinkPad Yoga 14 (20FY) mini displayport won't work.

I picked up a Skylake yoga 14 (model # 20FY0002US) and I'm not getting anything from the DVI or HDMI outputs on a mini-DP to HDMI/DP/DVI adapter.


This is the particular adapter I tried:


To be clear, the adapter offers DVI, HDMI, and DP outputs, only one of which works at a time. I'm not trying to plug three monitors into it. However, if I hook up a monitor via either the DVI or the HDMI outputs, the computer freezes for 15-60 seconds and nothing shows up on the external monitor.


Drivers are all updated. I've tried the adapter on a Surface Pro 3 and it worked flawlessly. I've also tried it with multiple external monitors, so the problem is definitely with my ThinkPad. I've also tried DP1.1 and DP 1.2 versions of the adapter. Again, nothing out of the DVI or HDMI outputs.



Oddly enough, when I tried a simple mini-DP to VGA adapter, it worked. 


What gives? This is a pretty important functionality to be missing...
