I have the same problem, I'm at my second docking station, the only thing that work is charging.
I stopped at the Microsoft store, they tried everything, no luck.
Apparently it's the contacts from the dock to the tablet, something in the tablet plug is bad. They ask me to reset the surface pro 3 to find more about the problem, but first I want to be sure everything is backup, then if that doesn't work, they will exchange the Surface. So I will know more during the coming week.
On my second SP3. I highly doubt the tablet connection is the problem. Beware of what they tell you at the Microsoft stores - most (but not all) of the employees are clueless.
