Did you find any fix? I am having the same problem. My port is working but its displaying only static and sometimes current display split in half with static in between.
I contacted Microsoft Support but they said its maybe a cable issue, so I bought a new cable but its still not working, then they said to revert the current build and upgrade it again, tried it 3 times; not working.
I dual booted into Ubuntu 17.10 and it works... It also works in previous build...
I am using Dell Inspiron 7560.
