Certainly have. Was the first thing I checked. Latest drivers are also installed per the Lenovo Vantage tool.

Thinking about this more - there was a firmware update that flashed the dock. How can I check that it is running the latest? All I can tell is the update utility says there are no updates available.

Ok, so issue is now resolved. There was a Thunderbolt firmware update released this week that fixed the problem. 4k resolution now available.
