Thinkpad P1 & Thunderbolt 3 Dock / 40AN0230US - No 4k?

The Thunderbolt dock is advertised as being able to use multiple 4k displays. I have one 4k display connected via displayport, yet max resolution available is only 1080/60. 

I have the lid closed on the P1 and only one 4k display connected. 

 

Apprecaite any help. thanks

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.
