Hi David,
The 4K on that dock is through the DisplayPort plug only, not through the HDMI.
Then, maybe the DP->HDMI adapter you are using is not 'active' enough. I've seen that with someone else last week whose DP->HDMI was supposed to do 4K but didn't. Changing to the Plugable DP-HDMI active adapter solved it.
Cheers,
Alban
