Dell Precision 5520 + D6000 Dock + Panasonic 328P = MAX 30HZ

Couple of things come to mind:

1. Check your monitor OSD is set to to DisplayPort 1.2 and not 1.1
2. Check 60Hz is set in the Display adapter properties > "List All Modes" option:

Changed the settings on the monitor and rebooted and now it's listed.

Thanks for the help.
