No signal to 2nd monitor when laptop lid is open - ThinkPad P50 and Ultra Dock 40A5

When the P50 is docked with the lid closed, my two Dell 23" monitors (P2317H) connected via  2 Display Ports both recieve a signal from the dock.

 

When the lid is opened, one monitor will lose signal.

 

I have updated the Nvidia driver on the P50, as well as the firmware on the dock, which did not resolve the issue.  I have also tested this with a differnt P50, dock, monitors, and cables with the same result.

 

OS: Windows 10 64-bit

Hardware: Lenovo ThinkPad P50, Lenovo ThinkPad Ultra Dock 40A2, Dell 23" Monitors P2317H
