DELL Precision 5520 with TB16 dock 4 monitors


I have a DELL Precision 5520 with TB16 dock.  

I have 3 monitors and the laptop screen.  1 of the monitors is connected with a Display Link adapter (with drivers installed).

All 4 monitors are working, sometimes.  The laptop screen randomly shuts off/is disalbed (and shuffles all the displays around).  If I unplug the docking station and plug it back in, the laptop monitor starts working again.

I have done a lot of searching and everything says the dock supports 3 monitors and if I have something like the Display Link, I can have 4 monitors. 

What do I need to do to make this work and have the laptop screen stop shutting off?

The screen runs for an hour or more before being disabled.

My monitors are all 1920 x 1080 resolution and the laptop is the same.

I updated the docking station to the most recent drivers and the Display Link software should be the most recent version (8.2.1491).

Any help would be appreciated to make this work.
