Zbook Workstation
Microsoft Windows 10 (64-bit)

I am having issues connecting 4 external monitors to a Zbook 15 G3.  The Zbook has a 3840 x 2160 monitor and is connected to a Thunderbolt 3 dock.  The external monitors I am trying to connect are all 4k 3840 x 2160 monitors and have 2 HDMI ports and 1 DigitalDisplay port.  The laptop has 1 HDMI port, 1 USB-C port and 1 DigitalDisplay Port.  The thunderbolt dock has 2 DigitalDisplay ports, and a USB-C port.  I can get three monitors to work in addition to the laptop monitor but no matter what I try, I can't get the fourth monitor to work.  I have even tried DigitalDisplay adapters with 2 and 3 hubs and even a USB-C hub with two DigitalDisplay ports.  

 

Any help would be greatly appreciated.
