TBT3-UDV & MBP2016-15 how to connect dual 4K displays?

TBT3-UDV & MBP2016-15 how to connect dual 4K displays? I may have misunderstood the specifications when I purchased this dock. I have two 4K displays with DP connectivity. One is working fine via the TBT3-UDV’s DisplayPort.

I connected the second display to the TB3 downstream port but this monitor is not working. I thought the Plugable USB-C to DisplayPort Adapter Cable I purchased with the TBT3-UDV would allow me to do this, but I now realize I may be wrong.

What do I need to purchase to connect the second monitor via the dock’s downstream TB3 port? Will the Plugable TBT3-DP2X-83 get the job done?


Sorry, my problem was user error! The USB-C cable in my second display had come loose. Reseating it solved my issue. I may need to look for a USB-C to DP cable that has the captive connector at the DP end.

Thank you.
