1. Can you connect the Samsung monitor to the DisplayPort video output port on the back of the UD22 dock, specifically the one that is closest to the dock's Ethernet RJ-45 port?

2. The Plugable product you mentioned is based on DisplayLink technology. Do you still have the DisplayLink Manager Application installed on your Mac?

1. Yes, I've tried all 3 ports, HDMI and both displayports. I am plugged into "displayport in" on my samsung monitor, there is also a "displayport out"

2. Yes, still installed version 1.10.2 (building 14)
