Issues with Plugable USB-C UD-ULTC4K Dock

[Jeff29922]

I am having a similar issue, but it's only the monitor that is connected to the dock via HDMI. I am using the dock with my Surface Book 2 and I believe that this is a known issue. I opened a case with Plugable and they sent me a new dock (supposedly with newer firmware) that was supposed to fix the issue, but I have the exact same symptoms with the new dock. I have updated all related drivers (Microsoft Surface Book 2, Dock, etc.) I think I will have to open a case. I am also a Microsoft employee so I will check to see if this is a known issue and if anything is being done on our side (I know there are other SB2 owners having the same problem). Sorry I know you have a HP, but it's now looking like there is an issue with the HDMI port on the dock and it might not be only with the Surface.
