Question about Microsoft Surface Dock 2

Switching to a USB-C to Displayport cable might help if your monitors have Display Port. The USB-C-HDMI adapter is active (one device in between, the usb-c - displayport cable is direct so you have eliminated one source of error.

I also had this problem. Try deleting the display chat and then reconnecting. https://download.microsoft.com/download...

Hello

I also have a Dock 2 and also had a problem with the recognition of the USB ports (but I can't remember exactly what).

I solved the problem by installing a power strip with a switch. I use it to switch off both the monitors and the dock. The quasi-restart of the dock apparently solves the problem.

Hope this works for you.
