So if I have it set to extend to the second display it seems to work just fine. If I have it to show only desktop 2 (the external monitor) that is where I encounter the problem with the screen going portrait when prompted with UAC.

Repro.
Connect to USB External Monitor. I am using the Lenovo USB 3.0 Dock.
Set show on Display #2 (external monitor).
Log into machine as a non-admin
Do something to prompt UAC like opening Computer Management

I hope you are able to reproduce it now.
