Can you check if you have a mass storage which is not from another USB key you plugged in your computer?
Alternatively, install the 8.0 M2 previously linked and, if you get your monitor back, then it was NOT a mass storage.
Kind regards,

I installed M2 but it did not help. It looks like I will need to roll back to the previous version of Windows 10.

The device is a Toshiba Dynadock-U and there are no mass storage devices plugged into it.
