Dell TB16 Thunderbolt dock with DL-165 adapter

[AlbanRampon]

The TB16 is using proprietary hardware and software... TB stands for Thunderbolt which requires an Intel Thunderbolt controller in the host. There's not many non-proprietary active graphics adapters in electronics.
He already has the adapter. I don't see why you're suggesting he spends more money without looking into the problem first.

OP,
I would need to see the logs to understand why the driver doesn't start properly.
Maybe you are using Windows 10 Anniversary Update, maybe there's something else.
The last link in my forum signature explains how to gather logs. You can post the zip here as only employees can download them.

Kind regards,
Alban
