Dell TB16 Thunderbolt Dock

Lots of posts on TB15 docks not working. I thought the TB16 deserved "a fresh start"... since it does work well (even though the AC adapter and TB16 dock are a Huge Kludge (and heavy!) compared to the HP TB3 Dock and AC adapter).

To install a TB16, use Dell Support Assist to update BIOS and typical drivers (DSA won't update any TB drivers until after TB drivers are initially installed manually), then, in this exact order:

1. Install the latest Intel Thunderbolt Controller Driver for the system. This is available in the "Chipset" section of Drivers & Downloads.
2. Install the latest Intel Thunderbolt 3 Firmware Update for the system. This is available in the "Chipset" section.
3. Install the latest Intel HD Graphics Driver for the system. This is available in the "Video" section.
4. Install the latest ASMedia USB 3.0 Extended Host Controller Driver for Dell Thunderbolt Dock. This is available in the "Docks & Stands" section.
5. Install the latest RealTek USB GBE Ethernet Controller Driver for Dell Thunderbolt Dock and Dell Dock. This is available in the "Docks & Stands" section.
6. Install the latest RealTek USB Audio Driver for Dell Thunderbolt Dock and Dell Dock. This is available in the "Docks & Stands" section.
7. Restart the system.
8. After the software update process completes, connect the AC adapter to the TB16 dock first and then attach the Thunderbolt 3 (Type C) cable to the computer before using the docking station.
9. A popup for a new Thunderbolt device will appear. Select "Always Connect" for both the Thunderbolt Cable and the Thunderbolt Dock. You can always navigate to the Thunderbolt device management by right-clicking the TB icon in the system tray, and selecting Manage or Approve.

The XPS AC adapter will not power the TB16 Dock: different DC tip sizes and wattage ratings.

 

Rather than packing the Huge Kludge, I highly recommend buying a compatible USB-C dongle if you travel with an XPS 9350, 9550, or higher. This dongle has proven very reliable:

This thing is completely useless -> 1 x HDMI@4K 30HZ and no Display Port.

 

It has a display port, or at least a mini DisplayPort which supports at least 4K@60hz (haven't tried anything else).

 

U sure? AFAIK only TB3 devices support 4K@60Hz.

The only reasonably compact TB3 thing I've seen is the Hyperdrive, but it has a mac-special dual TB3 input, its HDMI is again 4K@30Hz, up to 2x4K@60Hz only over TB3 output, requiring another DP adapter; And another USB dongle needed for wired Ethernet. I hope 3rd parties come up with more TB3 devices.

 

DisplayPort 1.2 supports it, don't think that 1.1 does however. At least I am running my 4K screen in 60 hz, both via the TB16 and from other computers having a mDP port.
