Is it Thunderbolt 3 or Thunderbolt 4?

Also note, the DeckLink Quad 2 is a x8 PCIe 2.0 card, and the Sonnet/Thunderbolt 3 essentially supports x4 PCIe 3.0 lanes and so while the bandwidth is there, it could possibly struggle to support the 8 lanes the card is looking for.

Yes, there certainly is a lot of confusion around the complexities involved with Thunderbolt 3 vs Thunderbolt 4 and the equivalency bandwidth of x1/x4/x8 PCIe lanes and/or the generation of PCIe 2.0/3.0/4.0 being used.
As noted above in the "compatibility chart" link, Sonnet does support the Decklink Quad 2 with Thunderbolt 3 connections, but what I wanted to bring to your attention is that there are other factors further down the line that could affect the performance and/or reliability of using a x8 card with an expansion box.
The bottom line is, you are likely to hit a bottleneck sooner or later depending on how all your "ducks line up" for your particular situation.
I would certainly expect the card(s) to show up, but just how many cameras you will successfully be able to squeeze out will depend largely on how your computer is configured to handle all of the above and why vMix itself does not recommend/support more than 4 cameras from external Thunderbolt devices, which x4 PCIe 3.0 via Thunderbolt 3 can easily handle, but there are too many variables to consider if you try to go beyond that.

Unfortunately the SE I is not compatible with the Quad 2 according to the specs sheet on the Sonnet website - if you have different infos, dis-le moi ;)


Yes - tried various versions of the Desktop Video software

Never had the possibility to do it, as the card was not recognised as sucg


This is the next step

Probably yes...

Hi mbuerel,

I hade similar problems with my declink quad 2 an a new TB4 notebook.

In the past I used a HP Omen with TB3 and the decklink quad 2 in TB cases (Decklink Quad 2 in Sonnet Echo Express SE1 & ADT-Link
R43SG-TB3 / Decklink Duo 2 in Highpoint Rocketstor 6661A & Zotac AMP mini) and could use all 8 inputs in 1080p50. (Decklink is PCIe 2.0 x8 (4 GByte/s), which has nearly the same speed as PCIe 3.0 x4 (3,9 GByte/s))

With the switch to a new XMG Focus i9-13900HX/4070 Nvidia/2x 2TB NVME SSD/TB4 notebook the card wasn't recognise by the system under Windows 11, tested different TB cases, so no case problem.

How I got it finaly to work:

1. Downgrade to Windows 10

2. Install Desktop Video 12.7.1

3. Deactivate all internal Network connections (LAN/WLAN) in the Control Panel. (In my case they haven't worked parallel to the Decklink Quad 2)

4. Use a USB LAN adapter with a Realtec chipset to have a LAN connection.

5. Connect the TB4 case when the system is up and check if all inputs show up in the control panel. (If it is connected during startup, the driver will stop the card.)

It doesn't feel comfortable, but it worked for me and I had not much time to sort out if it is driver or hardware problem. I did a few sport streams with 8 cams (7x SDI/1x NDI) in 1080p50, replay of 6 cams, overlays for statistics, Streaming 12 MBit/s, local recording in MP4 with 16 MBit/s and a multiview SRT out with 6 MBit/s ( )
