USB C to Mini DisplayPort Adapter

Does qnyone know if it is possible for a Meta Quest 3 headset to be connected to a GPU using a USB C to mini DisplayPort adapter? I am upgrading graphics cards and the new one would only have 4 x mini DisplayPort connections on it, no USB C connection. I’m no sure if this adapter will work with a Meta Quest and Link cable however?

I did email Meta and got the below reply but they don’t sound certain:

”I may suggest you to have a convertor of USB C port to Display Port. However, it is not recommendable to use an extension but if it is not connected you may use an AirLink to connect your Meta Quest 3 to PCVR.
Answering your question, any graphic card with RTX 4000 series will always be compatible with your headset Meta Quest 3. You may click on this link on the requirements to use Meta Link.”

in this case, I have a workstation graphics card, Nvidia RTX 4000, does have a USB C connection but the newer card RTX 4000 ADA just has 4 x mini DisplayPorts on it.

The Quest 3 has no understanding of DisplayPort. All it wants is pure USB data sent directly from the Quest app. An adapter for display port to usb wouldn't understand the data format required, and you couldn't send the tracking and controller data back to the PC through a display port.

Luckily a USB C port on the gfx card isn't needed, it's only being used as a regular port anyway (I connect a webcam or charge my phone using my 2080TI's USB port with the Oculus link cable). You can connect a Quest 3 to any USB 3 port on your computer, either USB-A or USB-C, as long as you have a good cable for it. The official Link cable is fibre optic to get better length, but you can get good USB-A to USB-C cables for Link from Amazon with an active repeater in them (to get to reliable 5m length).

(Geforces with USB did have a special mode for high quality VR direct output, but almost no headset ever supported it, and Meta never did. Sadly)
