So I've done some testing using a MacBook Pro 2017. All tests were performed using OBS 27.1.0 and Brio with Firmware 2.0.28, EEPROM 1.18 and Sensor 5.5

Observations:

Using cheap USB-C to USB-C cables limit the camera to MJPEG on 1080p/30f.
Using the Logitech supplied cable and an Anker USB-C to USB 3.1 adaptor (AK-848061067804) I can get 2160p/30f MJPEG and 1080p/30f NV12
Using good quality cables (e.g. Anker USB-c to USB3 / AK-A8169091) gives the same result as 2.
Using a 10Gbit certified USB-C to USB-C cable (e.g. Cable Matters 10gbit 1m ASIN:B01L0F6AJI) on both 10gbit or 5gbit USB-C ports will allow for 4k video with nv12.

Conclusion:

If you want NV12 or 4k resolution you need a quality usb3 cable that supports data rates at 480mbps.

If you need 4k and nv12 use a 5gbit/10gbit certified USB-C to USB-C cable.

Proofs Proofs Proofs I didn't like to down vote people, because I think that's not very mannerly or nice. I up voted almost everything, so if you didn't receive an up vote then there's probably something wrong with your answer. (Temporary Notice)I was in isolation for over 16 months, 12 consecutive months without stepping away from the apartment building, from Covid and it had significantly impacted my academic performance. Please be aware that I might not think clearly as I should be in terms of the orthodox academia reasoning. I started to study CFTs and string recently with the help of my advisor, it confused me as an developing subject so the thoughts and the elaborations are favored.

I got a Logitech Brio camera and wanted to set up for 4K video. However, somehow the 4K mode was recognized by the windows only with the original usb-c to usb 3.0 cable sent through the box.

I tried a usb-c to usb-c cable and usb-c to usb 3.0 cable by amazon. The windows was able to recognize it as a HD camera, but not a 4K one.

Why Logitech brio 4K mode only works on its own cable? Which kind of cable are compatible with Logitech brio 4K mode?

I have tried many USB-C cables; by Anker / Ugreen and I cannot get any to provide 4k performance. Maybe some weird shielding issue. Works perfectly with the logitech cable; but the design of that cable leaves a lot to be desired for my requirement.

Make sure the cable supports data rates > 480mbps

I lost my Brio cable and this answer saved me! I got an Ugreen US184 cable and it worked!
