Hello all. I have a Studio display that I am trying to get working better with my Windows 11 machine.

I have this cable - which is working great. Audio and the camera work great too.

I am on an i7 with an RTX 3070TI and I can't seem to get brightness to work.

I downloaded the dedicated brightness control here https://github.com/Chris-Poland/SDBC and followed all the instructions to install vid:05ac pid:1114 rev:0201 mi:08 from ibusb-win3. Yet, I still get a red line in the brightness controller indicating the PC is not connecting w/ the monitor. Any one have any tips? Maybe my cable is incorrect?
