Just wanted to give a heads up that I can’t run 3840×2160 @ 120hz with the latest 511.65 driver. I posted at the Nvidia forums and submitted a driver feedback form with all of the required data. Going back to 511.23 solves the issue for now. I’m using the LG CX 48″ OLED connected to the CAC-1085 adapter.
They released a hotfix it seems. Did this resolve this issue?
I just checked with my setup RTX2080TI and a C9. With the new drivers of Nvidia I get 4K120Hz RGB no problem.
Do you know what Firmware you have on your CAC-1085. When did you buy it? You might also send [email protected] an email. They will help you.
Yup… They broke it again… Just updated from 495 to 510 on Linux (510.47.03), and 4k@120 is gone. Nvidia settings app reports connection link as 4 lanes @ 5.40Gbps, when the previous drivers reported 4 lanes @ 8.10Gbps.
There are quite alot of issues with this new driver of Nvidia it seems.
Nvidia release new drivers (again) check them, might fix the issues.

Going back to driver 511.23 solved the issue for me too. I’m using RTX 2060 Super with LG CX
Thanks for this info! I can confirm that this version of drivers works great with RTX 2070 Super with the CX as well.
Hellblade: Senua’s Sacrifice looking awesome AF in 4K HDR, balanced DLSS, and 4K easily sailing @ 75 FPS 🙂
When did you purchase your CAC-1085? It might be you a have an older firmware version.
