I have the CAC-1085 adapter with the following setup and I cannot get the 120hz option to show up no matter what settings. Any help would be appreciated. 

Adapter: CAC-1085 USB Powered by own power supply as recommended

HDMI Cable: CAC-1372 2m

Graphics Card: 2080Ti

TV/monitor: LG C9 latest firmware

Video Drivers: 456.55

Hi Solofx7,

If you downgrade back to Nvidia's 456.38 drives it should work again.

Hi Solofx7,

Even 456.71 driver works. At least it works with my 48CX. The issue is registered as open issue since 461.40: Displayport-to-HDMI 2.1 protocol converter clock limited to 600MHz pixel clock [3202060].
