Hi,

i have a  LG C9 with hdmi 2.1 ports, the TV is capable of 4K@120hz over hdmi2.1

I also have a 2080ti which has hdmi 2.0b

If i connected them with a CAC-1080 and used nvidia control panel to turn on adaptive sync as below.

https://nvidia.custhelp.com/app/answers/detail/a_id/4768/related/1

There is a feature which enables adaptive sync output over displayport

 

Can i get 1440p@120hz with adaptive sync (VRR) working?

Hello Pittyh,

Thank you for your question. The answer is no i’m afraid, Adaptive sync at 1440p@120 will not work.

Ok thanks mate, hopefully the displayport 1.4 to hdmi 2.1 adapter you “may” or “may not” be working on will fix all the issues. 😛

 

Thanks.

Hi,

The option to use VRR is not possible with the cac-1080 due to lack of bandwith.
