I use a CAC-1087 but i m not able to get 4k120Hz working. Above 1080p the limit is 60Hz that the adapter is able to put to the TV.
Setup: Windows 11 on AMD Ryzen Threadripper 3970x > ASUS ROG ZENITH II EXTREME > Nvidia RTX A4000 (Output:DisplayPort) > CLUB 3D CAC-1087 > LG OLED42C24LA (Input: HDMI)
How on earth do these Adapters behave so different?
I tried the settings above… no chance to get 4K120Hz signal on the TV.
If i add a CAC-1085 on another DisplayPort on the RTX A4000 and connect it to another HDMI Input (E.g. HDMI 2) of the TV, then the following setup works:
Clone the Display 1 and 2 via Nvidia Control Panel, set Display 2 (E.g CAC-1085) as primary and resolution to 4K120Hz then the TV is able to get Input Signal also on HDMI 1 (via CAC-1087). As soon as i remove the CAC-1085 everything drops back to only 4K60Hz possible.
Will a Firmwar Update of the CAC-1087 help me to use only the CAC-1087 with 4K120Hz?
