Triple 120hz monitors

Hi All,

I am about to buy 3 LG OLED55C 4k TVs for my sim racing rig. They will be plugged into an RTX 3090. The 3090 has 3x displayport 1.4a and a single HDMI 2.1, and the TVs have HDMI 2.1 and run @120hz. I want to end up with 3 monitors all running 4k @120hz.

What do I need as the solution please? 3x adapters? Some kind of splitter?

Many thanks in advance.

I’ve also read that the adapters stop the gsync from working. Can anyone confirm or deny this please?

First question you need to ask Nvidia or the manufacturer is if the RTX3090 supports that kind of resolution. Even before you buy the 3 LG CX’s.

Gsync does not work with the CAC-1085, correct.

I don’t know if 1 native HDMI 2.1 + 2 adapters will work. Because of the Gsync. Nor can I confirm if 3 x CAC-1085 will work due to the first question.

Thanks Baak.

According to a LTT video I watched, they had a 3090 running triple 4k@120hz so I’m going with yes.

I’ve seen that too, but they use DisplayPort directly. Without an adapter. Technically it should work yes. But don’t take my word, I don’t have a 3090 (cries in RX6800XT :P)

Maybe ask [email protected] ?
