When I use the CAC 1085 for 3 individual 4k 120 tv’s, I can get them to work in the windows display setting. Nvidia Geforce Control panel also shows each individual tv as 4k 120hz.

However, when I try to activate Nvidia Surround for triple monitors, I can’t get the 12288 x 2160 to lock in at 120hz. It has the option, but when I select it, the screen goes black and then reverts back to 60hz. Has anyone figured out how to do 120hz with surround?

Strangely, when I ran the triples individually at 4k 120hz, the monitors look blurry when using iracing. Using Nvidia Surround at 4k 60hz looks clearer. Should that be the case?

I am using a 3090 FTW EVGA card.

Hi Achilles99,

Can you try and downgrade your Nvidia drivers to 456.38 and see what happens?

How long are the cables you are using? In combination with the CAC-1085?

Even then, I think that 12K120Hz is not possible over the 3090… Might be an option to ask this question on the EVGA forums as well.

Insert Image Size must be less than < 5MB.

Hi, i can confirm that 12K@120Hz is posible with 456.71 and 456.98. Drivers 457, 460 and 461 series only enable 12K@60Hz.

I own a Gigabyte AORUS Master 3090 connected (in surround mode) to 3 x LG OLED 55 C9.

For that im using 2 x HDMI 2.1 output in 3090 and for the 3rd output i use a Club3D CAC-1085 DP 1.4 to HDMI 2.1

I sended a display driver form in nvidia explaning that. No response of course, but it could be a change in DSC 1.2 implementation at driver level, who knows…..

Hi Linfatyk,

I’m not jealous at all….

Happy to hear it works like that.

Funny, Linus just did triple 4k surround 🙂

4k 120hz doesn’t work with Nvidia Surround Triples, but works separately?
