Issues with CAC-1376 and 3080 Ti on LG OLED C9

I’m trying to find a solution to get HDMI 2.1 working on my OLED C9 with my new Gigabyte 3080 Ti. I’ve tried the CAC-1376 but it didn’t work. I didn’t even get 4k 60Hz and HDR. Everything that goes beyond 4k 60Hz results in the loss of signal. I’ve used a similar HDMI 2.0 cable with my previous card a 2080 Ti and that worked flawlessly with 4k 60 Hz and HDR. But the new gpu doesn’t manage even that with either the old cable or the CAC-1376. I’ve suspected the gpu might be the issue but I don’t really know, I’ve also contacted Gigabyte and am here now to maybe find someone who might have the same or similar setup/issue and could provice some help. I feel pretty lost having spend all this money on an upgrade that feels more like a downgrade right now.

Thanks in advance!

Hi so the HDMI cable that was able to do 4K60Hz on the TI2080 gives you the same problem with RTX3080TI? That seems an issue with the GPU – what is the PSU that you are using?
