I’m familiar with that thread. I have a C1 tv which I wanted to use with an Intel iGPU at 4K120 HDR. The Intel HDMI output can only do 4K60 outside of Wndows. The iGPU’s dp does work at 4K120HDR. Out of curiosity, I also confirmed it works on a 7900xt at 4K120 HDR. I did this on Kubuntu and CachyOS with Plasma on Wayland
I used this cable: https://www.amazon.com/dp/B0D7VP726N
Not an ideal setup as HDMI 2.1 had slightly more bandwidth which translates to better picture quality, but it works better for me
