What content is streaming at 120hz? Otherwise, 4K 60hz HDR is fine on 2.0
4K 60Hz HDR is still limited to 8 bit color, which is unsuitable for HDR. You'd have to go down to 30Hz to get 10 bit color on HDMI 2.0.
Meanwhile with this patch, I can do 4K 120Hz with 12 bit color.
It's only limited to 8 bit in 4:4:4 color space. It can do 10 bit 4K 60hz in 4:2:0 color space, which most things are streamed at because it is such a bandwidth saver.

4K 60hz is about 18GB/s and it's being sent down a 1GB/s pipe typically when streamed. You're not getting all the data. It's really compressed to fit and the color space is usually set to 4:2:0 to again save bandwidth.
But you said 120hz
so that would need twice the bandwidth of 60hz, meaning even more compression.

Lol, streaming. Paying for multiple subscriptions. Passively consuming media.
