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.

    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.
