But I'm not sure how much practical value it adds? 4K120 8-bit 4:2:0 over HDMI's TMDS signaling system is out of spec. It's not fit for the PC ecosystem (8-bit RGB levels) and not fit for the video ecosystem (10-bit HDR).
Ah, so you did see it demonstrated, awesome!
And it does add a significant value to gaming, going from 60Hz on something like my B7 to 120Hz is a huge improvement (I had a Samsung Q950 for a week before returning it, and have tested a Q90 as well, and while they were absolutely horrible for computer use in many ways, the 4K 120Hz gaming experience was great). 8-bit color depth is still common in high refresh rate gaming, so it's not really a big difference compared to the norm, and the graphical quality losses of 4:2:0, while not insignificant, often aren't that much of an issue in gaming.
The biggest part of it is that you can enjoy the 120Hz right away, without waiting for and having to buy a new GPU as well (whenever those eventually come out), and since they do support HDMI 2.1 you'll be ready to move to that when you eventually do update your GPU. For someone like me, the C9 wasn't really a compelling upgrade, because I'd essentially only be getting G-sync (which, while great, isn't something I'm super concerned about), and would be stuck on 60Hz until new GPUs land and I could afford to get one of those too (1440p120Hz isn't really an interesting upgrade over 1080p120Hz of the B7). OK, the input lag is also better, but still.
The CX however really interests me, being able to run 120Hz at the TVs native resolution without other system changes would be a great upgrade to my B7. If C9 had supported it I would have bought one ages ago.
