    ok so I looked into this last year but I have completely forgot haha.

    So these LG OLED C9 and B9 should drop in price now the new 2020 versions have been released so I might pick one up.

    can I actually play games at 120hz 4k?

    I think I remember the HDMI on the GPU isn’t compatible?

    what’s the best spec I can run these TVs at, I will be sat around 3meters away.

    With current GPUs you're stuck at 4k60 or 1440p120 (I've not tested this on mine). As you rightly say, we're waiting for next gen GPUs with HDMI 2.1 to allow us to use 4k120

    1440p @ 120hz isn't too bad. There is a way to get 4k @ 120hz "working" but it appears to just be upscaling from 1440p, so whilst it may look a bit better it's still not the real thing.

    3m away is quite far. I doubt you'll see the difference 1440p vs 4K unless you're buying the 77". Hell, I sit maybe not even half that from a 55" and in some games not even then do I notice the difference (rare but becoming common, eg temporal reconstruction games like Division 2 etc).

    Imo if you get a good deal on a B/C9 then don't fret about not having 4K 120hz today. HDMI 2.1 GPUs are only a few months away. ;)

    Not according to this video, he is using a C X (10) 2020 Model but I can't see how it would be different.Maybe different firmware?

    He's talking rubbish, when in MW settings it says render res is 1440p

    It's artificial segmentation by LG. You can do 4K 120hz @ 8-bit 4:2:0 on the CX, but not on the C9, just through HDMI 2.0b
    Most TV brands rely on this kinda of restricting of features, or not implementing them, just so they can market an extra reason for why you should buy this year's model rather than last year's, because panel & other important bits are slow to change. Indeed, if you look at the biggest difference between a C9 and a CX it's the lack of BFI @ 120 for the C9 even though it was something they had promised for it but then shelved and added it this year as a major feature. Exactly the kind of shenanigans I'm talking about.
