    8k is 33 177 600 pixels.
    On 32-bit color scheme that's 1 061 683 200 bits for one frame.
    Which is 127 401 984 000 bit/s for 120Hz, aka 127Gbit/s. That's a lot of data.

    Thought tv panels was 8 or 10 bit at most?

    8 or 10 bit per channel, so R+G+B at 10bit of depth = 30 bit. Dunno whether it needs the extra bits for anything, but if it doesn't the bandwidth is still a tad over 111Gbit/s, which is monstrous.

    No idea.. would make it a bit more feasible, though.

    Edit: Just realized after posting this - 8bit scale is way too small.

    Just wondered with hdmi 2.1 bandwidth reaching 48Gbps maximum, how it's able do 8k 120 hz? compression?

    yeah it is.

    the article stated it was Dolby compliant so that's a 10 bit processor.
    they would need FRC @8k, but not 4k.

    Display Port 2.0? Maybe? I mean this thing just sounds crazy, but like you're saying though at what level? That's a lot of data for sure.

    Mmm, my next TV will likely have this unless there is good competition by then :)

    *Usually not 32-bit color.
    *Compression.
    *In most situations, every pixel in every frame isn't isn't being changed.
