    Ya some morons will fall into the 120hz tv for the cable setup but you seem to only cater to those morons. What about the people who bought 120hz tvs to use with 120hz sources. and before you go all cnet on my ass and say theres no such thing I got 2 letters for you. PC

    Hdmi 1.4b supports the 120Hz 1080p throughput only for 3D processing, which it does by cloning the data packet for concurrent output to the display device. For 2D viewing – which is what almost all gamers mean when they want “120Hz” – HDMI 1.4b is stuck at just 60Hz for 1080p.

    For HDMI 2.0, 1080p120 falls well within the 600MHz pixel clock and 18Gbps throughput cap (even accounting for 8b/10b encoding). It is possible for 1080p to be supported at 120Hz on HDMI 2.0; unfortunately, very few solutions on-market are capable of actually utilizing this potential. Most monitors selling with HDMI 2.0, like the ASUS PB287Q, are 4K displays that cap-out at 60Hz. This is because HDMI is ultimately a consumer interface that’s targeted at TVs
