As you can see, the HDMI Forum mentions higher bandwidth which will require new HDMI cables. For the moment, no hardware integrating HDMI 2.2 has yet been announced, but there is no doubt that the first products to integrate it will be unveiled at CES, starting with the nVidia and AMD conferences, they are also rumored that RTX 5000 graphics cards would be compatible with HDMI 2.2.
The increase in HDMI bandwidth, currently limited to 48 Gbps, should notably make it possible to ensure the transmission of streams up to 8K at 120 Hz with or without compression, or even to go up to 240 Hz without compression. in 4K Ultra HD. As a reminder, the HDMI 2.1 standard allows 8K streams to be displayed at 30 Hz without compression, and up to 60 Hz with DSC — Display Stream Compression. For now, these are just speculations, as no technical details have yet been revealed. Despite everything, we imagine that the HDMI Forum wishes to show itself at the level of VESA, the organization behind the DisplayPort standard, a connection which has, with its latest standard, a bandwidth of 80 Gbps.
