Forward-looking: The next version of HDMI is mainly about pushing bandwidth higher to carry better video and audio, not small, incremental tweaks. HDMI 2.2, teased at CES 2025 and formally released by the HDMI Forum in June of that year, raises maximum bandwidth to 96Gbps, twice that of HDMI 2.1, allowing more uncompressed video data to move between devices.
HDMI 2.2 can carry uncompressed 4K video at up to 240Hz, something that currently requires Display Stream Compression (which as we've shown however, is not a big limitation). It can also reach 4K at 480Hz using 4:2:0 chroma subsampling, and handle uncompressed RGB 8K at 60Hz.
The added bandwidth cuts down on the compression and other tricks current hardware has had to rely on to push high frame rates. For gamers, that extra...
