The next version of HDMI is all about increasing bandwidth to carry better video and audio, not small, incremental improvements. HDMI 2.2, unveiled at CES 2025 and officially released by the HDMI Forum in June of that year, increases the maximum bandwidth to 96Gbps, double that of HDMI 2.1, allowing more uncompressed video data to be moved between devices.
HDMI 2.2 can carry uncompressed 4K video at up to 240Hz, which currently requires Display Stream Compression. It can also reach 4K at 480Hz using 4:2:0 chroma subsampling, and handle uncompressed 8K RGB at 60Hz.
