HDMI 2.2 marks a significant advancement in video transmission technology, primarily due to its support for ultra-high resolutions and increased bandwidth. HDMI 2.2 doubles the maximum data transfer rate from the previous standard's 48 Gbps to an impressive 96 Gbps, enabled by the new "Ultra96" cables . This enhancement facilitates unprecedented display capabilities, including native support for 16K resolution at 60 Hz and higher refresh rates for lower resolutions, such as 4K at up to 240 Hz with enhanced color depth.
 HDMI 2.2 specification to manufacturers today. Although there is no definitive timeline for how long it will take hardware makers to adopt the new specification, the first Ultra96 HDMI Cables, with bandwidth capabilities boosted to up to 96Gbps, could be available later this year.
HDMI 2.1 and the current Ultra High Speed HDMI cables have a maximum bandwidth of 48Gbps which supports resolutions up to 10K and refresh rates up to 120Hz with 4K content. HDMI 2.2 and the new Ultra96 cables will enable even higher resolutions and refresh rates including 4K at 480Hz, 8K at 240Hz, 10K at 120Hz, and even 16K at 60Hz. It will also handle uncompressed video formats with 10-bit and 12-bit color at 8K at 60Hz and 4K at 240Hz.
This new bandwidth unlocks 16K resolution support at 60 Hz and 12K at 120 Hz, but with chroma subsampling. That being said, you can expect 4K 240 Hz at up to 12-bit color depth without any compression. DisplayPort 2.1b UHBR 20 was the first to do this with some monitors already available on the market, but that standard is limited to only 80 GB/s and HDMI 2.2 edges it by just a bit, which allows for even uncompressed 8K at 60 Hz.
Also new in HDMI 2.2 is the Latency Indication Protocol (LIP), aimed at improving audio/video sync across systems where the signal hops through more than one device before reaching the final display.
Of course, 16K displays aren’t exactly lining store shelves just yet. And while most content currently tops out at 4K or maybe 8K, HDMI 2.2 is more about long-term support and ensuring manufacturers have a standard at hand, as hardware and media continue pushing frame rates and resolutions upward.
Besides increased performance metrics, HDMI 2.2 maintains backward compatibility with earlier standards, ensuring seamless integration into existing setups while paving the way for future hardware upgrades. The inclusion of the Latency Indication Protocol (LIP) further refines user experience by improving audio-video synchronization—a critical factor in media consumption and gaming applications . Overall, HDMI 2.2 represents a pivotal step forward in audiovisual technology that aligns with evolving consumer demands and emerging device capabilities.
