The HDMI Forum has formally announced the launch of version 2.2 of the HDMI specification, which adds support for video resolutions reaching 16K at 60Hz and boosts maximum bandwidth to 96Gbps. This revision also introduces a new cable category known as Ultra96.
### The Technical Details
The HDMI 2.2 specification now accommodates video resolutions of up to 16K at 60Hz and 12K at 120Hz. For uncompressed formats with full 4:4:4 chroma and 10-bit and 12-bit color depth, it is capable of supporting 4K at 240Hz and 8K at 60Hz. This functionality is made achievable through the enhanced 96Gbps bandwidth and next-generation FRL signaling, which improves reliability in high-bandwidth conditions.
Chandlee Harrell, president of the HDMI Forum, remarked, “The HDMI Forum is excited to unveil the new HDMI 2.2 Specification to enable enhanced performance capabilities and features for innovative and immersive new solutions and products. (…) Furthermore, the introduction of the new Ultra96 feature name will assist consumers and end-users in confirming that their product’s maximum bandwidth is accommodated.”
### What is Ultra96?
Ultra96 is designed as the subsequent evolution beyond the current “Ultra High Speed” cables, which support a maximum of 48Gbps. The HDMI Forum clarifies that “Ultra96” is a feature designation that manufacturers are urged to adopt to signify a product’s capability to handle up to 64Gbps, 80Gbps, or 96Gbps bandwidth in accordance with the HDMI 2.2 Specification. The new Ultra96 HDMI Cable accommodates up to 96Gbps and all HDMI 2.2 functionalities.
Ultra96-certified HDMI cables and compatible devices are anticipated to begin arriving later this year. Additionally, HDMI 2.2 rolls out the Latency Indication Protocol (LIP), aimed at enhancing audio/video synchronization across systems where signals traverse multiple devices before reaching the ultimate display.
Although 16K displays are not yet commonly accessible, and the majority of content currently maxes out at 4K or 8K, HDMI 2.2 is oriented towards future-proofing, ensuring manufacturers have a reliable standard as hardware and media evolve in terms of frame rates and resolutions.
