The HDMI Forum is launching the HDMI 2.2 specification, first revealed at CES 2025. This new standard, along with Ultra96 HDMI cables (up to 96Gbps bandwidth), promises enhanced resolution and refresh rates, potentially enabling 4K at 480Hz, 8K at 240Hz, 10K at 120Hz, and even 16K at 60Hz. It will support uncompressed video formats with 10-bit and 12-bit color. While 16K content is unlikely to become mainstream soon, HDMI 2.2 aims to future-proof the standard. The "Ultra96" naming will provide clarity in cable selection, addressing the confusion of current designations. Additionally, HDMI 2.2 introduces the Latency Indication Protocol (LIP), building upon HDMI 2.1's synchronization improvements, crucial for setups involving soundbars and AV receivers.

A Hacker News thread discusses the future of display technology, sparked by the announcement of HDMI 2.2 supporting 16K video at 60Hz. Users debate the limitations of current standards like DisplayPort 1.4 and HDMI 2.1, particularly regarding bandwidth for high resolutions and refresh rates. One user details their experience with a 6K monitor, highlighting the need for compression even with Thunderbolt 4, and the advantage of HDMI 2.1's higher bandwidth. The conversation also touches on monitor selection, with some preferring DisplayPort for its PC-centric focus and others lamenting the slow adoption of DisplayPort 2.0. Alternative standards like GPMI are mentioned. Users express desires for specific display features like 5K resolution at 120Hz with HDR, and the frustration of manufacturers prioritizing high refresh rates over high-resolution HiDPI widescreen displays. The lack of open-source HDMI 2.1 drivers on Linux is also criticized. The discussion touches on the consumer adoption of such high fidelity with many relying on compressed streaming services.

After first announcing it at CES 2025, the HDMI Forum is finally releasing the new 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.

Given how difficult it still is to find native 8K content, don’t expect cable providers or console makers to offer 16K anytime soon. HDMI 2.1 has been around since 2017 and hardware makers still don’t take full advantage of the spec, so the increased bandwidth and resolutions of 2.2 should help future-proof the HDMI specification for years to come.

The HDMI Forum is also hoping that the new specification will make it easier for consumers to know what cable they need to be using. HDMI cables are currently differentiated with names including Standard, High Speed, Premium High Speed, and Ultra High Speed, which doesn’t provide any specifics on their capabilities. With HDMI 2.2, the Ultra96 name will make it clear that a cable supports the new specification and bandwidths up to 96Gbps.

HDMI 2.2 will also include the new Latency Indication Protocol (LIP), which was also announced last January. The feature is designed to build on audio and video synchronization improvements introduced with HDMI 2.1, particularly for setups where signals are bouncing through a soundbar or an AV receiver before reaching a TV or projector.
