HDMI 2.2 Approaches: First Devices Expected in 2027 with Bandwidth up to 96 Gbps

HDMI 2.2 takes a new step toward market launch. Rob Tobias, president and CEO of HDMI Licensing Administrator (HDMI LA), confirms that semiconductor manufacturers are already working on the first samples of chips based on the new standard, while certification and validation procedures are currently underway.

The roadmap anticipates the arrival of the first compatible products as early as next year, but to see devices fully capable of utilizing the maximum bandwidth of 96 Gbps, it may take until 2027. This timeline is reminiscent of what happened with HDMI 2.1, which was announced well in advance of its actual mass-market release.

The main novelty of HDMI 2.2 is the doubling of bandwidth compared to the current generation. The new standard indeed increases from 48 Gbps to 96 Gbps due to advancements in Fixed Rate Link (FRL) technology, introducing a new transmission mode that significantly broadens data transfer capacity.

The bandwidth increase allows for managing much more demanding video streams without necessarily resorting to DSC (Display Stream Compression). Supported configurations include uncompressed 4K signals up to 240 Hz and 8K up to 120 Hz, while using compression techniques theoretically allows pushing further into scenarios like 8K at 240 Hz or refresh rates exceeding 1000 Hz at lower resolutions.

These new capabilities are primarily designed for high-end gaming monitors, professional applications related to video production, virtual reality systems, and future ultra-high-resolution home theater platforms. However, at least in the short term, many users may not perceive tangible benefits, considering that a large portion of currently available content and devices does not require bandwidth exceeding that offered by HDMI 2.1.

An important aspect concerns the practical implementation of the standard. As previously happened, the presence of the HDMI 2.2 label will not automatically ensure support for maximum bandwidth. Some products may indeed stop at 64 or 80 Gbps, while only complete implementations will reach 96 Gbps. Therefore, it will be essential to carefully check the technical specifications of individual devices.

Alongside the increase in bandwidth, HDMI 2.2 also introduces new functionalities dedicated to home entertainment. Among these stands out the Latency Indication Protocol (LIP), a technology designed to improve synchronization between audio and video in systems involving multiple components, such as televisions, soundbars, and AV receivers, reducing potential audio-video sync issues.

Additionally, the Ultra96 certification program has been announced, which will identify cables capable of supporting the full transmission capacity allowed by the new standard. Only using certified Ultra96 cables will it be possible to utilize all 96 Gbps provided by complete HDMI 2.2 implementations.

From a technical perspective, the adoption of the new generation of FRL should also help simplify the standard's integration and address some compatibility issues that arose in the early years of HDMI 2.1 deployment. It remains to be seen how quickly the hardware ecosystem will adapt to the novelties, but the path toward the next generation of video connections appears to be firmly underway.
