HDMI 2.2 has been revealed, and it promises 96 Gbps of bandwidth
HDMI shoots past DisplayPort with their new 96 Gbps standard
Today, the HDMI Forum has officially revealed HDMI 2.2, the latest version of their HDMI specification. With HDMI 2.2, the standard’s available bandwidth has been doubled to 96 Gbps. This shoots the HDMI standard past DisplayPort 2.1b, which has a maximum bandwidth of 80 Gbps.
With this additional bandwidth, HDMI 2.2 will support higher resolutions and refresh rates than today’s HDMI 2.1 standard. The new specification for HDMI 2.2 will be released in H1 2025. Currently, it is unknown if the standard will be supported by any soon-to-be-released graphics cards.
Higher resolutions and refresh rates will be supported and more high-quality options will be provided. Faster 96 Gbps bandwidth improves demanding data-intensive, immersive and virtual applications such as AR/VR/MR, spatial reality and light field displays as well as various commercial applications such as large scale digital signage, medical imaging and machine vision.
Alongside the release of HDMI 2.2 will come the release of new 96 Gbps “ULTRA96” HDMI cables. These cables are certified to handle the high bandwidth of HDMI’s newest standard and support all of the standard’s features.
Included with HDMI 2.2 is a new Latency Indication Protocol (LIP) that will improve audio/video synchronisation for supported devices. This will be very useful for “multiple-hop” system configurations, like those that use an audio/video receiver.
Currently, it is unknown when we will see HDMI 2.2 devices come to market. It is possible that it may not be supported by PC GPUs until the release of future product generations (not those that will be revealed at CES). However, it is possible that HDMI has worked with AMD and/or Nvidia to add this tech to their new 2025 GPUs.
You can join the discussion on HDMI 2.2 on the OC3D Forums.
