- The specification also includes a new Ultra96 HDMI cable that supports 96Gbps bandwidth and enables all new features.
Most people know HDMI as the cable standard used when you need to connect something to your TV. HDMI has made life so much simpler by saving us from the mess of multiple audio and video cables required to connect your source devices to the display and even enabling features like HDMI ARC. However, as source devices become more powerful, HDMI must keep up, and this is where the new HDMI 2.2 specification comes into play.
HDMI 2.2 future-proofs the standard by introducing a higher bandwidth of 96Gbps and a new generation of HDMI Fixed Rate Link technology. This enables multiple distribution platforms, while providing better quality options for content producers such as TV, film and game studios now and in the future.
The faster 96Gbps bandwidth with HDMI 2.2 improves data-intensive, immersive and virtual applications such as AR/VR/MR, spatial reality, light field displays and a variety of commercial applications such as large-scale digital signage, medical imaging and other commercial applications. car vision. Although technical details were not immediately available, the specification also includes support for higher resolutions and refresh rates. For reference, HDMI 2.1 supports 48Gbps bandwidth, variable refresh rates up to 120Hz, and resolution up to 10240 x 4320 with Display Stream Compression.
In addition, HDMI 2.2 also includes a new Latency Indication Protocol to improve audio and video synchronization, especially for multi-hop system configurations such as those with an audio-video receiver or soundbar.
The specification also includes a new Ultra96 HDMI cable that supports 96Gbps bandwidth and enables all HDMI 2.2 specification features. HDMI Forum Inc. has also made it part of the HDMI Cable Certification Program, requiring each model length to be tested and certified to display the certification label. The silver lining is that the shape of the port has not changed, so backwards compatibility is maintained for the specification.
The new HDMI 2.2 specification will be available to all HDMI 2.x adopters and will be notified when it is released in 2025. You can expect consumer devices to support this technology later in the year.
