The HDMI Forum, the organization responsible for developing the HDMI standard, will hold a press conference on January 6, 2025, on the sidelines of CES in Las Vegas which will begin the next day. This event, announced by the HDMI Licensing Forum, will be an opportunity to unveil the technical specifications of a new version of the standard, probably HDMI 2.2, and to present its implications for the industry.
The technical characteristics of this new version of HDMI are not yet known, but we can already speculate on the possible advances and new features that will be announced. Let us recall in passing that the most recent version of HDMI, stamped 2.1b and which dates from August 2023, already offers the possibility of displaying 4K definitions at 144 Hz, 8K at 30 Hz and even 10K at 30 Hz, all without compression thanks to its usable bandwidth of 42.6 Gbps (48 Gbps with control signals). Using DSC 1.2a compression (Display Stream Compression) even allows you to climb to 240 Hz in 4K, 120 Hz in 8K and 100 Hz in 10K.
HDMI 2.2: Speculations on bandwidth and definitions
The HDMI 2.2 will probably benefit from greater bandwidth, perhaps similar to the 80 Gbps of the DisplayPort 2.x standard, in order to support even higher definitions and/or higher refresh rates without compression. It is also likely that the new HDMI standard will improve DSC compression and add support for new technologies.
This new version of the standard will necessarily continue to support features added over time to HDMI, such as CEC (Consumer Electronics Control) which allows you to control the different elements of an audio/video set, HDCP anti-copy lock, the different variations of HDR, the optional Cable Power function, compressed audio formats such as Dolby TRueHD or DTS-HD Master Audio or the VRR (variable refresh rate). The increase in bandwidth could also make it possible in certain cases to do without DSC compression, particularly in HDR.
As always, the introduction of a new HDMI standard will more or less quickly have an impact on the entire technological ecosystem: manufacturers of televisions, monitors, graphics cards, video game consoles and video games. Other multimedia devices will gradually have to adapt their products to take advantage of HDMI 2.2. And of course, as always, consumers will have to purchase cables compatible with this new standard to take full advantage of its new features. Provided that these are really useful to you…
