HDMI 2.2 Standard to be Announced at CES with Higher Bandwidth and a New Cable

A press invite sent out ahead of the CES 2025 event in Las Vegas has teased the announcement of a new, next generation “HDMI 2.2” standard which will offer higher bandwidths and a new cable spec. Their press event will take place on 6 January 2025, one day before the main CES event kicks off. Very little official information is provided about the new standard at this stage, but the press invite says:

“The HDMI Forum will be announcing a new HDMI Specification release. The new specification, with next-gen HDMI Technology and higher bandwidth, enables a wide range of higher resolutions and refresh rates and will be supported with a new HDMI Cable. New technology enables higher quality options now and in the future”

What to expect from HDMI 2.2 specs

Higher bandwidths are specifically mentioned in the press release, but what that will mean is yet to be unveiled. Existing HDMI 2.1 connections can provide up to 48Gbps of total bandwidth with a data rate of 41.89 Gbps. This has been surpassed in recent times by the competing DisplayPort connection, which can now support up to 80Gbps maximum in the DisplayPort 2.1 standard.

There seems to be an ongoing competition between HDMI and DP, and so it’s likely that the new bandwidths could exceed what’s possible from DP 2.1 at the moment. We’ll know more from the CES announcement in a few weeks. A new cable will also be needed to support any higher bandwidths it is expected, although details on what impact this will have, how they will be certified, what they will be called etc is still to be confirmed.

What does this mean for DP 2.1?

It’s probably only a matter of time before VESA announce some nominal update to the DP 2.1 spec to allow them to start calling that DisplayPort 2.2 instead. They did the same thing with what was originally going to be called DisplayPort 2.0 prior to much real adoption of that new connection, renaming it to DisplayPort 2.1 after some spec updates to keep up with the naming convention of HDMI 2.1. We’d expect to see similar once HDMI 2.2 is more formal and starts to be utilised, so that DP 2.1 doesn’t sound like it’s lagging behind HDMI 2.2.

Will we see HDMI 2.2 included in new graphics cards at CES?

With NVIDIA expected to announce their new RTX 5000 next gen graphics cards at CES, we’ve seen this suggestion on various websites but frankly we think this is incredibly wishful thinking and is extremely unlikely to happen. The HDMI forum are only making the initial announcement of the spec at CES, and if HDMI 2.1 is anything to go by it will take nearly a year before it even gets released properly. From there, the adoption in to PC graphics cards can take several YEARS before they are released to market. Monitors using that new connection would be even later.

If you look back at HDMI 2.1 that was announced by the HDMI Forum on January 4, 2017 and was released on November 28, 2017. The first NVIDIA graphics cards to offer this connection were not launched until September 2020 almost 3 years later. Based on this we would suggest there is next to zero chance that we’d seen this new HDMI 2.2 connection and standard included on the new NVIDIA RTX 5000 series that are expected to be announced at CES.

More information coming soon

Much more information on the new spec and standard coming soon from CES so stay tuned.
