What is HDMI 2.2? Should I upgrade?

The next version of HDMI, version 2.2, has officially launched after the HDMI forum announced the new standard at CES 2025. HDMI 2.2 promises many exciting features for home entertainment and many people are looking forward to it. Upgrade to new version.

What is HDMI 2.2?

HDMI 2.2 is the latest version of the High Definition Multimedia Interface (HDMI) standard. If you're unfamiliar with HDMI, it is a digital interface for transmitting audio and video signals between devices. HDMI 2.2 is the next version of HDMI 2.1, announced in January 2017. (The following is a comparison between HDMI 2.1, 2.0 and 1.4 for your reference).

As such, HDMI 2.2 unlocks new capabilities, including support for 12K (12,288 x 6,480) and 16K (15360 x 8640) resolutions and higher refresh rates for those resolutions currently supported by HDMI 2.1. This makes the new standard an important factor in the next iteration of high-resolution displays, gaming and multimedia setups.

Increased bandwidth will also help power data-intensive applications such as augmented reality, virtual reality and mixed reality. This standard uses a special Ultra96 cable that takes full advantage of additional features, a new option for different HDMI cables that you should know about.

Why upgrade to HDMI 2.2?

By doubling bandwidth from 48Gbps to 96Gbps, HDMI 2.2 unlocks higher display resolutions and refresh rates. With additional bandwidth, this standard can now support 12K and 16K display resolutions. To understand better, HDMI 2.1 can only support resolutions up to 10K.

Of course, these higher resolutions are aimed at commercial use cases (like digital signage). The interesting upgrade for regular consumers is a new specification that improves the maximum refresh rate across different resolutions. It supports 4K at 480Hz, 8K at 240Hz, and 10K at 120Hz. HDMI 2.1 is crucial for gaming, so for gamers, the successor means an even better experience on both PC and console.

Another worthwhile upgrade when moving to HDMI 2.2 is the new Latency Indication Protocol (LIP), which, according to HDMI Forum, will improve audio and video synchronization, especially when using an audio receiver or soundbar. So if you're still having sync issues even though eArc is out with HDMI 2.1, hopefully the next version will fix it.

However, one downside to HDMI 2.2 is the requirement for a new cable. HDMI 2.2 will use the same connector but requires the new HDMI Ultra96 cable to support the higher 96Gbps bandwidth. That means when you upgrade, it's not just the device; The cable also needs to be changed.

HDMI 2.2 has officially launched, but like its predecessor, it will take some time before it becomes widespread on many devices. All the different players will need to catch up for this to happen. It was worth the wait, though, and many people are eager to upgrade as manufacturers start adding HDMI 2.2 support to various hardware devices.
