HDMI has been the leading standard for transmitting high-quality audio and video signals for years. With the announcement of HDMI 2.2, the question arises: How does this new standard differ from HDMI 2.1, and is an upgrade worth it?
In this article, we explain the key differences between HDMI 2.2 and HDMI 2.1, delve into the new technical specifications, and clarify the advantages of the new technology.
HDMI 2.2 vs. HDMI 2.1: The Technical Differences
The most significant difference between HDMI 2.1 and HDMI 2.2 lies in the maximum bandwidth. While HDMI 2.1 already marked a significant improvement over HDMI 2.0, HDMI 2.2 sets new standards.
Data Transfer Rate and Bandwidth
- HDMI 2.1: Supports a maximum bandwidth of 48 Gbit/s
- HDMI 2.2: Doubles the bandwidth to 96 Gbit/s
This increased bandwidth means that more data can be transmitted in less time, which is particularly beneficial for high-resolution content with high refresh rates.
Supported Resolutions and Refresh Rates
- HDMI 2.1: 4K at 120 Hz, 8K at 60 Hz
- HDMI 2.2: 4K up to 480 Hz, 8K at 240 Hz, 12K at 120 Hz
Improved Audio Synchronization
HDMI 2.2 introduces the Latency Indication Protocol, which synchronizes video and audio signals more precisely. This is particularly important for home theater systems and gaming setups.
HDR and Color Support
- HDMI 2.1: Already offers extensive HDR support for Dolby Vision, HDR10+, and HLG.
- HDMI 2.2: Enhances color reproduction through optimized HDR algorithms and more stable transmission.
Do You Need New Cables for HDMI 2.2?
With HDMI 2.2, a new type of cable is introduced: the "Ultra96" HDMI cable. While HDMI 2.1 relied on Ultra High Speed cables, HDMI 2.2 requires the new cables to fully utilize the 96 Gbit/s bandwidth. Older cables can still be used but will be limited in performance.
Availability of HDMI 2.2 Devices
While HDMI 2.1 has been available in many TVs, monitors, and AV receivers since 2020, HDMI 2.2 is still in the planning phase. The first HDMI 2.2 devices are expected to hit the market in 2026, starting with high-end models. Compatible cables are expected to be available by late 2025, ensuring that the new technology can be fully utilized as soon as the first devices become available.
Frequently Asked Questions About HDMI 2.2 vs. HDMI 2.1
Which HDMI Cable Is Necessary for 120 Hz?
For 120 Hz at 4K resolution, a HDMI 2.1 Ultra High Speed cable is sufficient. HDMI 2.2 cables will only become relevant when devices supporting 240 Hz or higher resolutions with high refresh rates hit the market.
Will Switching to HDMI 2.2 Be Necessary?
If you're using 4K at 120 Hz or 8K at 60 Hz, HDMI 2.1 is more than sufficient. HDMI 2.2 is mainly worthwhile for users who want to benefit from very high refresh rates and resolutions. Gamers who want to play in 4K at 480 Hz or even higher frame rates will benefit from the improved bandwidth. Home theater enthusiasts who want to experience the full quality of 8K or even 12K content will also be well-prepared for future developments with HDMI 2.2.
Is HDMI 2.2 or HDMI 2.1 Important for the PS5?
The PS5 supports HDMI 2.1 and can thus display content in 4K at 120 Hz, provided a compatible TV or monitor is available. However, the console does not currently utilize any of the additional features that a potential HDMI 2.2 upgrade could offer. Therefore, switching to HDMI 2.2 brings no benefits for PS5 usage. To get the most out of the PS5, you should use a certified HDMI 2.1 cable and a compatible display with VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) to ensure an optimal gaming experience with smooth visuals and low latency.
Conclusion
HDMI 2.2 introduces several significant improvements in terms of bandwidth, resolutions, and synchronization, but for now, it remains a technology for future applications. HDMI 2.1 is currently more than sufficient for gamers and home theater users. However, those looking to future-proof their setup should keep an eye on HDMI 2.2 as soon as compatible devices become available.
