HDMI 2.2 vs 2.1 Comparison: Is 96Gbps Worth the Upgrade

HDMI 2.2 was officially released in June 2025, bringing major upgrades like 96Gbps bandwidth, improved sync protocols, and Ultra96-certified cables. But how does it compare to HDMI 2.1, and should you upgrade? Here's what you need to know.

Part 1: What is HDMI 2.2? Differences between HDMI 2.2 VS 2.1

HDMI 2.2 is the newest version of the HDMI standard, officially released in June 2025. It was developed to meet the increasing demands of ultra-high-resolution displays, faster refresh rates, and smoother A/V performance. One of its biggest highlights is support for up to 96Gbps bandwidth—nearly double that of HDMI 2.1.

This boost allows for advanced formats like 8K at 240Hz, 12K at 120Hz, and even 16K at 60Hz when using DSC (Display Stream Compression). HDMI 2.2 also brings improved audio-video sync, more reliable handshakes between devices, and a new Ultra96 cable certification to ensure consistent performance.

In short, HDMI 2.2 is built for the future of gaming, content creation, and high-end home entertainment.

HDMI 2.2 vs HDMI 2.1: Key Differences

Part 2: Should I Upgrade to HDMI 2.2?

When it comes to HDMI 2.2, the cables will be ready before most of the devices. Ultra96-certified HDMI 2.2 cables, which support up to 96Gbps bandwidth, are expected to hit the market by the end of the year or next year. These cables are designed to handle the demands of next-gen gaming, 8K+ displays, and high refresh rates.

However, just like with HDMI 2.1, display upgrades won’t happen overnight. Most TVs, monitors, and GPUs on the market today won’t fully support HDMI 2.2. It may take until 2026 or even 2027 before these devices become widely available and affordable.

So should you upgrade your cables now? If you're building a future-proof setup—or plan to upgrade your display or graphics card soon—it makes sense to invest in HDMI 2.2-ready cables. They're backward compatible and will ensure you're ready when new hardware arrives. But if your current setup works fine and you're not planning big changes, there's no rush.

Part 3: What is Ultra96 certification?

Ultra96 is the new official cable certification introduced alongside HDMI 2.2. It’s designed to guarantee that a cable can reliably support the full 96Gbps bandwidth that HDMI 2.2 enables. Not all cables will qualify—this certification is meant for a new generation of high-performance HDMI cables built for future video and gaming demands.

Ultra96 certification introduces three bandwidth tiers: 64Gbps, 80Gbps, and 96Gbps. Each tier targets different video standards and refresh rates. For example, 64Gbps cables can handle 8K@120Hz, while 96Gbps cables support up to 8K@240Hz or 12K@120Hz using Display Stream Compression. This tiered approach allows users to choose cables based on their exact needs and budgets.

Ultra96 certification marks a shift in HDMI cable standards, reflecting growing demand for ultra-high resolution and refresh rates. As 8K and beyond become more common, Ultra96 cables will be essential for gamers, creators, and home theater enthusiasts. Expect to see more specialized cable brands like Silkland launching Ultra96-certified cables throughout 2025 and beyond.

Part 4: Is HDMI 2.2 backwards compatible?

Sure! HDMI 2.2 is fully backwards compatible with previous HDMI versions, including HDMI 2.1, 2.0, and even earlier.

This means you can use an HDMI 2.2 cable with your current TV, monitor, or gaming console without issues. The cable and device will automatically negotiate the highest supported standard. So if your display only supports HDMI 2.1 or 2.0, it will still work perfectly with an HDMI 2.2 cable.

However, while compatibility is guaranteed, you won’t get the full benefits of HDMI 2.2 features unless all devices in the chain support the new standard. For example, to enjoy 8K at 240Hz or the improved audio-video sync, your TV, graphics card, and cable must all be HDMI 2.2 certified.

Frequently Asked Questions - HDMI 2.2

Q1: Is HDMI 2.2 backward compatible with 2.1?

Yes, HDMI 2.2 is fully backward compatible with HDMI 2.1 and older versions. You can use HDMI 2.2 cables and devices with HDMI 2.1 gear without issues, but the connection will operate at the lower standard’s capabilities.

Q2: Can HDMI 2.1 cables support HDMI 2.2?

HDMI 2.1 cables may physically connect and work with HDMI 2.2 devices, but they don’t guarantee the full 96Gbps bandwidth or advanced features of HDMI 2.2. For best results, use Ultra96-certified HDMI 2.2 cables.

Q3: Do I need a new TV for HDMI 2.2?

Yes, to take full advantage of HDMI 2.2 features like higher resolutions and refresh rates, your TV or display must support HDMI 2.2. Older TVs won’t unlock these new capabilities even if you use HDMI 2.2 cables. But it may be a while before displays capable of supporting HDMI 2.2 are available.

Q4: What cable supports 8K 240Hz?

To reliably run 8K at 240Hz, you’ll need a certified Ultra96 HDMI 2.2 cable with 96Gbps bandwidth. These cables are designed specifically for high-bandwidth video and gaming.

Alternatively, if your device supports DisplayPort 2.1 and enables DSC (Display Stream Compression), you can use high-performance cables like the Silkland DP80 cable to achieve 8K 240Hz over DP.

Q5: Do I need a new cable for HDMI 2.2?

If you want to fully utilize HDMI 2.2’s features and higher bandwidth, yes, you need to upgrade to an Ultra96-certified HDMI 2.2 cable. Older cables may not support the increased data rates required.

Conclusion

HDMI 2.2 is built for the next generation of displays, gaming, and content. Whether you're upgrading now or planning ahead, understanding Ultra96 cables and compatibility will help you make smarter choices and get the most from your setup.
