HDMI 2.2 vs. 2.1: Key Differences for Gamers & Creators

Resolution and Refresh Rate Support

For gamers, higher refresh rates mean more fluid gameplay. HDMI 2.1 enabled 4K at 120Hz, reducing input lag and providing a more responsive gaming experience. However, with HDMI 2.2, those with 8K monitors can now enjoy a 120Hz refresh rate, which was previously unattainable.

Content creators also stand to gain. The ability to work with 16K resolution in real – time for video editing or graphic design is now possible with HDMI 2.2. HDMI 2.1, while great, falls short in this aspect as it maxes out at 8K resolution.

HDMI-Version	Max Resolution at Max Refresh
HDMI 2.1	8K@60Hz, 4K@120Hz
HDMI 2.2	16K@60Hz, 8K@120Hz

Audio – Visual Synchronization

HDMI 2.2 introduces the Latency Indication Protocol (LIP). This is a game – changer for both gamers and creators. In a multi – device setup, such as a gaming console connected to an AV receiver and then to a TV, LIP ensures that audio and video are perfectly synchronized. In contrast, HDMI 2.1 doesn’t have this specific protocol for latency indication, which could lead to minor audio – video sync issues in complex setups.

Cable Requirements

To fully utilize the capabilities of HDMI 2.1, Ultra High – Speed HDMI cables are required. These cables are designed to handle the 48 Gbps bandwidth. For HDMI 2.2, new Ultra96 cables are needed to support the 96 Gbps bandwidth. Although HDMI 2.2 cables are backward – compatible, connecting an HDMI 2.2 cable to a device with only HDMI 2.1 support will limit the performance to 48 Gbps.

Who Should Upgrade?

Gamer: If you have an 8K monitor or are planning to invest in one, and you want to take advantage of 120Hz refresh rates for the most immersive and responsive gaming experience, HDMI 2.2 is worth considering. For example, with the next – gen gaming consoles rumored to support 8K@120Hz, HDMI 2.2 will be essential.

Schöpfer: Those working with ultra – high – resolution content, like 16K video for film or large – scale graphic design projects, will benefit from the increased bandwidth of HDMI 2.2. It allows for real – time preview and editing without lag.

However, if you are content with 4K at 120Hz or lower resolutions, HDMI 2.1 will likely still meet your needs, and you may not need to upgrade just yet.

In conclusion, HDMI 2.2 is a significant upgrade over HDMI 2.1, but the decision to upgrade depends on your specific needs and the equipment you own or plan to purchase.
