HDMI 2.2 vs. HDMI 2.1: What You Need to Know
HDMI 2.2 is set to bring advancements in technology, particularly for augmented and virtual reality applications. However, existing users of HDMI 2.1 need not worry about immediate upgrades for their home entertainment systems. Here are the key details about the newer specification and its implications.
Overview of HDMI 2.1
Introduced in 2017, HDMI 2.1 significantly increased bandwidth capacity from 18 Gbps to 48 Gbps, allowing for higher video resolutions and refresh rates, including 4K at 120 Hz and 8K at 60 Hz. It supports advanced features beneficial for gaming such as variable refresh rate (VRR) and low-latency mode. Other enhancements include dynamic HDR for optimised picture quality and HDMI eARC for better audio transmission.
Key Innovations in HDMI 2.2
HDMI 2.2 doubles the bandwidth capabilities to 96 Gbps, targeting commercial use and advanced consumer technologies. It features enhancements like the Latency Indication Protocol (LIP) that aids in audio and video synchronisation, making it especially useful for AR/VR and medical imaging applications.
What Users Need to Know
- HDMI 2.1 remains highly capable for most users, covering a wide range of current A/V needs.
