HDMI 2.2支持12K 120Hz和16K 60Hz显示，还支持4K 240Hz和8K 60Hz的4:4:4格式，具备完整的10位和12位色深。
HDMI® 2.2 Specification
The HDMI 2.2 Specification is the most recent update of the HDMI Specification and delivers enhanced options for the vast HDMI ecosystem with more advanced solutions to create, distribute and experience the best end-user outcome. Higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology provide optimal audio and video for a wide range of device applications. An end-user can be assured that their displays support a native video format in the best way possible and can deliver a seamless and reliable experience.
Higher resolutions and refresh rates will be supported including up to 12K@120 and 16K@60. Additionally, more high-quality options will be supported including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color
HDMI 2.2 Specification feature highlights include:
- Up to 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology provide optimal audio and video for a wide range of device applications. Supported resolutions include 4K240 and 8K60, both uncompressed and with full chroma and 10/12-bit color. Also included is support for 10K, 12K and 16K resolutions.
- The new Ultra96 HDMI Cable supports up to 96Gbps bandwidth and is the only cable that supports all HDMI 2.2 Specification applications. It has very low EMI emission, can be used with existing HDMI devices and is part of the official Ultra Cable Certification Program.
- “Ultra96” is a feature name that manufacturers are encouraged to use to indicate a product supports a maximum of 64Gbps, 80Gbps or 96Gbps bandwidth in compliance with the HDMI 2.2 Specification, and require the Ultra96 HDMI® Cable to ensure a product’s maximum bandwidth is properly supported.
- The Ultra High Speed HDMI Cable was introduced in the HDMI 2.1 Specification and entered the market in 2020. It is applicable for system configurations supporting up to 48Gbps maximum bandwidth.
- Latency Indication Protocol (LIP) is an advancement over existing A/V sync methods for improving audio and video synchronization, especially for multiple-hop system configurations such as those with an audio video receiver or soundbar.
- eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.2 products.
- Enhanced gaming features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include:
- Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
- Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.
- Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
- Quick Media Switching (QMS) for movies and video eliminates the delay that often occurs when a device changes from one HDMI frame rate to another.
- HDMI Cable Power enables active HDMI Cables to be powered directly from the HDMI Connector, without attaching a separate power cable. This makes attaching and using active HDMI Cables as easy as using passive, wired HDMI Cables.
HDMI 2.2 Specification is backward compatible with earlier versions of the Specification and is available to all HDMI 2.1 Adopters.
