High-Definition Multimedia Interface Specification 2.1 feature highlights include:

★Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 8K are also supported for commercial AV, and industrial and specialty usages.

★Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.

★The Ultra High Speed High-Definition Multimedia Interface Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the High-Definition Multimedia Interface Specification and can be used with existing High-Definition Multimedia Interface devices.

★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 High-Definition Multimedia Interface 2.1 products.

Enhanced refresh rate 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.

Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.

Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.

★Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.
