HDMI 2.1 is compatible with 4K at 120Hz, 8K at 60Hz, and 10K resolutions for commercial A/V applications.

The format includes dynamic high dynamic range (HDR) support to help ensure improved video performance with improved depth, detail, brightness, contrast and wider color gamut capabilities on a scene-by-scene or frame-by-frame sequence.

Other highlights include:

  • Ultra High Speed HDMI Cable supports 48Gbps bandwidth for uncompressed HDMI 2.1 support, with low EMI emission and backwards compatibility with earlier HDMI specifications.
  • The format’s eARC is designed to simplify connectivity, while providing ease-of-use, and it helps to ensure compatibility between audio devices and upcoming HDMI 2.1 products.
  • Improved refresh rates for smoother images and more seamless transitions for gaming, movies and video content.
  • Quick Media Switching (QMS) for movies; this feature eliminates delays that result in blank screens before content is displayed.
  • Quick Frame Transport (QFT) reduces latency for an improved gaming experience.
  • Auto Low Latency Mode (ALLM) enables the correct latency setting to automatically set for smoother, lag-free uninterrupted viewing.
