Discover the differences between HDMI 2.1 and HDMI 2.1b, including support for higher resolutions, Dynamic HDR, and Source-Based Tone Mapping. Learn how these advancements improve video and audio quality for immersive viewing
Both HDMI 2.1 and 2.1b support ultra-high resolutions, including 8K at 60Hz and 4K at 120Hz, with HDMI 2.1b adding 10K support for specialized uses
This allows for incredibly detailed and smooth video playback, enhancing visual experiences in both consumer and professional settings.
Both versions ensure optimal display settings for each frame, enhancing depth, detail, brightness, contrast, and color.
Dynamic HDR adjusts picture settings scene-by-scene or frame-by-frame, providing the best possible image quality.
Exclusive to HDMI 2.1b, SBTM allows HDR mapping by the source device, optimizing mixed HDR and SDR content.
SBTM lets the source device handle HDR tone mapping, improving the display of combined HDR and SDR content.
Required for both, supporting 48G bandwidth with low EMI emission, and backward compatibility with older HDMI versions.
This cable is designed to handle high data rates and reduce electromagnetic interference, ensuring reliable performance.
eARC in both versions supports the most advanced audio formats, ensuring high audio quality and compatibility with new devices.
eARC facilitates the use of high-bitrate audio formats, providing a superior audio experience.
Present in both, VRR reduces lag, stutter, and frame tearing, ensuring smoother gameplay.
VRR dynamically adjusts the refresh rate to match the frame rate, eliminating visual artifacts in games.
Both versions support ALLM, automatically setting the ideal latency for smooth and lag-free viewing.
ALLM enables the Screens to switch to a low latency mode, reducing input lag.
Supported by both, QFT reduces latency for smoother gaming and real-time VR experiences.
QFT decreases the time it takes for frames to be transmitted, enhancing the responsiveness of interactive content.
Both eliminate delays when switching frame rates, ensuring seamless transitions between different content types.
QMS prevents the screen from going black when changing between different video frame rates.
HDMI 2.1b extends support for higher resolutions up to 10K, beneficial for advanced AV and specialized applications.
HDMI 2.1b's 10K support caters to future-proofing for professional and commercial displays.
Both support Dynamic HDR, optimizing video display on a scene-by-scene or frame-by-frame basis.
Dynamic HDR ensures that every part of the video is shown with the best possible picture quality.
HDMI 2.1b is backward compatible with earlier HDMI versions, ensuring seamless integration with existing devices.
Backward compatibility means that newer HDMI versions can still connect and work with older HDMI devices.
HDMI 2.1b enables active HDMI cables to be powered directly from the HDMI connector, simplifying cable management.
This feature allows active cables to be powered by the HDMI port itself, eliminating the need for additional power sources.
