Recently, The HDMI Forum released the new HDMI 2.1 specification where it supports higher resolution and refreshes rates- 4K @ 120 Hz and 8 @ 60 Hz. It also could support 10K at a much lower refresh rate as the new specification’s bandwidth is increased up to 48 Gbps. The cables which support the new specification will be called as ‘Ultra High-Speed HDMI Cable’.Because of the significantly increased bandwidth, the new cable is enabled to provide uncompressed 8K content with HDR. It also has a very low EMI which would typically disrupt wireless devices. This is great for system, component and device manufacturers as it would enable to provide high-performance hardware to its customers. As you would expect, the HDMI 2.1 has backward compatibility with the previous versions. HDMI specifications are used by multiple devices from computers to mobile devices and even digital cameras. The 2.1 specification is available to all HDMI 2.1 adopters.They will need to run a compliant test for the HDMI 2.1 certification.
It is also very interesting specification which assures to eliminate or reduce stuttering, lag and screen tearing. The ‘Quick Frame Transport’ feature is said to provide ‘smoother no-lag gaming and real-world interactive virtual reality’. The new Variable Refresh Rate (VRR) is made to provide that fluid gameplay experience. it does so by syncing the source and display with constantly changing refresh rates on a frame-to-frame basis. Because of this, frames are transmitted and displayed as soon as its rendered without any obstacles.
There are some improvements for video performance as its ‘Quick Media Switching’ eliminates the delay between the device and the display which results in a blank screen before the content is played.
The above images show the differences between the resolution and its benefits.
The rest of the HDMI 2.1 features are as follows:
- 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 10K 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 HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backward compatible with earlier versions of the HDMI Specification and can be used with existing HDMI 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 HDMI 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.
