Hdmi2.1 specification overview
The latest HDMI specifications support a range of higher video resolutions, refresh rates including 8k60 and 4k120, and resolutions up to 10K. At the same time, it supports dynamic HDR format and increases the bandwidth capacity to 48g HDMI.
The new ultra high speed HDMI cable supports 48Gbps bandwidth. The cable ensures high bandwidth independence, including uncompressed 8K video that supports HDR. Ultra low EMI (electromagnetic interference) can reduce the interference to nearby wireless equipment. The cable is backward compatible and can also be used in existing HDMI devices.
Version 2.1 of the HDMI specification is backward compatible with earlier versions and was developed by the HDMI Forum Technical Working Group, which comprises some of the world's leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components.
Features of the HDMI 2.1 specification include:
Higher video resolution: it can support a series of higher resolutions and faster refresh frequencies (including 8k60hz and 4k120hz), enabling immersive viewing experience and smooth quick action details. Support up to 10K resolution for commercial AV, industrial and professional applications.
Dynamic HDR ensures that every scene, even every frame, of the video shows the ideal values of depth of field, detail, brightness, contrast and a wider color gamut.
Ultra high speed HDMI cables support 48Gbps bandwidth supported by uncompressed HDMI 2.1 features. The EMI emitted by the cable is very low, which is backward compatible with the previous version of the HDMI specification, and can also be used for existing HDMI devices.
Earc simplifies connectivity, makes it easier to use, and supports the most advanced audio formats and highest audio quality. Ensure full compatibility between audio devices and the upcoming HDMI 2.1 product.
Enhanced refresh rates ensure smoother and seamless movement and conversion of games, movies, and video images. These include:
Variable refresh rate (VRR) eliminates sluggishness, stumbling, and tearing, resulting in a smoother, more detailed gaming experience.
Fast media switching (QMS) for movies and videos eliminates delays that can cause a black screen before displaying content.
Fast frame transfer (QFT) can reduce the delay and make the game and interactive virtual reality more smooth.
The automatic low delay mode (allm) can automatically set the ideal delay settings to achieve smooth, non sluggish and uninterrupted viewing and interaction.
