HDMI Forum today announced the upcoming release of Version 2.1 of the HDMI specification, designed for higher video resolution, refresh rate and increased bandwidth.
HDMI Specification 2.1 features refresh rates of 8K-60Hz and 4K-120Hz for more immersive viewing and smooth fast-action detail, the Forum said. The new spec also supports dynamic HDR.
With the use of a 48GB cable, the HDMI 2.1 enables up to 48Gbps bandwidth for uncompressed feature support including 8K video with HDR. The cable is backwards compatible.
The spec's eARC supports advanced audio formats such as object-based audio and enables advanced audio signal control capabilities including device auto-detect.
Game Mode VRR features variable refresh rate, which enables a 3D graphics processor to display the image at the moment it is rendered for more fluid and better detailed gameplay, the company said, and for reducing or eliminating lag, stutter, and frame tearing.
The new specification will be available in Q2 2017.
“This new release of the specification offers a broad range of advanced features for enhancing the consumer entertainment experience, as well as providing robust solutions to the commercial AV sector,” said Robert Blanchard of Sony Electronics, president of the HDMI Forum. “This is part of the HDMI Forum’s continuing mission to develop specifications for the HDMI eco-system that meet the growing demand for compelling, high-performance and exciting features.”
