On Tuesday 28 November 2017, the HDMI Forum finally released the new HDMI specification, HDMI 2.1, to all vendors who have already adopted HDMI 2.0, according to a report from Neowin.
The specification, which was originally unveiled back in January 2017, will also be backwards compatible with all previous HDMI specification.
According to a report by Engadget, some of the new specifications include:
- Higher video bandwidth
- Supports 48 Gbps
- Faster refresh rates for high video resolution — 60 Hz for 8K and 120 Hz for 4K
- Dynamic HDR
- Supports resolutions up to 10K for commercial and speciality use
This new version will also look to eliminate lag for smoother gameplay with a Variable Refresh Rate (VRR), while Quick Frame Transport (QFT) reduces latency, which will no doubt please the gaming community. While Quick Media Switching, or QMS, reduces the amount of blank-screen wait time while switching media.
HDMI 2.1 also includes Auto Low Latency Mode (ALLM), which automatically sets the ideal latency for the smoothest viewing experience. Just to clarify, you do not need to rush to the store to go and buy the new version and upgrade all your equipment. As 4K is only starting to gain real commercial traction, the introduction of the new specifications is mainly future facing.
