HDMI 2.1 can support 10K resolution and Dynamic HDR


Back in Jan, the HDMI Forum unveiled its new specifications for the HDMI connector, called HDMI 2.1. Now, that HDMI specification is available to all vendors who have already adopted HDMI 2.0. It’s backward compatible with all previous HDMI specifications.

The focus of HDMI 2.1 is on higher video bandwidth; it supports 48 Gbps with a new backward-compatible ultra high-speed HDMI cable. It also supports quicker refresh rates for high video resolution — 60 Hz for 8K and 120 Hz for 4K. The standard is also supported Dynamic HDR formats and resolutions up to 10K for commercial AV and specialty use.

This new version of the HDMI specification also introduces an enhanced refresh rate that gamers can appreciate. Variable Refresh Rate (VRR) Refresh Rate, reduces, or in some cases eliminates, lag for better gameplay, while quick Frame Transport (QFT) reduces latency. quick Media switching, or QMS, reduces the amount of blank-screen wait time while switching media. HDMI 2.1 includes auto Low Latency Mode (ALLM), that automatically sets the ideal latency for the smoothest viewing experience.

If you are not certain what this HDMI upgrade means that, this handy chart provided by the HDMI forum makes it clearer. you’ll clearly see how upgraded specifications have increased support for different features as specifications improved.
