HDMI Forum Releases Version 2.1 Of The HDMI Specification

The HDMI forum has released the HDMI 2.1 spec, and promised it can deliver 48Gbps if you buy new cables that support the jump from HDMI 2.0s 18Gbps.

Back in January, the HDMI Forum-the trade association that develops the HDMI spec for video interconnects-outlined its plans for HDMI 2.1. With this bandwidth, it will support resolutions of up to 10K; however, it can run 8K at 60Hz, or 4K at 120Hz.

Videos also get a boost, mostly due to dynamic HDR, which allows a video to send high-dynamic range metadata to your HDR television scene-by-scene or even frame-by-frame basis, rather than simply at the start of a video.

There's also a new cable, the Ultra High Speed HDMI Cable, which supports up to 48 Gbps of bandwidth and features a very low level of EMI emission. For those who don't know, HDR stands for high dynamic range, which essentially offers higher contrast, vivid colours and near retina-searing brightness for compatible TVs and displays; Dynamic HDR does that but adjusts the settings on the fly to correspond with what's being displayed, which is pretty cool if you like that sort of thing.

Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable.

The new spec will be backward compatible which means that a new device based on HDMI 2.1 spec will work without any hassle with devices based on the older HDMI 2.0 or HDMI 1.4 spec.

Additional features of the new standard includes eARC, which is designed for simplified connectivity and supports advanced audio formats, ensuring compatibility between audio devices and upcoming HDMI 2.1 products. This includes support for Variable Refresh Rate, which reduces stutter and tearing.

Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality. Lastly, Auto Low Latency Mode (ALLM) is a feature that sets the ideal latency for smooth, lag-free viewing.

Not many people will likely be too excited about the latter, but after the glut of cheaper 4K tellies that cropped up in the Black Friday sales, better 4K frame rates has a bit more pull to it.
