Demystifying HDMI 2.1 Features vs 2.1 Inputs

Hisense’s 2021 range of TVs boasts a variety of new and enhanced features from previous years. While new technology is exciting, it can also be confusing, so let’s talk about all the new HDMI 2.1.

This year is new territory for everyone around “HDMI 2.1” and it’s important to note that there are two specific topics involved in HDMI 2.1

1. HDMI 2.1 Features

2. HDMI 2.1 Inputs

 

HDMI 2.1 Features Explained

Features for Gamers

Auto Low Latency Mode (ALLM)

This feature lets a gaming console, PC or other device work directly with a television to automatically switch to a low-latency, low-lag mode for gaming. ALLM is designed to subtly improve the experience of your television when gaming, by reducing lag time between the device and your television. Traditionally, gamers would have to manually turn on Game Mode when playing to ensure the best performance possible, but with ALLM these inconveniences are a thing of the past.

This could benefit other uses, such as karaoke and video conferencing. When the source no longer requires this mode—for example, when switching to a movie stream—the source disables the signal, and the display reverts to its previous mode.

 

Variable Refresh Rate (VRR) 

Game consoles often run at different frames per second depending on the complexity of the scene at any given time. Traditionally, a TV expects a constant FPS and when the console cannot provide this, image tearing can occur.

VRR lets a gaming source deliver video frames as fast as it can without tearing or glitches that is experienced when a television is out of sync with a console or device.

A TV that supports VRR will dynamically match its refresh rate to the frame rate of the game, keeping pace with all these changes, resulting in a smoother, more consistent gameplay.

Features for Movie Buffs

Quick Media Switching (QMS)

This feature for movies and video eliminates the delay that can result in blank screens before content is displayed on traditional TVs.

QMS uses the VRR mechanism to eliminate the blackout period when all devices in the HDMI connection chain change video modes. As long as the resolution remains the same and only the frame rate changes, QMS will smoothly switch between frame rates.

 

Enhanced Audio Return Channel (eARC)

eARC expands upon the existing ARC solutions and adds support for the latest high-bitrate audio formats without the need of an optical cable.

If you wish to connect your TV to a home cinema amplifier or surround sound speakers for an enhanced listening experience, this is now done easier than ever before with eARC connecting the dots from a HDMI port to any compatible soundbar or receiver.

eARC supports audio outputs including DTS Master, DTS:X, Dolby TrueHD, Dolby Atmos and more.

HDMI 2.0 Compatibility

These HDMI 2.1 features can be made available on TVs featuring HDMI 2.0 inputs if the TV supports all the other hardware requirements needed. This is known as HDMI 2.1 Partial Compliance.

 

HDMI 2.1 Input Explained

For TVs equipped with the HDMI 2.1 input you will gain access to additional bandwidth support up to 48Gbps (in addition to the HDMI 2.1 Features listed above). The added bandwidth enables higher capabilities like uncompressed [email protected] and uncompressed [email protected] which is great news for bleeding edge gamers who have consoles that support these new modes.
