HDMI 2.1 cables are the latest in tech! Enjoy faster data transfer rates and enhanced video and audio. These cables support higher resolutions, increased refresh rates, and gaming features like VRR and ALLM.

Uncompressed 8K video at 60Hz or 4K video at 120Hz? That’s right – sharper images, smoother motion, and a more immersive viewing experience. Plus, up to 48Gbps of bandwidth for minimal latency and maximum data transfer speeds.

Gamers and movie lovers – upgrade your setup with HDMI 2.1 and unlock a world of possibilities! Remember, not all HDMI cables are the same. Look for “8K,” “4K/120Hz,” or “HDMI 2.1” on the cable packaging or product description for true HDMI 2.1 technology.

What is HDMI 2.1?

HDMI 2.1 is the most recent version of the High-Definition Multimedia Interface. It is widely used to transmit audio and video signals between devices. This upgraded version has many improvements over its predecessors.

It boasts support for higher resolutions and refresh rates. This means resolution up to 10K and refresh rates up to 120Hz. This new standard delivers clear, smooth imagery.

It also has Variable Refresh Rate (VRR) technology. This syncs the display’s refresh rate with the graphics processor. This eliminates screen tearing and stuttering for gamers.

Quick Frame Transport (QFT) is another feature of HDMI 2.1. This reduces latency for faster gaming response times. Plus, there’s Auto Low Latency Mode (ALLM). This automatically switches to game mode to reduce input lag when connected to a gaming console or PC.

Audio capabilities include Enhanced Audio Return Channel (eARC). This allows high-resolution audio formats such as Dolby TrueHD and DTS-HD Master Audio over a single HDMI connection. This provides immersive sound quality.

HDMI was first developed in 2002 by several leading companies. Since then, HDMI has had several upgrades to meet technology needs.
