Planet Waves™ HDMI Cables Gain HDMI 2.1 Certification

Planet Waves™ Ultra High Speed HDMI Cables have gained HDMI 2.1 Certification!  These cables are some of the first in the world to be officially certified. Each cable provides full 8K60Hz Ultra High Definition and 4K120Hz resolution, with support for resolutions up to 10K, frame rates up to 120fps/Hz, and speeds up to 48 Gbps.

HDMI Comparison

The long-awaited HDMI 2.1 Specification recognizes today’s bandwidth-heavy environment by demanding higher speeds for HDMI cables than ever before.  HDMI 2.1’s 48 Gbps transmission is a major step beyond HDMI 2.0’s 18 Gbps, allowing easy support of 4K@120Hz, 8K resolutions, and even future 10K displays.  HDMI 2.1 also requires low electro-magnetic interference, (EMI), helping to avoid conflict with wireless or Bluetooth devices.

HDMI 2.1 features also improve image and sound quality.  Dynamic HDR provides greater detail and more accurate color.  Audio quality is improved by Enhanced Audio Return Channel (eARC), supporting Dolby Atmos® and other high-quality formats.

In addition, HDMI 2.1 improves display performance for gaming and media applications. Features like Variable Refresh Rate (VRR) for decreased lag and Quick Frame Transport (QTS) for reduced latency offer a more seamless experience.

Additional HDMI 2.1 features include:

  • Fixed Rate Link (FRL)
  • Auto Low Latency Mode (ALLM)
  • Quick Media Switching (QMS)

HDMI 2.1 cables are backwards-compatible with earlier HDMI-enabled devices.

Always the “Perfect Length,” Planet Waves™ HDMI cables are available in six lengths from 0.5 meters to 3.0 meters (1.64 feet to 9.84 feet), continuing the Planet Waves tradition of incremental length HDMI for the best-dressed racks and installations.  Like all Planet Waves™ products, each HDMI cable is precision-made under strict manufacturing tolerances.

The new Ultra High Speed HDMI® Cable Certification label will begin appearing on all packaging in Q1 of 2021.  In the interim, understand that no changes have occurred to these HDMI cables.  They were manufactured to pass the HDMI 2.1 certification test from day one.  Cables currently in circulation meet all the requirements of the HDMI 2.1 standard.

Planet Waves™ Ultra High Speed HDMI cables are ideal for pro A/V, gaming, and more.
