Introducing Tera Grand HDMI 2.1 8K Ultra High Speed HDMI Cable

What is HDMI 2.1?
HDMI® Specification 2.1 is the most recent update of the HDMI specification and supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps.

Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable. The cable ensures ultra high-bandwidth dependent features are delivered including uncompressed 8K video with HDR. It features exceptionally low EMI (electro-magnetic interference) which reduces interference with nearby wireless devices. The cable is backwards compatible and can be used with the existing installed base of HDMI devices.

What’s new in HDMI 2.1?
HDMI 2.1 significantly increases bandwidth to 48Gbps and includes the following advanced features:
  • Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 10K are also supported for commercial AV, and industrial and specialty usages.
  • Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.
  • Features very low EMI emission
  • eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality.
  • Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
  • Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.
  • Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
  • Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.


    What is an Ultra High Speed HDMI Cable?
    The Ultra High Speed HDMI Cable is the first cable defined by the HDMI Forum. Ultra High Speed HDMI Cables comply with stringent specifications designed to ensure support for high resolution video modes such as 4Kp50/60/100/120 and 8Kp50/60 as well as new features such as eARC and VRR. Ultra High Speed HDMI Cables exceed the requirements of the latest international EMI standards to significantly reduce the probability of interference with wireless services such as Wi-Fi.

    Is this cable required for delivering HDMI 2.1 Specification features?
    The cable is the best way to ensure that high-bandwidth dependent features are delivered including the enhanced video and audio performance, and accounting for the new EMI characteristics.

    Is HDMI 2.1 Specification backwards compatible with previous versions of the specification?

    Can the Ultra High Speed HDMI Cable work with existing HDMI devices?
    The cable is backwards compatible and can be used with all existing HDMI devices.

    What connectors do the Ultra High Speed HDMI Cable use?
  • It is compatible with HDMI Category 3 connectors Types A, C and D.
    What are the supported resolutions and frame rates?
  • 4K50/60
  • 4K100/120
  • 5K50/60
  • 5K100/120
  • 8K50/60
  • 8K100/120
  • 10K50/60
  • 10K100/120

  • Will 8K@60 or 4K@120 require a new cable?
    Yes, in order to ensure performance and compatibility, an HDMI 2.1 Ultra High Speed HDMI Cable is required.

    Can my existing HDMI 1.4 devices be upgraded with HDMI 2.1 features?
    Currently, there are no provisions for doing such an upgrade. Because of the new enhanced feature set, any such conversion would require hardware and/or firmware upgrades.

    Does the Ultra High Speed HDMI Cable have an Ethernet channel?
    Yes, it supports the HDMI Ethernet Channel.

    Does Dynamic HDR require the new Ultra High Speed HDMI Cable?
    No, but it will be necessary to enable 4K120 and 8K60 video with HDR due to the high bandwidth required by these resolutions and refresh rates.

    Which HDR formats does the specification support?
    It supports various static and dynamic HDR resolutions.

    How does the specification support multiple HDR solutions?
    Static and Dynamic HDR-enabled devices that implement the HDMI 2.1 Specification transmit both Static and Dynamic HDR metadata over the HDMI interface in a standardized way; and also go through the same mandatory HDMI compliance testing to ensure they can properly send/receive Static and Dynamic HDR metadata over the HDMI interface regardless of product manufacturer. This ensures consumers can get all the benefits of Dynamic HDR without possible compatibility issues.

    What features are added to HDMI 2.1 for video gaming and media playback?
    HDMI 2.1 has added the following new features:
    • Auto Low-Latency Mode (ALLM)
    • Variable Refresh Rate (VRR)
    • Quick Frame Transport (QFT)
    • Quick Media Switching (QMS)
