This cable is the latest generation of HDMI technology, built to handle the highest-resolution video, fastest refresh rates, and most advanced audio formats available today.
HDMI 2.1: This is the current latest standard for the High-Definition Multimedia Interface.
Ultra High Speed: This is the official cable designation for HDMI 2.1. This certification guarantees the cable can handle the immense data requirements of the new standard.
48Gbps: This specifies the maximum data transfer bandwidth.
8K: The cable supports the maximum video resolution of 7680 x 4320 pixels at a smooth refresh rate (typically 60Hz).
UHD (Ultra High Definition): This is a general term encompassing both 4K and 8K resolutions, confirming the cable is suitable for high-definition viewing.
4K@120Hz: While 8K is its max resolution, the 48Gbps bandwidth is primarily used to enable extremely high frame rates for lower resolutions, such as 4K resolution at 120Hz.
The HDMI 2.1 specification (which this cable supports) enables several critical advanced features:
eARC (Enhanced Audio Return Channel): Allows the transmission of uncompressed, high-bitrate, object-based audio formats like Dolby Atmos and DTS:X from your TV back to a sound bar or AV receiver.
VRR (Variable Refresh Rate): Synchronizes the display's refresh rate with the console's output, eliminating screen tearing and stuttering for much smoother gameplay.
ALLM (Auto Low Latency Mode): Allows the gaming console (like the PS5 or Xbox) to automatically switch the connected TV into its low-latency Game Mode for minimal input lag.
Dynamic HDR: Supports advanced HDR formats like HDR10+ and Dolby Vision, which adjust color and brightness levels on a scene-by-scene or frame-by-frame basis for incredible picture depth.
Gold: Refers to the gold-plated connectors on the ends of the cable.
PS4, PS5, XBOX (Series X|S & One): This highlights its use for modern and next-generation gaming consoles, which are the main devices that require and benefit from HDMI 2.1 features like 4K@120Hz and VRR.
Sky, Virgin, HDTV: Confirms its compatibility with general home theater and media devices, including older TVs and modern set-top boxes, thanks to backward compatibility with previous HDMI standards.
