performance HDMI 2.1 cable engineered for uncompromised audiovisual quality, low latency, and futureproof bandwidth. Key benefits — why you need it Immersive, synchronized audio and video: eARC and automatic A/V sync deliver lossless multichannel audio and picture in sync, eliminating lip‑sync issues and simplifying setups with soundbars or AV receivers. Smooth, tear visuals for gaming and movies: VRR, ALLM, QMS, and QFT reduce stutter, reduce input lag, and enable instant source switching so gameplay and fastaction content feel responsive and fluid. Futureready bandwidth and resolution: With a 48 Gbps link and support for 8K video, this cable ensures compatibility with the latest TVs, consoles, and GPUs without compromising frame rate or color depth. Technical highlights and performance HDMI standard/features: HDMI 2.1 with Enhanced Audio Channel (eARC), Fast Media Switching (QMS), Variable Refresh Rate (VRR), Automatic Low Latency Mode (ALLM), and Quick Frame Transmission (QFT). Resolution and refresh rates: Supports up to 8K (7680 × 4320) at 60 Hz; 4K at 120 Hz; 2K (1440p) at 144 Hz; 1080p at 240 Hz. Also supports 3D video formats. HDR support: Static HDR metadata and Dynamic HDR processing for improved contrast and color framebyframe. Audio capabilities: eARC supports multiple audio streams and up to 32 audio channels; automatic audiovideo synchronization; 1536 kHz audio sampling rate for fidelity sound. Bandwidth: Full 48 Gbps total bandwidth to handle resolution, framerate content and rich audio data. Compatibility and use Works with HDMI 2.1capable devices including modern TVs, AV receivers, soundbars (with eARC), gaming consoles, and graphics cards that require bandwidth and advanced features. Backward compatible with earlier HDMI versions (standard device support will depend on source/display capabilities). What makes it stand out Combines maximum HDMI 2.1 bandwidth (48 Gbps) with advanced audio features (eARC, 32 channels, 1536 kHz sampling) and display features (VRR, ALLM, QMS, Dynamic HDR), delivering a singlecable solution for home theater and competitive gaming setups. Designed for low latency and fast frame handling—ideal when smooth motion and accurate audio timing matter most. Practical scenarios Console and PC gaming: Pair with a PS5, Xbox Series X, or a refresh PC GPU and a TV/monitor that supports 4K/120Hz or 8K/60Hz to minimize input lag (ALLM), prevent tearing (VRR), and maintain frame rates. Home theater with soundbar or AV receiver: Use eARC to pass multichannel lossless audio from the TV to your sound system while keeping picture and sound synchronized. Multisource living room: Use QMS and QFT for instant, flicker switching between streaming sticks, Bluray players, and game consoles without menu delays or black screens. Quick checklist for buyers Need true HDMI 2.1 features (8K/60Hz, 4K/120Hz, VRR, eARC, 48 Gbps): recommended. If your TV or device lacks HDMI 2.1, the cable remains compatible but device capabilities will limit performance. Ideal when resolution video, fast refresh rates, or multichannel lossless audio are required. Specifications (concise) HDMI version: 2.1 Bandwidth: 48 Gbps Video: 8K (7680×4320) @60Hz; 4K @120Hz; 2K (1440p) @144Hz; 1080p @240Hz; 3D supported HDR: Static HDR and Dynamic HDR supported Features: eARC, QMS, VRR, ALLM, QFT Audio: eARC multistream support, up to 32 audio channels, automatic A/V sync, 1536 kHz sampling rate Minimal setup tips Ensure both source and display/receiver support the desired HDMI 2.1 features. Use the shortest practical cable run for signal integrity, especially at the resolutions and refresh rates.
