The UGREEN 8K HDMI Fiber Optic Cable (50M) is engineered for those who need to transmit ultra-high-definition visuals across significant distances without the signal degradation common in traditional copper cables. By utilizing advanced fiber optic transmission, this cable ensures stable, lossless data flow over its full 50-meter length, making it an ideal solution for large-scale home theaters, professional AV setups, and gaming environments. Performance is at the core of this cable, supporting the HDMI 2.1 standard with a massive 48Gbps bandwidth. This allows for breathtaking 8K@60Hz and 4K@120Hz resolutions, ensuring that high-frame-rate gaming and cinematic content remain fluid and crisp. It also integrates cutting-edge technologies including Variable Refresh Rate (VRR), Quick Media Switching (QMS), and Auto Low Latency Mode (ALLM) to minimize lag for a more responsive experience. Audio quality is equally prioritized with support for Enhanced Audio Return Channel (eARC) and a wide array of high-fidelity formats, including Dolby Atmos, DTS:X, and Dolby TrueHD. This ensures that your visual experience is matched by immersive, object-based surround sound. Built for durability and reliability, the cable features gold-plated, corrosion-resistant connectors enclosed in a robust zinc alloy shell. The outer jacket is crafted from flexible TPE, providing excellent longevity and easier cable management during installation. Please note that this is a directional (one-way) cable; for proper functionality, the 'Source' end must be connected to the output device and the 'Display' end to the screen.
