Description

  • 8K Active HDMI Coupler: This active HDMI repeater / HDMI extender / HDMI booster boosts signals by connecting two HDMI cables for longer runs between devices like PS5, Xbox Series X/S, RTX 30/40 GPUs, RX 7900/9000, Apple TV, Blu-ray players, projectors, and more. Use this reliable HDMI booster 8K instead of buying one long, expensive HDMI cable.(Use Certified HDMI 2.1 cables for best results. Not designed to fix defective or low-quality cables.)
  • High-Performance HDMI Signal Booster: This active HDMI cable repeater supports 8K@60Hz, 4K@240Hz, and 4K@120Hz at up to 30ft; extends up to 50ft for 4K@60Hz and 75ft for 1080p Full HD. Supports CEC, eARC, HDR, and HDCP 2.3 for seamless performance.
  • Cinematic Video & Immersive Audio: This active HDMI 2.1 repeater delivers stunning 8K video (4:4:4, 7680x4320@60Hz) per HDMI 2.1 standard. Backward compatible with 4K, 1440p, 1080p, and 3D pass-through, it supports Dolby Digital, DTS, and TrueHD for authentic surround sound.
  • Durable & Wall-Mountable HDMI Amplifier: Compact aluminum enclosure resists wear and enhances heat dissipation. Lightweight design with clearly labeled INPUT and OUTPUT ports ensures simple plug-and-play setup. Includes screws for secure wall mounting in home theaters or AV systems.
  • Optional Power for Weak Signals: This 8K HDMI coupler female to female includes a USB-C power option (5V/1A) using a charging cable and wall charger (sold separately). It’s ideal for extending connections from tablets, notebooks, or devices with low HDMI signal output to TVs and projectors. For long cable runs, AVRs, projectors, weaker HDMI outputs, flickering screens, or blackouts, connect the USB-C power to stabilize the signal.
  • Important Notice: Connect INPUT to your source or computer and OUTPUT to your TV, monitor, or AVR. For best performance, use certified Ultra High Speed HDMI 2.1 cables. This repeater boosts signal strength but cannot fix existing ARC/eARC issues or faulty HDMI cables. Cable length limits apply to each side individually: up to 13.1ft (4m) for HDMI IN and 16.4ft (5m) for HDMI OUT when transmitting 8K@60Hz / 4K@240Hz.
