Cable Matters Active 8K HDMI 2.1 Repeater Coupler (Female to Female), Mountable Extender/Booster, 8K@60Hz 4K@240Hz HDR eARC, for PS5 Xbox Series XS Apple TV RTX 50 RX 9000

Active 8K HDMI Coupler / Repeater for Longer Runs: Join two HDMI cables to extend distance with an active HDMI 2.1 repeater/booster—ideal for home cinema, gaming and projector installs. For best results, use certified Ultra High Speed HDMI 2.1 cables; not designed to fix faulty or low-quality cables. High-Performance HDMI Signal Booster: Supports 8K@60Hz, 4K@240Hz and 4K@120Hz up to 9m, extends up to 15m for 4K@60Hz, and up to 23m for 1080p. Supports CEC, eARC, HDR and HDCP 2.3 for smooth performance with next-gen consoles and HDMI 2.1 PCs. Compact Aluminium Housing, Wall-Mount Ready: Durable metal enclosure improves heat dissipation and resists wear. Clearly labelled INPUT/OUTPUT for quick plug-and-play setup. Includes screws for neat mounting behind TVs, in cabinets, or AV racks for a cleaner install. Optional USB-C Power for Weak HDMI Outputs: USB-C power input (5V/1A) helps stabilise the signal if you see flicker or black screens, or when using devices with lower HDMI output. Use any USB-C charging cable and 5V USB plug (sold separately). Note: Not designed to fix defective or low-quality cables. Important Setup Notes (INPUT/OUTPUT + 8K Cable Limits): Connect INPUT to your source/PC and OUTPUT to your TV/monitor/AV receiver. This repeater boosts signal strength but can’t fix existing ARC/eARC issues or faulty HDMI cables. For 8K@60Hz / 4K@240Hz, keep each side within 4m (HDMI IN) and 5m (HDMI OUT) individually.
