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.

Boost your HDMI performance with the Cable Matters 8K Active HDMI Coupler. This HDMI repeater / HDMI extender / HDMI booster supports up to 8K @ 60Hz and 4K @ 240Hz, ensuring crystal-clear video and immersive audio. Ideal for long HDMI runs between devices like PS5, Xbox Series X/S, RTX GPUs, and projectors. (Use Certified HDMI 2.1 cables for best results.)

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Cable Matters products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
