Why choose it

This cable overcomes the length limitations of traditional copper HDMI cables.

Gold-plated connectors resist corrosion and ensure reliable contact, while the directional design simplifies correct installation. It supports the latest HDMI 2.1 features, so you can enjoy 8K resolution, high dynamic range, and smooth gaming without compromise.

Ideal use cases

• Connecting an 8K media player or gaming console to a TV or projector across a large living room
• Professional AV installations in conference rooms, lecture halls, or home theaters
• Running cables through walls or conduits where signal integrity over distance is critical
• Gaming setups requiring VRR and ALLM for tear-free, low-latency play at 4K 120 Hz

Good to know

The cable is directional: one connector is labeled for the source device, the other for the display. It draws power from the HDMI port, so no external power supply is needed. Ensure your devices support HDMI 2.1 to take full advantage of 8K and 48 Gbit/s bandwidth. For lower resolutions, the cable is backward compatible with earlier HDMI standards.
