Running an HDMI cable 50 to 75 feet from a media rack to a ceiling-mounted projector — and passive cables show snow, sparkles, or no signal at all? Standard HDMI loses too much signal at that distance for 4K to work passively. This Active HDMI cable has a built-in signal equalizer that recovers 4K bandwidth lost over long passive runs, and the CL3-rated jacket meets fire safety code for residential in-wall installation in higher-voltage classes. Built with active signal equalization circuitry, tinned copper conductors, foil + braid double shielding, gold-plated connectors, and a CL3-rated PVC jacket. Compatible with PS5, Xbox Series X/S, AV receivers, ceiling-mounted projectors, classroom TVs, conference room displays, and any 4K HDMI source — directional cable: the SOURCE end must connect to the source device. Supports 4K@30Hz, 1080p, HDR10, ARC, CEC, and HDMI Ethernet Channel up to 10.2 Gbps. Best for: long passive in-wall runs to ceiling projectors and far-wall TVs. Not for: plenum spaces, 4K@120Hz, or 8K. RoHS compliant.
