Directional Active High Speed HDMI Cable with built-in IC Booster 4K & HDR Support – 130 Feet This Cmple High Speed HDMI cables with Ethernet are designed with built-in signal equalizer for applications that require high-performance transmission of HDMI digital video and multi-channel audio signals. These cables have active amplification built-in to prevent impedance mismatch, caused by the cable attenuation, dielectric losses and compensation for skin effect over long distances. The built-in booster does not require an external power, since it is using the 5-volt from pin-18 on the HDMI cable extracting the power from the display.
