Technical Overview
This HDMI 2.1 cable utilizes a 19-conductor design with 30/32 AWG wiring to maintain signal quality over its 1.6-foot length. It supports resolutions up to 7680 x 4320 (8K) at 60Hz and 4K at 120Hz, with full bandwidth for 48Gbps data transfer. The cable is backward compatible with HDMI 2.0b, 2.0a, 2.0, and 1.4 devices, ensuring broad system integration.
Advanced shielding combines aluminum Mylar foil, braided aluminum, and die-cast aluminum to effectively block electromagnetic interference. This multi-layer approach prevents signal degradation in electrically noisy environments. The cable's passive design requires no external power, while strain reliefs at both connectors enhance mechanical durability.
