This is an HDMI cable from ELECOM! It's 2m long. It was only used once and then stored. Features: ■ This is a super-slim, Ethernet-compatible, high-speed HDMI cable with a cable diameter of approximately 3.2mm, making it easy to handle and allowing for neat wiring. ■ It is a HIGH SPEED with Ethernet certified product. ■ With a single cable, not only can you transmit video and audio signals digitally at high speed, but you can also achieve bidirectional communication of Ethernet signals. ■ It supports HEC (HDMI Ethernet Channel), which enables 100Mbps Ethernet communication. ■ It supports ARC (Audio Return Channel), which allows digital audio to be transmitted from display devices such as TVs to output devices such as AV amplifiers. ■ It supports 3D Full HD (1080p x 2 screens) and 4K2K (4096 x 2160 pixels). ■ Color depth is supported from the conventional 24bit (Full Color) to 30/36/48bit (Deep Color), enabling richer color expression. ■ It uses gold-plated plugs that are resistant to rust and other issues, suppressing signal degradation. ■ It uses a triple-shielded cable to protect signals from external noise interference. ■ It uses a twisted-pair structure that is less susceptible to external noise.
