1. Compatible with HEC (HDMI Ethernet Channel) to realize Ethernet communication with a 48 Gbps transmission rate. It supports ARC (audio return channel), which can transmit digital audio from display devices such as TVs to output devices such as AV amplifiers. 2. The use of gold-plated plugs can prevent rust and suppress signal attenuation. A three-layer shielded cable made of nylon can protect the signal from external noise. It uses a twisted pair structure. 3. Support 60Hz 8K (7680x4320 dots) and 3D full HD (1080p x 4 screen). The color depth supports conventional 24-bit (full color) to 30/36/48-bit (dark), which can achieve richer color performance. 4. Connector type: Micro HDMI to standard HDMI (Type D to Type A) 5.
