标准HDMI线缆，具备完整CEC引脚布线，支持设备控制（一个遥控器控制电视+音响+蓝光播放器）。所有现代HDMI线缆都支持CEC，但廉价产品有时会省略第13针。
Consumer Electronics Control relies on pin 13 of the HDMI connector, and a CEC-enabled cable guarantees that conductor is wired so a single remote can operate a television, soundbar, and Blu-ray player together. Every modern HDMI specification includes CEC, but inexpensive cables sometimes omit the pin, breaking the feature silently. Beyond that wiring detail it is a standard HDMI 2.0 cable at 18 Gbps for 4K at 60 Hz. A 5-meter length covers typical equipment-rack distances. Home-theater setups that chain device control across brands depend on the full pinout. Correctly wired cables cost $5 to $15.
