Cáp HDMI tiêu chuẩn với dây CEC đầy đủ để điều khiển thiết bị (một remote cho TV + soundbar + Blu-ray). Tất cả cáp HDMI hiện đại đều hỗ trợ CEC nhưng loại rẻ đôi khi bỏ qua chân 13.
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.
