FAQ

You should plug the HDMI CEC adapter into the output port of the offending source device (like a Fire TV Stick, Apple TV, PC, or gaming console) before connecting your HDMI cable. Note: Do NOT use this adapter on the ARC/eARC port of your TV or directly on the connection going to your soundbar, or you will lose audio sync features.

Yes, the 24K gold-plated connectors ensure optimal performance by maximizing signal strength and lowering resistance. The gold plating also prevents oxidation and corrosion, guaranteeing the adapter outlasts standard metal alternatives.

Not at all. The adapter passes all high-speed video channels completely untouched. It fully maintains 4K UHD playback, HDR formats, and high-frame-rate passes without introducing lag or signal degradation.

Pin 13 is the dedicated physical wire inside a standard HDMI architecture responsible for carrying Consumer Electronics Control (CEC) commands. By structurally disconnecting Pin 13 inside this housing, the adapter physically blocks communication commands (like auto power-on or auto-input switching) while leaving the remaining 18 pins entirely free to pass video, audio, and network data safely.
