How to use

Connect one HDMI Type A end to the HDMI output of the source device and the other end to the HDMI input of the display or AV equipment. Ensure both devices are powered off when making the connection to avoid hot-plugging issues, then power them on and select the appropriate HDMI input on the display. If using ARC, enable ARC settings in both the TV and the audio device according to their manuals. Route the cable carefully to avoid sharp bends and protect it from pinching or crushing during installation.

Recommendations

The cable is intended for direct HDMI connections over 20 m; for installations requiring frequent movement or exposure to mechanical stress consider protective conduit or cable management. Verify device compatibility for 3D and ARC features and enable corresponding settings in device menus when necessary.
