Hdmi Extension Cable is a common device used to extend the transmission distance of HDMI signals. The following are the detailed steps and precautions for using HDMI extension cables:
1. Confirm device compatibility
Before connecting, make sure that all your devices (e.g. Blu-ray players, computers, TVs, etc.) support HDMI connection and the HDMI extension cable is compatible with the devices.?
2. Power off
Before connecting the HDMI extension cable, make sure all related devices are powered off to avoid damaging the devices or causing signal interference.
