Using this cable is super easy. First, identify the micro - HDMI port on your Raspberry Pi 4B. Then, plug one end of the cable (the micro - HDMI end) into the Raspberry Pi 4B. Next, connect the other end (the regular HDMI end) to your screen, displayer, laptop, or TV. Make sure the connections are firm to get the best picture quality.
When it comes to maintenance, keep the cable away from sharp objects to avoid cuts. If it gets dirty, you can use a soft, dry cloth to gently wipe it. Also, don't bend the cable too sharply as it might damage the internal wires and affect the signal transmission. Store the cable in a cool, dry place when not in use to prevent oxidation and corrosion of the gold - plated interface.
