Using this mini HDMI to HDMI adapter is a breeze. First, plug the mini HDMI end of the adapter into your device with a mini HDMI port. Then, connect your regular HDMI cable to the standard HDMI jack on the adapter. That's it - you're all set to use your classic HDMI cables with your device. As for the color, remember that it could be black or white, but don't worry, they both function the same. There's no special maintenance required. Just keep it clean and dry, and avoid bending or pulling on the adapter too hard. If you have any issues, feel free to reach out to us.
