Using this AV adaptor is easy. First, find the Mini DP port on your Apple device like a Mac mini, Macbook, or iMac. Plug one end of the adaptor into this Mini DP port. Then, locate the HDMI input on your HDTV or computer monitor and connect the other end of the adaptor to it. Once connected, your device should automatically detect the new display, and the audio and video will start playing on the monitor. When handling the adaptor, be gentle with the connectors. Avoid pulling the cable too hard as it might damage the internal wiring. For storage, keep it in a cool and dry place. If the outer jacket gets dirty, you can use a soft, dry cloth to wipe it clean. Don't use any harsh chemicals as they could damage the PVC material.
