Using this Prolink adaptor is a breeze. First, find the DisplayPort on your Apple Mac Notebook or desktop computer. Plug one end of the adaptor (the DisplayPort plug) into this port. Then, locate the HDMI input interface on your HDTV or computer display monitor. Connect the other end (the HDMI - A socket) of the adaptor to this interface. Once connected, turn on both your source device and the display device. The audio and video content from your Apple device should now appear on the monitor. Here are some things to keep in mind. Avoid bending the cable sharply as it might damage the double - shielded oxygen - free copper inside. When not in use, store the adaptor in a cool and dry place. To maintain it, you can use a soft, dry cloth to gently wipe the connectors. This will help keep the 24K gold - plating in good condition and ensure a stable connection. With proper use and care, this adaptor will serve you well for a long time.
