A:Answer HDMI is a standard protocol for sending audio video signals, much like USB or an old serial port on a computer. So if your devices are HDMI compatible, it's just a matter of having the right connector. This cable has full size connections, your phone likely has a mini HDMI, so this probably won't work. You'll need to match the connectors for your specific phone. If you have a smart tv, or a dongle like Amazon tv or apple tv, you could wirelessly connect through those devices.
