If you're unfamiliar with the ports on your TV, most newer TVs support HDMI-CEC (Consumer Electronics Control). Essentially, the HDMI-CEC port supports one remote to control all of your devices. However, not all TV manufacturers refer to this port as simple 'HDMI-CEC.' For example, Philips lists its port as EasyLink, and Sony lists its port as BRAVIA Link. It's best to look at your TV's manual for the best port to use with your Firestick.
