The Ethernet cable is part of Local Area Networks used to access wireless Internet or cable connections. An Ethernet cord is plugged into a wireless router to transmit the signal to any Web-enabled device. This is an alternative way to share pictures, games and Web content by transferring the signal to your television screen. Plugging the TV directly into the Ethernet will save the step of using extra cords to route the signal through a laptop or other wireless device. This also cuts out the need for an additional box to make the connection to a wireless signal. LG is one of the only manufacturers producing televisions with an Ethernet jack, as of August 15, 2010. Thus, the Ethernet cord is not compatible with most TVs.
Locate the Ethernet jack on the back of the television. The Ethernet connector looks like a larger version of a typical phone jack. Some models may have a jack in the front lower control panel.
