How to Hook up Surround Sound to an LG 42LD450
The LG 42LD450 is a high-definition TV with a 42-inch diagonal flat screen. The set is equipped with two High Definition Media Interface (HDMI) jacks for audio and video connections to high-definition equipment. One jack is located on the back panel and the second is on the side of the flat cabinet. HDMI cables send video and audio signals through a single connection, so if you want to hook up the LG 42LD450 to surround sound, you will need only one cable with HDMI plugs.
