Three HDMI inputs allow you to connect a Sony Playstation, Blu-ray disc player, and another HD-enabled device. A variety of additional inputs makes it simple to connect surround-sound systems, other entertainment gear, and even a computer. Note: You must have a source of HD programming in order to take full advantage of an HDTV. Otherwise, the picture quality of an HDTV without an HD source may not be much better than that of a standard-definition TV. Please contact your local cable or satellite TV provider for details on how to upgrade to HD programming.
