This Energy Star-compliant model features a tuner that can receive conventional analog channels (NTSC), as well as digital channels (ATSC), including over-the-air HDTV broadcasts where available, and unscrambled digital cable channels. Two HDMI inputs and a variety of other inputs make it simple to connect DVD players, surround-sound systems, other entertainment gear. 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.
