DESC: The Vizio 32'' Eco HDTV uses nearly 44 percent less power than conventional 32" class LCD HDTVs. It requires only 84watts of energy to deliver quality 720p entertainment. The tuner 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, camcorders, digital cameras, or even a computer. You must have a source of HD programming in order to take full advantage of the Vizio 32'' Eco HDTV. Otherwise, the picture quality of an HDTV without an HD source may not be much better than a standard-definition TV.
