What is the difference between HDTV and HD-Ready televisons?
HDTVs contain an HD tuner allowing you to receive high definition, for example from your house antenna’s over the air signal reception. HD_READY TVs contain everything necessary to display high definition except that HD tuner. To display high definition, you need a separate high definition tuner box (ca. $300) or cable (or other service) which provides a high definition digital cable box which does the tuning for high definition for you.
