The HD52G787 is ready to deliver HDTV programming right out of the box. With the proper antenna, the built-in digital ATSC/QAM tuning system will receive free over-the-air HDTV signals. But it''s what''s on the screen that counts. Any high definition TV can reproduce high-quality images from high definition sources, but ordinary HDTVs are almost overqualified when it comes to 480i format DVDs or NTSC-TV signals.
