An HDTV-ready TV (also called an "HDTV monitor") has the high-scan-rate display, but must be connected to a separate HDTV tuner to receive digital broadcasts. Most HDTV-ready TVs include an NTSC tuner for viewing regular analog programs. HDTV-ready TVs can have either the conventional 4:3 aspect ratio or the widescreen 16:9 ratio.
* An integrated HDTV combines a high-scan-rate display and an HDTV tuner in one package. The tuner can usually receive both digital and analog over-the-air broadcasts. The FCC (Federal Communications Commission) mandated that as of July 1, 2004, at least 50% of TVs with screens 36" and larger must include an over-the-air digital tuner, and by 2007, all TVs 13" and larger must include a digital tuner. You'll find that nearly all HDTV sets use the widescreen 16:9 aspect ratio.
