What's the difference between HDTV and HDTV Ready?


HDTV (High-Definition Television)
Often mistakenly used as a generic description of all digital television, HDTV specifically refers to the highest-resolution formats of the 18 original DTV formats. Although there still isn't 100% agreement among manufacturers, retailers, journalists, etc., only 1,080-line interlaced (1080i) or 720-line progressive (720p) broadcasts are generally considered to be true HDTV. 1,080-line progressive (1080p) is not an official HD broadcast format, but it is found on high-definition Blu-ray discs and some satellite TV movie broadcasts. And 1080p is now an established standard for HDTV screens.

The term used to describe TVs that could display digital high-definition TV formats only when connected to a separate HDTV tuner. These TVs generally had built-in tuners for receiving regular NTSC broadcasts, but not digital. An HDTV-ready TV could also be referred to as an "HDTV monitor."
