Panasonic TH-58PZ750U HDTV

Short for high-definition television, HDTV is a generation of television first approved by ATSC on December 24, 1996, that offers higher resolutions and clarity.

HDTV resolutions

The HDTV standard defines display resolutions of:

  • 1080i (1,080 lines of pixels in an interlaced configuration)
  • 720p (720 lines, progressive)
  • 1080p (1080 lines displayed progressively)

1080p technically falls into the category of FHD (Full High Definition), not HD like 720p and 1080i. But, a television with this resolution is still called an HDTV.

HDTVs are displayed on a wider screen because of the 16:9 aspect ratio although not all wide screen displays are capable of displaying HD. The picture is an example image of a 1080p HDTV, the Panasonic TH-58PZ750U.

The cutoff date for the last analog signal to transmit was June 12, 2009. After that, all broadcasts moved to digital high-definition in the United States.
