When buying a television, it is important to learn the difference between full High Definition, HD ready and analog sets with HD converters. Full HD is a term that refers only to sets designated as full HD LCD TV sets or full HD plasma sets.

Full HD – High Definition broadcasts can be received directly only by a set with 1080p pixels. Sometimes this is listed with another number, as in the numbers: 1920 x 1080p. If it is 1080p, then it is either a HD LCD TV set or a full HD plasma set. Unlike analog or HD ready sets, full High Definition LCD TV sets can receive actual high definition television signals at their normal 1080p rate. It can play HD DVDs and blu-ray disks as maximum quality. Like full HD LCD TV sets, full HD plasma sets are fully capable of receiving and displaying 1080p broadcasts.

For blu-ray technology, which is also filmed in this 1080p high definition, these sets are perfectly compatible. These sets reproduce blu-ray disks exactly as they were filmed. Other sets cannot claim quite this high a quality.

HD Ready – HD ready capability exists in sets with a pixel rate of 728i or 1080i. Each set includes a built-in high definition tuner for displaying broadcasts with higher pixel ratings. LCDs and Plasmas have fixed-pixel displays that use pixels to display television images. If the number of pixels is 728, then it has 728 pixels per vertical inch. If the number is 1080, then it has 1080 pixels per vertical inch. Images increase in detail as the pixel number rises.

Set Sizes – LCDs dominate the market because they come in sets as small as 10 inches and increase in size to family home theater size. Full High Definition LCD TVs often include the 42 inch TV. Full HD LCD TV’s are considered ‘high end’ compared to their HD ready counterparts. Plasma set manufacturers sometimes offer a 42 inch TV, which may or may not be a full High Definition plasma set. However, plasmas are most often in giant sizes, such as 50 inches and 60 inches. They are primarily for home theater use. Full HD plasma sets are “high end” compared to similarly-sized HD ready plasma sets. Already generously large, the 42 inch TV is the smallest size where both plasma and LCDs are available.

HD Sets – High definition television is broadcast in widescreen, also known as the 16 inch by 9 inch ratio. Analog television was always broadcast in 4:3 ratio. Whether they are HD ready or full HD LCD TV sets, LCDs will all come with wider screens. For full HD plasma sets, these sets will be wider than analog sets, but of course HD ready plasmas are also wider. Width is not an indication of HD quality, simply of HD capability.

HD Converter – For analog television users, an High Definition converter is a must. Almost all analog signals have been or are being replaced by digital signals. Only an HD converter can make an HD broadcast into an analog signal. Many users report that an HD converter has improved their analog picture considerably. Still, this is not a full HD picture as defined by manufacturing standards.

HD Online – Many television shows are now offer HD broadcasting online. This may or may not be full HD internet by manufacturing standards. After all, your computer also has a tuner that will simply convert any 1080p HD online internet signals into a lower pixel rate as needed.
