Full HD TV Explained
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.
Full High Definition plasma sets also play blu-ray at its highest capacity and high definition DVDs as well. Full HD LCD TV sets broadcast in widescreen as do full HD plasma sets.
HD Ready - Full HD LCD TV sets and full High Definition plasma sets are different from those that are simply HD ready. HD ready is indicated by a 728i or 1080i pixel rate. HD-ready sets have tuners to adjust for the difference between their pixel rates and High Definition broadcasting. These sets are reported to have good pictures for their price range and compare favorably with full HD plasma sets and full High Definition LCD TV sets.
Set Sizes - HD ready and full HD LCD TV sets can come in smaller sizes. LCD sets actually come in small sizes such as 10 inches. Sizes used to stop as a 42 inch TV but now are as large as 60 inches. HD ready and full HD plasma sets come in 50 or 60 inch sizes usually. It is possible now to get a 42 inch TV plasma set from some manufacturers. Keep in mind that similar size does not mean the same picture quality.
HD sets - One obvious difference between analog and full High Definition TV broadcasting is the aspect ratio. This is the width by height of a display. Analog broadcasting had an aspect ratio of four inches of width to three inches of height. HDTV broadcasts in a 16:9 ratio. You can expect a full HD LCD TV to be as wide as it is tall. It is thinner due to its streamlined technology, and its thinness is not a way to determine if a set is HD ready or a full High Definition LCD TV. Due to aspect ratio, full HD plasma sets and HD ready plasma sets may be as wide as they are tall. They are also thinner due to their technology, and thinness cannot be used as a guide to HD capabilities.
HDTV Converters - High Definition TV converters can be used with analog televisions, also known as CRTs or crystal ray cathode sets. These HDTV converters are digital tuners that adjust for the switch-over to digital broadcasting. With an High Definition TV converter, an analog set can deliver superior pictures to its analog ones. An HDTV converter is essential to receive signals on analog sets now that almost all signals are digital.
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.
