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 - A full High Definition plasma set should have a pixel count that is labeled 1080p. Generally it has a contrast ratio designation as 1920 by 1080p. A full HD LCD TV set should also have a pixel count label as 1080p. You may also see the contrast ratio is designated as 1920 by 1080p. With this 1920 by 1080p ratio, HDTV broadcasting is the best it can be. This is because full High Definition LCD TVs and full HD plasma sets can process and display high definition 1080p signals, the highest signals from HDTV. 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 - 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 - 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 - 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. 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. HDTV Online - If you watch television online, you will notice that some shows are offered as HD Online. This simply means that if your computer can broadcast at the 1080p rate, the picture will be full High Definition. If your computer cannot broadcast at this rate and must convert the rate to a lower pixel setting, then the computer can be said to be HD ready.
