Samsung 22 Inch LCD TV, LN22B650, 720p

The NTSC (National Television Systems Committee) has established the color standards all TVs in America try to meet. And typical LCD TVs only meet about 72 percent of this standard. Samsung LCD HDTVs use Cold Cathode Fluorescent Lamp backlights to give you 92 percent coverage of the NTSC standard, ensuring truer, more breathlessly vivid colors.

Samsung's Wide Color Enhancer 2 technology delivers more brilliant colors by expanding the gamut of color expression into a third axis, creating a 3D diagram of luminance. This creates a dynamic display of on-screen color and allows traditionally weak colors, such as green and blue, to look vivid and deep. In addition, red colors are enhanced to provide strong colors across the spectrum and the perfect balance of RGB.

With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.

If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.
