Samsung has earned a good name for itself in the field of home appliance electronics manufacturing. Their line of HDTV sets is a feather in their cap. There all sorts of models launched by the giant Plasma, LCD and DLP. Although the initial prices are high in accordance with the market trend, it is expected to dip soon.

The new range of models emphasize larger screens and higher resolutions like a 42" monitor, 10000:1 contrast ratio and a 549 billion colors display. The soaring contrast ratio of the latest models might portray an interesting statistical picture, but the consumer needs to understand that the human eye has a limit of perceiving images and its visual system cannot discern the offered resolutions. Basically, the higher the contrast ratio, the better the display is, but anything beyond the eyes range doesnt really make much sense.

Samsung offers a number of models to choose from. The basic difference in all the models are their types, size, price and add-on features like input/output slots and ports, PC card slots or SD slots, more speakers, hidden speakers etc. The most popular ones among buyers are models ranging from 42" to 63" with customized mini details like in-built cards (which discard the need of external cable box) and hi-fi speaker systems. The presence of the HDMI (High Definition Multimedia Interface) and component ports is a must for every HDTV set. It is to ensure a good picture quality from the DVD player.

Some of the best-seller HDTVs in the market are the LCD line, which is a good option lower cost in lieu of a 'smaller' screen. The LCD comes in a range of 32" to 46". The 46" LN-S4692D model is a flat-panel display on a swivel stand, which provides a 178 degrees view angle. Its contrast ratio is a decent 5000:1. The smaller 40" LN-S4051D version is usually used by gamers using an Xbox. A contrast ratio of 4000:1 and 8 ms response times in the set is ideal for both gaming and TV use owing to its undetectable motion blur.

The DLP style TV models of Samsung come in a variety of small sizes -50" HL-S5065 and the larger- 71" HL-R7178W models offering excellent picture quality. The largest of all the 71" HL-7178 contains a digital cable-ready card and 1080p video support scoring over the competitor, Panasonic. Even the smaller versions like the 56" HL-S5688W are designed to provide excellent quality 1080p pictures and come equipped with a 14,400 rpm color wheel which minimizes the 'rainbow' effects.

The specifications indicate the letters - 'i' and p. The I model uses the interlacing illumination technique in which the pixel rows brighten every other line, painting the complete screen in two passes. The 'p' type illuminates in a single pass across the screen. The 'p' types are known to offer a superior picture, but interlaced models are not inferior. Although some older i models suffered from some flicker with interlacing, this is being rectified now.

Many less expensive HDTVs come without an in-built HD tuner or HD-ready types. This deficiency is overcome by tuners provided by the cable or satellite boxes without a performance loss. HD-ready are generally less expensive, all other things being equal.

The cost price of an HDTV is defined by the screen size and resolution and some extra add-ons. A careful cost and functions comparison must be made before going in for any TV set.
