The Samsung LN52A650 HDTV which is a full high definition television, is for its price and class one of the best available on the market.
Samsung has utilized many award winning technologies in the design and also the engineering of their HDTVs.

Samsung offers the consumer several different television models.

The 650 line is their mid-range line. The model 650 line is not their flagship line, but it is also not for the novice just entering the HDTV realm.
It was designed for the person who has some familiarity with HDTVs, but isn't equipped with every feature known to man, either.

The LN52A650 has a screen size of 52 inches. The 52 inch screen needs to be seen from the right distance and therefore needs to be in a room big enough to be far enough away from the screen. The rule of thumb for the distance in viewing a HDTV is roughly 1.5 to 3 times in inches the size of the screen.

Thus, if you have a 52 inch HDTV, you would need at least 6.5 feet from the screen to feel comfortable seeing it. The TV should also not be farther away than 13 feet.

This particular model has 50000:1 dynamic contrast ratio, up from 25000 on earlier models. Basically, the higher the number the better the contrast is.
The 50000:1 will give you very sharp clarity and color. Each color, including black and white will be truer and sharper. You will also get more gradations of colors.

With a 4 millisecond response time you get amazing fast action scenes. Samsung uses this very fast response time along with a new technology they developed called Automotion Plus 120 hz blur reduction to make the viewing almost as if you were seeing it live.

In order to truly appreciate the fast response time and the Automation Plus technology, you should understand what happens with most HDTVs. Normally, even in some more expensive TVs, when there are fast action scenes on TV, such as football, running, car chases or any other fast motion, the action tends to get blurry.

The samsung ln52a650 lcd HDTV does not show action sequences smudged or blurry. The refresh rate and response time enable you to see someone running, for example, very clearly without blurring. You can actually see their legs moving clearly. It's almost as good as seeing it in person.

Samsung also uses a cold cathode flourescent lamp in the HDTV. The idea of a flourescent lamp sounds awful, because we think of sterile interior lighting. But in this case it dramatically improves the color.
This lamp actually allows the 650 model line to achieve 92% of the NTSC (National Television Systems Committee) color standards. Very few HDTVs actually achieve above 72% of the NTSC color standards.
