まったく知識がないので教えてください。

今、ＢＯＸＩＮＧ　ＷＥＥＫで家電とかもセールしていて、液晶テレビもかなり安くなってますよね？
そこで、買おうかと思っているのですが、なにしろ知識がまったくナイために値段と大きさ以外のどこを見て選べばいいのかわかりません。
よく聞くＬＣＤっていうのも、あんまり意味がわかっていないし、選ぶテレビによってはＳＨＡＷの契約もデジタルにしないといけなかったりするんですよね？
デジタルで契約しなくても、キレイにみれた方がうれしいんですけどね。
オススメのとかありますか？

ちなみに、狙っているのはSONYとかSAMSUNGの３２型、５００〜６００ドルくらいのテレビです。

旧型ＴＶとＬＣＤＴＶは電波シグナルが違います。
ＬＣＤＴＶは旧型電波のシグナルをよみとらないので綺麗にうつらないそうです。
いつか将来、すべてデジタル放送になるとは思いますが。

＄５００〜６００のＬＣＤＴＶは１０８０ピクセルでない品が多いです。ブルーレイを使用したい人は１０８０ピクセルＴＶを使ったほうが、より活用できます。　　 　

Liquid-crystal display televisions (LCD TV) are television sets that use LCD technology to produce images. Benefits of LCD technology include lower weight and reduced power requirements when compared to other display types. Often, LCD television screens can also be used as computer monitors.

Moving pictures on a CRT TV do not exhibit any sort of "ghosting" because the CRT’s phosphor, charged by the strike of electrons, emits most of the light in a very short time, under 1 ms, compared with the refresh period of e.g. 20 ms (for 50 fps video). In LCDs, each pixel emits light of set intensity for a full period of 20 ms (in this example), plus the time it takes for it to switch to the next state, typically 12 to 25 ms.

The second time (called the "response time") can be shortened by the panel design (for black-to-white transitions), and by using the technique called overdriving (for black-to-grey and grey-to-grey transitions); however this only can go down to as short as the refresh period.

This is usually enough for watching film-based material, where the refresh period is so long (1/24 s, or nearly 42 ms), and jitter is so strong on moving objects that film producers actually almost always try to keep object of interest immobile in the film’s frame.

Video material, shot at 50 or 60 frames a second, actually tries to capture the motion. When the eye of a viewer tracks a moving object in video, it doesn’t jump to its next predicted position on the screen with every refresh cycle, but it moves smoothly; thus the TV must display the moving object in "correct" places for as long as possible, and erase it from outdated places as quickly as possible. LCD televisions are also a good component for video games.

Although ghosting was a problem when LCD TVs were newer, the manufacturers have been able to shorten response time to 2ms on many computer monitors and around an average of 8 ms for TVs.

There are two emerging techniques to solve this problem. First, the backlight of the LCD panel may be fired during a shorter period of time than the refresh period, preferably as short as possible, and preferably when the pixel has already settled to the intended brightness. This technique resurrects the flicker problem of the CRTs, because the eye is able to sense flicker at the typical 50 or 60 Hz refresh rates.

Another approach is to double the refresh rate of the LCD panel, and reconstruct the intermediate frames using various motion compensation techniques, extensively tested on high-end "100 Hz" CRT televisions in Europe.

LCD technology is based on manipulation of polarized light. Two thin polarizing sheets are laminated to two glass substrates containing a thin layer of liquid-crystal. A regular 2-dimensional grid of electrodes allows each pixel in the array to be selected and activated individually. Several LCD technologies are used for the realization of large format television screens (e.g. TN, IPS, PVA, FFS), all in combination with active-matrix addressing.

It had been widely believed that LCD technology was suited only to smaller sized flat-panel televisions at sizes of 40" or smaller. Early LCDs could not compete with plasma technology for screens larger than this because plasma held the edge in cost and performance. However, LCD TVs can now offer acceptable performance in larger sizes. 　

私も買いましたｂｏｘｉｎｇ　ｄａｙに３２インチのＬＣＤＴＶ。
アナログとデジタルの両方のチューナーが備わっているので大丈夫です。どの機種でも。うちはアナログケーブルですが。信じられないくらいきれいにうつる。３２インチまでだったら７２０ｐでも１０８０ｐでもちがいは解らないくらいだと店員さんは言っていました。ｓｏｎｙ３２インチＢＲＡＶＩＡいいんじゃないんですか？
＄４９９ｓｅａｒｓ、ｓｏｎｙ　ｓｔｏｒｅ、ｂｅｓｔ　ｂｕｙその他で同じ値段で売ってます。わたしはｔｏｓｈｉｂａの３２インチを買いました。ｓｏｎｙはすぐ持ち帰れる在庫がなかったので。 　

みなさんありがとうございます。
参考にさせていただきます。 　

私もソニーかパナノニックが欲しいのですが、夫いわく、液晶テレビを買っても他に＄６００ぐらいのボックス？を買わなければ見れないと言われました。もう少し、待てと言われました。
