So you've been thinking about buying a TV. LCD or Plasma are a great choice to start. But first, there's some things you need to know before you make your decision. Both LCD's and Plasma's are considered flat panel TV's because of the excellent viewing angles they provide along with there slim thin design, with most flat panels being anywhere from 3 inches plus depth. These flat panels are more improved than your older tube televisions or floor model console's because of the incredible picture enhancements including high definition ( a digital broadcasting system with greater resolution than traditional systems such as NTSC, SECAM, and PAL), as well as many other features in the newer and select model flat panels. Some of these flat panels might include neat features such as PC compatibility, which allows you to use your television as your monitor when hooking up to your computer. Built-in-DVD player's which may offer much convience; but don't be surprised if you aren't finding this feature in a lot of models. Most manufactures aren't making them but in select TV models because of the effects the DVD player/TV has on one another in terms of defect and difficulties having more chances of ruining the entire set. You might also notice a change in screen appearance from the traditional full screen to now more widescreen built sets in most flat panels. Some additional words and terms to look for when deciding which TV set fits your desires are Resolution, Contrast Ratio, and frame rate.
The Resolution are the scanning lines. It's simple, the more scanning lines means the more pixels, more details, and a better picture. 720p/1080i and 1080p are common resolutions found in HDTV. The (p) stands for progressive and the (i) stands for interlace. Progressive usually giving you the better picture. 720p/1080i were more common in the first HDTV and flat panels under 40 inches which provided a high definition picture. Since then 1080p has came out and delivers almost twice the high def. picture if your television carries the 1080p signal. You can definitely say that 1080p is the future of television. The 1080p signal or resolution itself is only available in delivering that twice high definition picture quality, making you feel as if your actually there, when your watching your movies with a special DVD player called Blu ray or HD DVD. The 1080p signal isn't offered through cable or satellite companies quite yet, but they have been working towards getting it out there in the next few years to come, so when it comes out, just like HD was released, you'll here about 1080p. So this means you'll be able to watch your news, sports, and regular broadcast channels in that realistic 1080p quality. So why should you buy a 1080p vs. 720p/1080i TV now if you can only see your movies in 1080p for right now. Well, it all depends. As a home entertainment specialist, I've learned that everyone has specific needs and desires, and no two people are the same. If your someone who doesn't watch alot of TV, or the quality that HD delivers is satisfying enough for you; or if your someone who doesn't mind buying another TV in the near future once 1080p is released, then 720p/1080i will probably be suitable for you. If your looking for the ultimate HD experience, or you want to stay a step of technology and not have to worry about having to buy another TV just to get the 1080p signal through your television set once 1080p is released through cable or satelite. Then 1080p is the perfect choice for you.
The contrast ratio is the ratio of luminance between the brightest "white" and the darkest "black" that can be produced on a display. The higher the contrast, the sharper and crisper the picture. Contrast ratio between different brand manufactures aren't comparable. The only time contrast is comparible is if you are comparing two or more contrasts of the same brand. Frame rate is another important term to look for when determining which TV is best for you. Frame rate is the measurement of the frequency (rate) at which an imaging device produces unique consecutive images called frames. 60p is a progressive format used in high-end HDTV systems. In the newest model televisions you will now see even 120hz(hertz) or higher. Twice the frame rate of some of the past HDTV models. The higher frame rate gives you a more better picture and reduces pixelization you might have noticed when you were watching action, or fast moving objects on a HDTV set with less hertz.
