Rear Projection Tv Rating

One of the trendiest items of modern living is to own a rear projection, flat panel TV. With a wide variety of brands available in HDTV, to make an informed choice is indeed a daunting task. Are you going for those ones with plasma and LCD screens which are only a few inches thick and the TVs lightweight ? Which one would be most suitable for your room ? Plasma or LCD flat screen TVs ? Here's what you should know before you buy.

In the rear projection TV category, in terms of looks, both LCD and plasma screens resemble each other, though the technologies involved differ -as do their individual strengths and weaknesses.

Before you buy any one of the two it is important to learn what an aspect ratio is. It is the ratio of screen width to screen height. Practically all HDTV plasma come with wide-screen designs, which means that they have a 16:9 aspect ratio. This ratio is standard for all rear projection HDTVs. This ratio makes these televisions more rectangular in shape than vertical, verging on being square with 4:3 display screens. HDTV with plasma screens may range from 42 inches diagonal measurement to 61 inches. There are also brands available with 37 inches size screen while some are as big s 103 inches. Prices of HDTV plasma could be anywhere between $1500 to $15000. While the traditional TVs have a 4:3 ration, wide screen rear projection TVs have a 16:9 ratio.

Price is an important factor when it comes to quality, with HDTV plasma. A 42-inch HDTV plasma which is available for $1400 can not assure the same quality of output which you can get from a $2500 plasma screen HDTV of the same size. The lower priced models have poorer contrast and lack in displaying minute details. Even in terms of any upward conversion which it might have to do with standard TV programs or DVDs - cheaper plasma HDTVs may display softer, rougher pictures.

You will perceive the inadequacies of HDTV plasma when you want to see deep blacks and grades of dark gray. It can not match the quality even a good CRT set can reproduce. This aspect has been looked into and improvements included in recent models, by which you will not even be able to notice the differences. HDTV plasma, in terms of technology use phosphor to create light - this makes them susceptible to burn-ins.

Take the example of a static image being left on the screen for a long time, like a channel logo or a corporate banner. You might have noticed that the image does not immediately disappear if you switch channels. This is particularly relevant, if a HDTV plasma is subjected to prolong use for standard TV programs or for playing games, where there are often static backgrounds.
