The Low Down on LCD TV’s
When you buy an LCD TV today, you are probably going to want to answer some questions beforehand. Because it is such a big investment, you need to understand what you are looking at. How long will these things last? Is it really worth spending all of that money? These are important concerns, and you need to address them before you open up the wallet.
Any review of LCD TVs can not be complete unless you talk about their durability. These are machines that are highly durable, as long as you take good care of them. They don’t burn out quickly and they hold their good form for years. Likewise, you will need to discuss the size that you want. LCD televisions come in a big range of sizes. They are anywhere from 17 inches to 70 inches on today’s market.
Lots of people will talk size when they look at LCD televisions, but the smart buyers will be talking resolution, too. Many of the best LCD TV’s out there today are offering 1366 X 768 resolution. That is tops in the TV market today and it is absolutely necessary. This is solid for the consumers who love their HD television, and it’s as good as the technology gets today.
When people discuss the difference between a plasma TV and some of the best LCD TV’s on the market, they will always talk about burn-in. This is one of the problems with plasma televisions, in that past images are left in the display. This is especially true with numbers on the screen, and it is not a problem if you have an LCD TV.
One of the buzzwords for the television industry today is 1080p. People want to know if their new LCD television is going to feature 1080p display, and it really is important. If you want to be able to enjoy HD DVDs or any of the new technology, then you will have to have a television to match. Some of the best LCD televisions today are providing this.
Another chief concern for any consumer has to be how long the televisions will last. We mentioned their durability, but what does this really mean. How long can you expect to own an LCD TV? That is a question that is better answered on an individual basis, but you can reasonably expect LCD TVs to hold their form for five years. In some cases, they can last up to ten years.
When you go out looking for LCD televisions, you have to be sure to think about what sort of new technologies are on the way. Right now, the newest thing is technology to avoid blurring. The new LCD TV’s are making it so that you don’t have to watch blurry action shots and sports fans are especially enjoying this new change.
There is a wealth of LCD TVs out on the market today and they are getting better. The vast number of features and the incredible display possibilities make it a must for any person who wants to enjoy television. An LCD TV is a good investment on many fronts.

Wading Through Technology – HDTV Televisions, Which One is Best For You?
There are several to choose from. The main three HDTV types are LCD, plasma, and the new LED, all thin enough to hang on your wall.
HDTV LCD televisions provide a wider and sharper image that rivals DVD’s. HDTV televisions offers about twice as many “lines” of resolution and better quality, digitally encrypted sound to enhance the viewing experience.
Digital HDTV’s can provide sharper, clearer pictures and sound with very little interference or other imperfections. Of perhaps greater importance, digital television sets will potentially be able to send, store, and manipulate images as well as receive them, thereby merging the functions of the television set and the computer.
Unlike the rear projection TVs of the recent past, the new DLP TVs are thinner as well, but not yet to the point where you can hang them on your wall. But DLP has a price advantage, which means you can get a bigger screen for less money!
You may also want to compare Plasma TV and LCD TV as it is this comparison that is putting more pressure on DLP manufacturers. With DLP, you can also get a front-projection system, which requires a dedicated screen. This is the preferred method of many home-theater buffs, since it allows for a flawless picture and a much larger screen, but it’s not the best set-up for most living rooms.
An HDTV LCD television is a flat screen and so they look very sleek and cool in any room and another advantage is that a flat screen LCD television will require much less space than “Grandma and Grandpa’s” old bulky televisions. The Liquid Crystal Display technology that is behind the LCD televisions has come a long way in recent years, it has been around for a very long time but only recently has it been able to produce the kind of quality needed for a modern television.
LCD TVs vary in size, but larger sizes have been limited due to manufacturing costs and are now coming down. We are now seeing manufacturers like Vizio, Samsung and Sony producing larger and larger screens.
Sales of Plasma Televisions have not grown as much as LCD Televisions sales, partly because plasma screens have a shorter life span and use more energy. In terms of quality, LCD, Flat Plasma TV, and DLP all come in a variety of high-def resolutions, and each side will argue that they offer the best experience. That’s a much longer discussion, but we’ll just say that each one has their strengths and a few weaknesses depending on the type of environment and content you like to watch.

LCD Televisions – Things You Need to Know Before You Buy
So what should you know before you make your new purchase? Here are some helpful tips to hopefully make your preliminary decisions a little easier.
Size
LCD TV’s are available in such a vast array of sizes. You can purchase as small as 10″, and then move up the range from 32″, 37″, 42″, all the way up to 108″. The decision can be difficult with so many options, however, begin by considering the viewing distance from the prospective television. How far away do you plan on sitting from your new LCD TV? Obviously, you do not want to buy the 52″ TV if you are only 4 feet away. Optimally, for LCD TV’s of 42″, plan to be about 10 feet away, where as an LCD TV of over 60″ should be viewed at over 15 feet away. In sum, do not get in over your head and buy a large TV without having the proper space to view it.
Resolution
Resolution may be expressed as 720p, 1080p, 1080i, 1024×768, etc. These numbers represent the vertical and horizontal lines that make up the picture quality on the screen. The most advanced and future-ready resolution is 1080p, which stands for 1080 pixels (or vertical lines) with progressive scanning. This is better than 1080i, as the “i” represents “interlaced”. Interlaced simply uses the previous technology of updating a picture every other line beginning with the odd numbered pixels, and then the even. Progressive scanning is constantly refreshing every pixel all of the time.
Refresh Rate
In addition to either progressive or interlaced scanning, companies such as Samsung, Panasonic, and Sony offer multiple speeds in which those pixels are refreshed. With a higher refresh rate, comes better clarity, less interruption of high action scenes. The most common refresh rate is between 60-120 Hz, however, 200 Hz has reached some markets. Smaller TV’s may not show much difference with higher resolution and refresh rates, but on the contrary, larger TV’s demonstrate rather big differences.
Contrast Ratio
Contrast Ratio is described in terms of 700:1, or 25,000:1. It is simply a ratio of how many steps it takes in shades of gray to go from black to white and back again. Some brands offer what they call “Dynamic Contrast Ratio” in which is not a true description of the TV’s color capabilities. With a dynamic contrast ratio TV, it will lower the back light in darker scenes to darken pictures. In short, an LCD television with a higher contrast ratio will be able to deliver greater color and picture quality.
Overall, when deciding on a TV, begin with determining the size that meets the needs of the viewing room. From there, you can decide on the importance of the resolution, refresh rate, and contrast ratio.
