The contrast ratio is defined as a measurement of the ratio between the brightest color (white) and the darkest color (black) that a television can produce. The televisions that offer the best pictures are the ones able to produce the darkest blacks and brightest whites. In most cases, it should be noted that contrast ratio tests are performed by the manufacturer.

Unlike most tests, there is not a standard method for measuring the contrast ratio because each manufacturer has their own way of calculating it. As such, it can be difficult for consumers to compare different models with one another. On the other hand, ANSI (American National Standards Institute) developed a standard test using a checkerboard panel to measure both the white and black simultaneously, but the conditions of the room will play a role in the outcome.

Another method used to measure contrast ratio in HDTV is called the “full on full off method” and it measures the ratio between a pure black and pure white screen. The test will usually produce a higher contrast ratio but it is not a good representation of realistic viewing conditions.

The average consumer does not know what produces the sharpest colors and most would not assume that contrast ratio play such an integral part. The picture on an HDTV is made up of hundreds of thousands of tiny pixels and each of them is arranged to form complete pictures. Models with the best pictures are distinguished by their precision in separating the black pixels from nearby lighter pixels. Many companies are constantly looking to refine their technology to combat what is called “light leakage” in the industry.

Plasma TV’s generally offer the highest contrast ratios when compared to other models such as LCD’s and LED’s. In fact, some plasma TV’s feature contrast ratios as high as 1,000,000 to 1. To compete with plasma LCD and LED manufacturers now feature contrast ratios that are comparable to plasma models.

One thing to remember regarding contrast ratio is that it does not play a role in how well motion is displayed. HDTV delivers an incredibly superb picture so it is important to select a television with a good contrast ratio. After all, one should not waste the features of an HDTV by using an old television with a poor contrast.

For consumers who are regular viewers of HDTV and HD movies, then televisions with high contrast ratios will be the most logical choice for their homes. No matter what type of television, whether it is plasma, LCD or LED, the screen resolution should always be taken into consideration. By considering all the facts regarding contrast ratio and resolution, people can select the right televisions for themselves.

Many of the well known television manufacturers no longer produce televisions that depend on a picture tube technology. Instead, nearly all the older names as well as all of the newer names in television production are producing digital televisions. You will have the choice between plasma television, LCD televisions or LED-LCD televisions.

When shopping for a new digital television there are some things that you should keep in mind to purchase the best television for your home and family.

The most expensive of the digital televisions is the Plasma TV. They do offer several advantages however. The Plasma set is able to produce the contrast that is missing from some of the other digital televisions.

This is because the deep blacks are no problem to produce in a Plasma set. Additionally, colors produced are bright and true to life.

The quick reaction time and lack of shadows makes the sets an excellent choice for people that watch sports or play video games. Sets are available in the 40-65 inch range.

LCD TVs are also available in high definition television, although, just because a set is an LCD set, it is not necessarily a high definition set.

These televisions work best in well lit rooms. They use less energy than a plasma television. The biggest drawback for these televisions it that they have a rather narrow viewing angle for the most part.

This can cause the image to fade out when trying to view from too wide an angle. LCD televisions are available in sizes that range from five inches to sixty-five inches in size.

LED LCD televisions are the newest of technologies available. These televisions offer very slim panels that are not available with other flat panel televisions. Some of the televisions are just over an inch in width.

The sets allow individual back lights to be turned off in order to give darker blacks that are very close to those formerly available only on plasma televisions.

They can also give the same brilliant colors as the plasma televisions. You will find these sets available in sizes from thirty-two to sixty inches. These televisions are some of the most energy efficient models available.

Most people love the picture that is produced by their new TV. Even the LCD sets produce a good enough picture in most cases. However, the sound in many of these televisions lacks the depth that was found in the older sets that had almost two feet of depth to work with for speakers.

Compared to the conventional CRT TV screens, Plasma display devices quickly became recognized for their much improved digital image quality.
Conventional CRT’s use a electron beam to scan the picture from top to bottom at different intervals, which cause the phosphors to light thus creating the image.

Unlike convential CRT screens, Plasma screens have a transistor electrode for every single pixel which more evenly lights the image across the entire surface of the display.
Plasma televisions allow you to see movies in the format the director intended it to be viewed.

With a 16:9 aspect ratio, it was designed to match the natural field of view of the human eye. With billions of colors displayed resulting in smoother picture and detailed shading the picture quality is truly lifelike and amazing.
One important thing to consider when purchasing a Plasma television is what is the preferred resolution of the unit you will be purchasing.

Some common questions asked are whether or not to go with a HDTV (high definition TV) Plasma or the EDTV (Enhanced Definition TV). The HDTV unit is typically more expensive because the Plasma display element is more expensive.

Generally speaking, the HDTV will give you a higher quality image then the EDTV screen, however, the EDTV plasma screen may perform better with lower quality video input signals, such as satellite, regular cable and DVD.

If you have a lot of HDTV channels it would be more beneficial to purchase the HDTV plasma screen.

Either way both plasma screens will produce a high quality viewing experience from any compatible signal.

What about Used Plasma TVs?
If you are considering purchasing a used Plasma television then beware of some older model Plasma televisions that may have screen burn-in damage. Over time if some areas of the screen are used more frequently then others such as a menu bar or other graphical image then this may result in a permanent indentation of the image in the screen.

Over time the image quality will decline and the result is an overall muddy picture. Due to better technology, the newer plasma televisions are less likely to have this problem.
To receive huge discounts on Plasma televisions be sure to do an online search for coupon codes for Plasma televisions.

Most large companies such as Best Buy and Target offer coupon codes online which will give you up to a 10 to 15 percent discount right away on certain Plasma televisions.

You’ve finally decided to purchase a plasma TV. You are so hooked on to this idea that you actually dream of viewing all of your favorite TV programs on the new Plasma TV with its sharp, clarity picture resolution.

How would you find a Plasma TV that works best for your needs and budget?

First, you should decide the dimensions of the television monitor that you want to buy. Note that Plasma TVs start with 32in. and then go up to 63in. The most popular sizes include 32in. , 42in. , 50in. and 61in. It would be a good idea to measure the space where you plan to put your TV. This way, you will get a clear idea about what size to opt for.

Remember another point; the majority of Plasma TVs come with detachable speakers. This means that you should keep some extra space on either side of the space the screen will be so that the speakers can be easily and comfortably allocated.

Once you’ve determined the type and size of sound system you would like, pay some attention to the different mounting options. You can opt for the normal way, which is flat wall mounts. This is preferred because it is one of the cheapest options whereby the Plasma monitor is placed almost flat upon the wall.

One other popular mounting system is the Tilt Wall Mounting system which endows the monitor with the ability to tilt away from the wall up. If this tilting arrangement doesn’t find favor with your sense of taste and style, it is best to avoid it. You can select something simpler like a TV table stand. This would be very ideal for smaller monitors.

There are a number of factors to take into consideration when purchasing your plasma TV. But if you plan with care, you should be able to enjoy your home entertainment center for a long time to come

Another aspect of great importance is installation of your Plasma TV. If you can’t do this, it is best to hire a professional to install the plasma TV. It doesn’t matter who does the Plasma TV installation. As long as you can save time and costs, it is fine. Here are some good tips for you:

To hook up your plasma TV, the simplest and easiest thing to do is go through the owner’s manual, check it for helpful hints or instructions relating to hook up.

When choosing cable connections, opt only for the best quality. A correct length of cable would be required for proper connection. Using a cable that is too short or too long would create difficulties in getting a good signal.

Remember, don’t even think of trying to stretch a short cable. You can add excess cable for essential adjustments. Because power cords do create some degree of interference to getting the broadcast signal, you should make it a point keep the signal cables at a distance from power cables.

With these little tips for installing the plasma TV, go ahead with confidence but do retain the warranty and any rebates or discount offers that come with it.

Plasma TV Widescreen

Plasma TVs are one of this year’s hottest electronic products. Here’s a FAQ that explains what a plasma TV is and where you can get one at the lowest price. What is plasma TV?

A plasma TV is a television with a screen that’s composed of hundreds-of-thousands of tiny gas-filled, colored cells. When electricity passes through the cells they light up and produce a TV picture. What are the benefits of plasma TV?

The benefits of plasma TV are:

• Lifelike picture – Plasma TVs produce a picture that’s so realistic you think you’re watching a scene through a window.
• Slim design – Plasma TVs can be placed virtually anywhere in a room and can even be hung on a wall.
• Flat screen – Plasma TVs have a flat screen so there’s none of the distortion you get with curved screen TVs.
• Large size – Plasma TVs are available in sizes ranging from 37″ up to 84. “
• Widescreen design – Plasma TVs are made in widescreen format so they’re compatible with widescreen DVDs and HDTV.
• Side-angle viewing – Unlike projection TVs, plasma TVs can be watched from any angle without the picture fading.
• Multi-broadcast formats - Plasma TVs are compatible with HDTV, DTV, XGA, SVGA, and VGA broadcast signals. How long do plasma TVs last?

Older plasma TVs had a screen life of 30,000 hours or less. The newer plasma TVs have a screen life of 60,000 hours.

Where can I get a plasma TV at a cheap price?

My advice is to take a trip to your local electronics store or discount store so you can check out plasma TVs in person. Then, when you find a model you like, go online and check out prices at a comparison shopping website. These sites give you prices from various retailers for anything you can think of.

The comparison site I use gives me prices from both online and offline retailers. It also gives me expert product reviews, reviews by consumers who own the products, and even reviews of the stores that carry the products so I know if the store I’m dealing with is reputable and will give me good service.

I recently purchased a flat screen TV through one of the retailers I found on this site that was $150 cheaper than the same TV I found at my local Wal-Mart. I also saved $85 on taxes (you don’t have to pay sales tax on online sites that don’t have a store in your state), and the shipping was free.

I’ve saved thousands of dollars on big-ticket items I’ve purchased online and, thanks to this site’s store ratings, have never had a problem.

Plasma TV

Calculating the correct distance

In creating the environment for your plasma TV, a primary concern is to determine the screen size to match the floor plan or space where the plasma displays.

Plasma monitors are measured diagonally across the screen, like any other television. You can usually choose from the following sizes: 32 “, 40″, 42 “, 46″, 50 “, 61″ or 63 “. Bigger is not always better, and a certain distance must be maintained between the plasma and the viewing area for better viewing.

Sitting too far away diminishes the overall impact. Sitting too close, however, may also present their own problems – like when you get to see the structure of the screen “, ie the points or pixels that make up the plasma screen.

To determine the proper size for the TV, you should also consider the space required to install the unit itself. When recessing a plasma screen, allow at least 3 inches of open space at the top of the unit and adequate ventilation space of at least 2 inches behind it as well. Remember, too, that most plasma displays do not have speakers, so you need to have enough space to connect the speakers.

What you can watch on your plasma TV

You can choose between HDTV (High Definition TV) and EDTV (Enhanced Definition TV) for your choice of plasma display. Which type you prefer depends on the type of material you want to watch the plasma.

ETV is the perfect entry point to digital television with a 16:9 widescreen format and image resolution that is 200% better than today’s analog televisions. On the other hand, HDTV has up to four times the resolution and colors compared to EDTV, offering the best sound and visual experience.

Currently, only a limited number of programs are broadcast in high definition format real (all major networks broadcast HD counterparts to their regular analog broadcast signal). In fact, if you intend to use a plasma HDTV for regular TV programming, you may be surprised to find that regular TV programming may even appear slightly worse, as the big screen exaggerates the flaws in standard TV programs.

DVD images from most DVD titles currently available on the market today also do not fare as well on true HD plasmas. In fact, these DVD images appear better on EDTV plasma units, because the image resolution of a widescreen DVD (nominally 740 x 480) closest to the actual resolution (852 x 480) of the EDTV plasma display.

Why bother with a high-definition TV at all, you may ask? Because HDTV, paired with a source of true HD quality or high, can produce truly stunning images. With a paired with progressive scan DVD player, for example, any of the recently released HD-DVD or Blu-ray next DVD titles (encoded in true HD format), your plasma HDTV can come to spectacular life and bring out the unmatched image quality.

And as television programming becomes more available in high definition with the appearance of the FCC deadline for switching to all-digital broadcasting, HDTV plasma televisions will have more TV content to display. One thing is certain: HDTV will not be obsolete anytime in the next few years.

Flatscreen

Specifications: When comparing plasma TV sets, it is important to know what to look for to make sense of the specifications provided to you. Below is a quick rundown on the specifications required that you need to consider before taking the decision to purchase all-important.

Resolution: Resolution is a determining factor in choosing a plasma TV. Do you want HDTV or EDTV? HDTV, with resolution of at least 1024 x 720 is the best sound and visual experience, but what is available for viewing on HD is currently restricted to a few HD channels on cable, and the emerging – and necessarily few – travel DVD HD-DVD and Blu-ray formats.

Moreover, most currently available DVDs actually play better when viewed on EDTV, because the image resolution of a widescreen DVD (nominally 740 x 480) closest to the actual resolution (852 x 480) of the EDTV plasma display. Choose the type of plasma TV you want, so it is an issue that should be considered along with the type of content frequently watch or will be watching on your plasma.

Inputs: a plasma TV should work with any existing video component with standard A / V, S-Video, or component video outputs. In addition, most plasma TVs have DVI or HDMI connections for use with HD sources. Some plasma TVs also have VGA input connections that allow them to be used as a PC monitor.

At a minimum, look for the following specifications in a plasma connection: DVI-I or DVI-D, Component, Composite and RCA or S-Video. Consider the current set-up component – such as your satellite system, cable, DVD, stereo, and external components – and see what kind of inputs or connectors they use.

Tuner: Check your plasma to see if it is HD-ready or HD-integrated. A plasma TV HD-ready is essentially a monitor that needs an external tuner source before it can function as a TV. An HD-integrated panel has a tuner in the set and is ready for use.

If you get your HDTV programming via cable or satellite, rather than over-the-air, you may not need a tuner at all, as you will be using the set-top boxes provided by cable / satellite service to receive HDTV programming. Check with your cable or satellite providers for more details.

Some cable or satellite companies do away with set-top boxes and provide their subscribers with cable cards instead. Check with your cable / satellite provider if they provide cable cards and cable type of card they offer, and then check the specification on the plasma slots for cable cards.

Contrast: Contrast is the measure of the variation between the white and the darkest image. This is an important specification, since plasma TVs with a contrast ratio of low dark images will look muddy and gray while making light images look washed out. A good measure of the contrast ratio is 1000:1 or higher. Anything less than 1,000:1 – especially in a game that is 42 “or larger – can not provide an optimal viewing experience.

Brightness: Without sufficient brightness, your image will look muddy and soft – even in a dark room. Viewing distance, screen size, and ambient light will also affect the need for greater ability to shine. The brightness rating of 550 cd/m2 listed or higher is good, but not get stuck with the number of technicians listed. Instead, make sure that the screen is bright enough for your needs as you conduct your own visual inspection.

Panel Life: Look for a minimum of 60,000 hours of panel life in their specifications of plasma. This is the assessment of how long would it take before your panel has half the brightness compared to when it was new. The 60,000-hour spec translates to approximately 20 years of showing in 8 hours a day. (This approximation may vary depending on the source and type of content, settings, environment and use of your plasma TV.)

Anti-burn-in/Pixel Shift: burn-in “refers to the remains burned to the screen after a static image was left in plasma for a long period of time. To minimize or prevent burn-in, check that the panel uses plasma burn-in protection, such as settings for power management, full-time or displacement of pixel (vertical and horizontal) technologies, or automatic screensaver functions.

Speakers: If you plan to use an external surround sound system, you will not have audio speakers, but most plasma TV sets include speakers that rated anywhere 7-12 Watts Pre-amp – it is much better than that of conventional TVs and sufficient for most of the vision. Check the specifications of the plasma to see if it comes with speakers and the speakers are removable.

Universal Remote: A universal remote can take the place of having a remote control so that all components of your TV system, such as DVD player, audio, cable / satellite, etc. If you are thinking of buying one universal remote, check to see if it is supported by the plasma set of your choice to ensure that the plasma devices universal remote.

Power Consumption: Power consumption for plasmas range from 240 watts over 500 watts, If you are concerned about the amount of energy a plasma can be used, check its specifications to determine power consumption.

Units tend to have higher power requirements with increasing screen. A good rule of thumb is to compare similar sized units, as well as units with high power tend to use inferior components as a rule.

Installing Plasma TV Wall Mounts to enjoy the features and big screen of your Plasma TV, it is very important to make sure that the mounting of your TV on the wall is properly made. If you are not hiring a professional and confident that you can fix it, the following are the 4 steps to install tv wall mounts for your flat screen Plasma TV.

1. Find studs in the wall. Once you select the suitable tv wall mount and the exact location of the tv mount on the wall, you need to find the studs in that wall location. It is very important that the mount is securely fixed to a stud. Find the center of the stud for the best results. You can easily find the studs in the wall using a stud finder.
2. Drill into the wall. Mark the center of the stud with pencil on the wall. Ensure the mounting bracket locations are level and that the height is appropriate by using a cardboard of the size of the flat panel TV. Once you are sure that the correct markings are made, drill in to the markings on the studs. Make sure two or three times before drilling into the wall for the correct levels.
3. Attach the mount and drill for the cables. After exactly drilling into the studs, attach the mount to the wall with the screws. Double check to ensure that the tv wall mount is level. Drill a hole behind the bracket to hide the wiring. Once it is done pull the cables through the wall. If you don’t want to drill again, use tapes and other tools to hide the cables.
4. Attach the Flat TV. Once you are done with the wiring, the last step is to fix the TV set to the tv wall mount. As the flat panel TV is often heavy, you need another person to hold it at least for few minutes. It’s a good idea to attach all of the cables to the TV before fixing it to the mount. Otherwise, it is difficult to connect the cords with insufficient space between the wall and the TV. You will not have this problem if you have swivel & tilt TV wall mount.

Once you finish the above step, you are successfully done with fixing the tv wall mount for your flat screen plasma TV. Enjoy the wall mounted flat screen TV that adds beauty and elegance to your living room and gives you a great entertainment experience.
