When you go for a Plasma TV, you should know how native resolution of a Plasma TV counts most in displaying the resolution of the original input signal that it receives.

Based on the native pixels that a Plasma TV has, it can be classified into a HDTV or HDTV Ready which actually refer to the capabilities of a Plasma TV to display HDTV resolutions. Any resolution that ranges between 720p and 1080p is called HDTV resolution. A TV that comes with a native resolution of 480p or below can not display the HDTV resolutions with a desirable picture quality

Generally most high end plasma TVs come with native resolution of 1024×768 pixels which means the screen will have 768 lines vertically from top to bottom. There is another higher resolution 1080i or 1920×1080 pixels which can show images of the same resolution without any scaling of the pictures to fit them on their screen. While Plasma TVs of native resolution 1080i are not so many in the market and they are generally much more expensive presently, the Plasma TV makers come with plasma TVs with lesser resolution and even some of the cheaper Plasma TV are incapable of showing pictures of resolution above 480p.

When you buy a Plasma TV with 720p resolution or higher, and you want it to display input signals of 1080i, the original pixels of the input have to be scaled down so that the image can be accommodated on the screen. For example, your plasma TV has a native resolution of 1024×768 pixels but needs to show images of 1080i resolution, the original pixels of the input have to be scaled down to match the native resolution of your plasma TV. This will prevent you from viewing the resolution of the original input signal.

It is highly recommended that you choose your Plasma TV after studying its native resolution, especially when you receive HDTV broadcast via your cable television network. Plasma TVs with lesser resolution of 480p are incapable of showing HDTV pictures and they are suitable for viewing EDTV signals.

What is HDTV?
High Definition TV broadcasting is still in its infancy stage in the UK. This new way of TV broadcasting had its inception in the UK in March last year. Some of the popular TV services in the UK like Sky, BBC and Televwest have launched HDTV broad casting and offer HDTV programmes which are gaining popularity and massing up large number of viewer-ship in the UK.

The main features of HD broadcasting are their superb picture quality and outstanding sound effects which are indeed beyond the scope of any SDTV broadcast. So, what makes HDTV so popular, so distinguishing while the standard definition television is gradually losing its prominence in the present world?

To begin with, HD has a better resolution. The higher the resolution the sharper the images will be. The traditional analogue TV has a resolution of 625i or 625 interlaced lines as opposed to 720p or 720 progressive lines. It is for this reason that HD resolution cannot be supported by a standard CRT TV as its native resolution is much lower than the standard HDTV resolution.

Advantages of HDTV:

• Wide aspect ratio offers you cinema-like experience
• Images possess unrivalled clarity, smoothness and larger-than-life quality.
• Pictures exhibit great depth and life-like quality
• Images are much sharper due to the high resolution.
• Wide range of true-to-life colours
• 3-D Dolby Digital surround system

High Definition TV requires flat panel screen like plasma TV or LCD. Especially Plasma TVs have some unique features like larger screen size, the widest range of black levels and extra-ordinary contrast which take you to new levels of TV viewing.

When you go for a Plasma TV, it is a good idea to check whether it is a HDTV Ready as it makes a huge difference. To make things clear, a HDTV compatible plasma TV can receive video signals including SDTV from a HDTV broadcast but cannot produce the outstanding picture quality like a HDTV Ready Plasma TV. However, a genuine HDTV Ready Plasma TV certified by EICTA offers you true high-definition television experience.

More on The World’s first 42 inches Plasma TV with full HDTV features

High Definition Television is the new buzzword in the world of television. More often, the word HDTV is in a sense analogous to higher resolution. As a result, we indulge in a simple calculation: the greater the resolution, the better the picture quality will be. As a result, we go for flat panels which have high native resolution like 720p or 1080p. But, is the resolution only one criteria for judging the picture quality of a display? It is true that the higher resolution ensures sharper pictures. However, there are also other features like colour reproduction, brightness and contrast which are equally, may be, more important than resolution as the over-all picture quality is the hybrid of all these features.

While you go through plasma reviews, the specification of the TV often provides you with essential information like resolution, contrast ratio, response time etc. If you are already familiar with these terms, you may often find yourself in a better position to choose the best Plasma TV to suit your taste. It is also a good idea to navigate through the features listed in the review. Double check, whether the plasma TV which lures your attention with its stylish design and excellent specs, has been provided with anti-glare technology as the plasma screens have a natural tendency to reflect light in ambient conditions. Especially, when you plan to install your plasma tv in a bright room, this feature is often useful.

Well, how to evaluate the performance of a plasma TV? As a thumb of rule, branded Plasma TVs often render great pictures. However there is a maze of specification which may often bewilder you if you are not so familiar with. Fortunately, it is not be- all and end-all.
You may still become a better judge of plasma TV than a reviewer using these simple techniques:

• Check how the colours look on the screen. Do they look natural and accurate? How is the colour saturation? How do the nearest hues appear distinct?

• Next important consideration is the black levels achieved by the TV. Play a DVD and watch dark scenes on the screen. You should be able to see the darkest objects without graying. It is a good idea to test this feature in a little dark room instead of bright room.

• Test the sharpness the pictures by reducing the brightness settings as the maximum brightness may often hide the flaws. Reducing the brightness and contrast to 50 % of their original settings often help you to judge the picture quality.

• Most Plasma TVs boast of their HDTV capabilities. It is wise to put them under a test before you invest money. If the retailers cannot provide HDTV broadcast, a Blue ray disc or a DVD often makes best video material to test the performance of the TV.

• Be familiarized with the remote and meddle with all the pre-sets which modify how the images look on the screen. Some of the Plasma TVs have come up with a myriad of useful presets which may add greater value to your money
