Is your Plasma TV HDTV-enabled?
July 10, 2007
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.
