The clarity of the images is such that it can match the effect of a theatre hall.

The luminosity of the images, in an original HDTV is twice that of normal TV.

The screen is minimum 20% wider, both in vertical and horizontal dimensions.

With a high definition TV set, you may have optimum viewing pleasure due to its latest digital technology. The images displayed on the screen have crystal clarity, wider screen size, DVD quality sound effects, all this at a much superior resolution than your previous old modeled television set. A HDTV has brought a revolution in the television world. Some of the most common questions that are put forth regarding a HDTV are as follows:

What exactly is a resolution line number?

The encoded numbers with resolution of 720p, 1080p or 1080i are required for programming of a high definition TV. The numbers essentially symbolize the line quantities fixed inside the signal. The letter I indicates interlaced picture displays and p stands for progressive picture display.

Do lines matter?

On a television screen, the image displayed on the screen depends on the amount of lines for quality and perfection. Same way as a dpi is utilized for printing images of a digital photo. Old television sets just had around 480 lines, but modern TV sets like HDTV has double the amount of lines, and that’s the reason behind the terrific clarity and picture quality. The television models used by your mom and dad had probably not more than 480 lines on the visible display.

Which resolution is better, interlaced or progressive?

Actually, the lines on the screen are more important than the scan type, a progressive scan is more common and popular. A progressive scan gives faster display per second. And the 1080p is more superior to 720p or 1080i.

Is your Television set HD compatible?

There are very few TV sets, which have the capacity to display HD content in a normal 480p type of resolution. Mostly only a high definition television set can exhibit high definition content in the HD resolution of around 960 lines.

Does a HDTV have all the features for watching HD content? It is not necessary that a HDTV will give you HD content. You have to buy many supporting accessories like HD tuner, set top box, and subscribing for an HD package. Only then HD signals will be permitted in your TV sets.
