What Makes the HD Viewing Experience So Special?

To videophiles, the technology is what makes HDTV so special. But to a regular viewer, there are basically three things that make HDTV (espe- cially, your LCOS HDTV) the ultimate viewing experience:

•resolution

•aspect ratio

•digital picture and sound

Resolution:

The crisp, life-like picture people rave about when experiencing true HDTV is due to the resolution this technology provides.

A regular television (called standard definition) displays about 200,000 pixels. A pixel (which stands for picture element) is a small dot. The picture you see on your TV is composed of these dots. HDTV displays 1 million to 2 million pixels (up to 10 times the resolution of the picture on a regular TV).

Aspect Ratio

Aspect ratio is nothing more than the width and height of the picture. Regular TVs use a 4 x 3 (also written 4:3) aspect ratio, which means the picture is a little wider than it is tall (a screen that is 20 inches wide is about 15 inches tall).
