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).
