What is the
Difference Between
a Standard Screen
and a Wide Screen?
The type of screen your HDTV has (wide screen or standard screen)
determines how the set-top displays programs on the screen. The picture
format for an HDTV is a combination of aspect ratio and screen resolution
and is different for standard-screen and wide-screen HDTVs.
A standard-screen HDTV has a
4:3 aspect ratio. The screen is 4
units wide for every 3 units tall.
A wide-screen HDTV is one-third
wider than a standard-screen
HDTV. The screen is 16 units
wide for every 9 units tall.
An aspect ratio is the ratio of the width to the height of the TV screen. The
aspect ratios differ because the television industry manufactures both
standard-screen and wide-screen HDTVs to appeal to consumer viewing
preferences.
