Normal
Select Normal to display 4:3 source on 16:9 wide
screen with no scaling and no change to aspect ratio.
With Normal view, vertical black bars will appear on
both sides of the 4:3 image to fill the unused areas of
the wide screen.
Zoom
Select Zoom to display letterboxed 4:3 source which
would otherwise show black bars all around the wide
screen image (such as a 4:3 letterbox DVD). Zoom
uses equal amounts of horizontal and vertical linear
scaling to expand the image to fill the wide screen 16:9
area. There is no change to the aspect ratio.
Full
Select Full to display source material that has been
horizontally compressed during encoding, such as
anamorphic DVDs that are enhanced for 16:9. Full uses
linear scaling to horizontally and vertically stretch the 4:3
source to fit the 16:9 wide screen. This option changes
the aspect ratio.
Enhanced zoom
(ChromeView)
Select Enhanced zoom to display standard 4:3 source
material that has not been horizontally compressed
during encoding. Enhanced zoom uses S3 Graphics’
customized ChromeView non-linear scaling algorithms to
provide optimal horizontal expansion of standard 4:3
source onto the 16:9 wide screen. ChromeView
Enhanced zoom is designed to provide less expansion
in the central image area where viewers usually focus
their attention. This option changes the aspect ratio.
