AYRE DX-5DSD - Manual (Page 44)

Widescreen Displays
Let’s start with a widescreen movie shot in 1.85:1
and viewed on a 1.78:1 widescreen video display. In
this case virtually the entire image can be seen with
no adjustments required. The film is presented in
the same way as in a movie theater.
If we want to now watch a standard movie shot in
1.37:1, With the DX-5
DSD TV Aspect Ratio menu
set to 16:9 Wide we run into a problem. The
narrower picture automatically fills up the screen,
stretching and distorting the image.
This is clearly unacceptable, so instead select 16:9
Wide/Auto in the TV Aspect Ratio On-Screen
Setup Menu. The DX-5
DSD adds black vertical bars
on each side of the picture. These correspond to the
movable curtains used to block part of the screen in
a movie theater and restores the correct geometry.
Standard Displays
When watching a standard (1.37:1) film on a
standard (1.33:1) display, we can see virtually the
full image without adjustments. Again, the film is
presented in the same way as it would be in a movie
theater.
However if we watch a widescreen (1.85:1) film, we
have a new problem. The picture will be distorted as
the wide image is squeezed to fit the standard
display.
