Widescreen TV
Note:  If your TV is 
connected using an 
HDMI cable, you 
may not see a 
choice of settings. Yes (16:9)
(No 4:3) Yes tells the system that widescreen (16:9) is the TV format.
No tells the system that 4:3 is the TV format. 
For a TV connected using a Composit
e, S-Video, or Component cable, 
selecting No also makes availabl e the DVD Image option (below).
Note:  If you are not sure what type of cable  is used to connect your TV, check the 
Video Connector indicator, which is explained on page 51.
DVD Image

is NOT available 
UNLESS you have 
selected No in the 
Widescreen TV 
option (above) for 
your TV connected 
using a Composite, 
S-Video, or 
Component cable 
(not HDMI). Modified 
(Original) For a TV connected using an HDMI cable:
 
Modified allows the Bose® system to automatically provide the resolution that is 
preferred for your TV (usually 720 or 108 0), so the image fills the screen. You can 
change this video resolution in the Settings menu. 
Original tells the Bose
® system to keep the image in the original DVD format (in 
480 or 576 resolution), regardless of how it fills the screen. No change can be 
made to this video resolution in the Settings menu.
(Some TVs determine automatically how to  fill the screen, overriding any choice.)
For a TV connected using non-HDMI cable:
Modified allows the Bose system to ad just the images on some widescreen DVDs 
to fill a 4:3 TV screen. This is done by  removing the black bars on top and bottom 
and by cropping the sides of the image.  (Many DVD images, even widescreen, will 
still appear with black bars on top and bottom.)
Original tells the Bose system to keep the image in the original format of the DVD. 
A widescreen
 DVD image will have black bars on top and bottom.
