line, you are able to change the setting for the output
aspect ratio. In most cases, the default setting of
ORIGINAL provides the best result, but if the
combination of program material, input source device
capabilities and the adjustments available on your
video display do not provide the desired picture for-
mat, press the
⁄/¤ Navigation Buttons D ©
to experiment with the six available options.
•
ADJUST 1 will stretch a 4:3 letterbox input
vertically so that it fills a 16:9 screen.
•
ADJUST 2 will apply a nonlinear horizontal
s
tretch of a full-screen 4:3 input to a 16:9 screen.
When this option is chosen, objects will appear to
be a bit “fatter,” due to the stretch.
•
ADJUST
3
will process a 2.35:1 image that is
formatted with a 4:3 letterbox and vertically stretch
it to fill a 16:9 screen, but it will also crop the left
and right sides of the image.
•
ADJUST 4 will process a 2.35:1 image that is
formatted with a 4:3 letterbox and vertically stretch
it to fill a 16:9 screen, with nonlinear horizontal
processing so that the full image appears on the
screen. To accomplish this, you will find that objects
on the far left and right sides of the screen may
appear to be “skinnier” than normal.
•
ADJUST 5 will apply a stretch to fit 4:3 full-
screen images to fill a 16:9 screen.
•
ADJUST 6 is an automatic mode that will apply
the processing from
ADJUST 3 to a letterbox
input or
ADJUST 2 to a full-screen 4:3 input.
Once settings are made on the
VIDEO MAIN
menu,
you may either return to the
MASTER
MENU
or proceed to either of the two ADVANCED
CONFIGURATION
setting menus. The
options on those pages are set by your choice on the
SOURCE TYPE line, but you may change one
or more of the settings to customize your video pres-
entation. To return to the
MAIN MENU, press the
⁄/¤ Navigation Buttons D © so that the on-
screen cursor is pointing to
BACK TO MAS-
TER
MENU
and press the OK/Enter Button E
or the Set Button œ .
To change the
settings on the
ADVANCED CONFIGURATION menus, press
the
⁄/¤ Navigation Button D © so that the
on-screen cursor is pointing to
ADVANCED
CONFIG SET
and press the OK/Enter Button
E or the Set Button q. The first page of the
ADVANCED CONFIGURATION menus
(Figure 6) will appear on screen.
Advanced Configuration Settings
The Advanced Configuration Settings may be used to
change the individual items that make up the default
profile for each video input. You may change none,
one or as many of the settings as you wish, to create
the on-screen image that you prefer. As with all of the
video settings, you can't "hurt" anything by experi-
menting with the settings, and while the defaults repre-
s
ent the result of extensive lab testing with a variety of
d
isplay types, input sources and test signals, there is
no "right" or "wrong" setting other than the ones that
look best to you.

f the
ADVANCED CONFIGURATION menus
(Figure 6) are all On/Off settings. On that page, use
the
⁄/¤ Navigation Buttons D © to move
the on-screen cursor next to the line for the setting
you wish to change. Then, press the
‹/› Navigation
Buttons
D © to turn the setting on or off.
Figure 6
These settings are available on PAGE 1 of the
ADVANCED CONFIGURATION menu:
NOISE REDUCTION: When this setting
is turned on, there is a reduction in the video noise
that is often present in analog input sources.
X-COLOR SUPPRESSOR: When this
setting is on, there is a reduction in the cross-color
interference that typically appears in composite
video sources as moiré in finely detailed objects.
DCDi
INTERPOLATION:
DCDi
stands for Directional Correlation De-interlacing, and
it is a Faroudja technology that examines each pixel
for the optimal direction from which to interpolate
the video infor
mation, with regard to local edges
.
This adaptive process prevents the appearance of
staircasing and the jagged edges that are often
visible with other means of de-interlacing
.
FILM MODE DETECT: When this setting
is on, special circuits are used to detect the pres
-
ence of film-originated material so that the original
film-frame sequence may be recovered by weaving
together the appropriate video fields
.
FILM MODE EDIT DETECT: When
this setting is on,
additional processing is applied
when film-based material is detected so that any
disruption in the frame sequence of film-based
material due to video edits or the overlay of video
text over film is compensated for by processing
,
before artifacts such as feathering may appear.
F
LESHTONE NOISE REDUCTION:
When this setting is on, the processing is adapted
to preserve the detail in faces and flesh tones while
reducing noise in the total picture.
COMPONENT VIDEO ENHANCE:
When this setting is on, component video signals
are processed to adjust the high-frequency content
of the signal to offer enhanced depth in the picture,
as well as greater small object detail.
When all settings on this submenu page that require
a
djustment have been made, use the
⁄/¤
Navigation Buttons D © to move the on-
screen cursor next to
PAGE 2 and then press
the
OK/Enter Button E or the Set Button œ
to move to the next page of the ADVANCED
CONFIGURATION
settings, or move the on-
screen cursor next to the
TO VIDEO MAIN
line to return to the VIDEO MAIN menu.

These settings are available on PAGE 2 of the
ADVANCED CONFIGURATION menu
(Figure 7):
TEST VIDEO: The test signals that are
called up on this line are designed for use in factory
setup of the AVR 745’s video processing circuit and
they are not designed for user adjustment of any
controls on your video sources, on your video dis-
play or on the AVR 745 itself. You may bypass this
setting line unless you wish to view the signals, but
remember that they are not designed for any con
-
sumer use.
To view the test signals, with the on-screen cursor
next to the
TEST VIDEO line, press the ‹/›
Navigation Buttons D © to select one of the
test signals described below
, and then press the
OK/Enter Button E or the Set Button œ to
activate the test signal. The test signal will remain on
the screen for the length of time selected in the
ADVANCED
SETTINGS
menu for the
on-screen menus, as explained on page 50. The
four test signals are:
Color Bars: These are a variation of
traditional split-field color bars used to check the
inter
nal settings for luminance/chrominance volt-
age levels with respect to the eight basic colors
.
