Advanced Functions
Plasma and CRT monitors may suffer from “burn-in” when the same image, such
as the horizontal or vertical bars, is left on screen for a long period of time. Adjust
the picture so that it fills the display’s screen. Highlight this setting and press the OK
Button. Each press of the Up/Down buttons changes the setting. Press the OK button
when the desired setting appears in the display box at the lower right corner of the
video screen.
• Auto Fit: The AVR automatically adjusts the image, as required, to fit the display’s
capabilities.
• Height Fit: Adjusts the image to eliminate any bars above or below it. Bars may
remain at the sides.
• Width Fit: Adjusts the image to eliminate any bars on the sides. Bars may remain
above and below the image.
• Zoom 1x: Displays the image as received from the source. If the image is in the
4:3 aspect ratio, on widescreen displays the pillarbox format may be used. If the
image is in the 16:9 aspect ratio, on full-screen (4:3) displays the letterbox format
may be used.
• Zoom 2x and Zoom 3x: Stretches the image evenly to fill the screen completely. The
outer portions of the image may be cropped.
Experiment with this setting until you find a pleasing display format for each program.
Overscan: For historical reasons, there has been a convention among video
broadcasters to reserve an area around the border of a video frame, called
“overscan,” that may be viewed on newer high-definition displays, although it was
not visible on older analog television sets. However, since not all displays are capable
of showing this portion of the frame, directors avoid placing important information
in that area.
If your video display is capable of displaying the overscan area, set Overscan to On
to prevent the display from showing a black border around the image, which could
cause unwanted “burn-in” on some plasma and CRT displays. The AVR turns this
setting off by default when the source device is connected to one of the HDMI input
connectors.
Advanced Video Settings: Select this to display the Advanced Video Modes
submenu. This submenu is not accessible when the Video Mode setting is set to Off.

Noise Reduction: Adjust this setting to Low, Medium or High to filter out signal noise.
MPEG Noise Reduction: This setting is designed to address two specific types
of video distortion: mosquito noise and blocking artifacts. If you see haziness or
shimmering around the edges of objects or the scrolling credits in a film, or if the
image appears to “pixelate” into blocks, change the MPEG Noise Reduction setting
from Off to Low, Medium or High.
Cross Color Suppressor: Turn this setting on to remove cross color artifacts, which
can occur when high-frequency luminance (brightness) signals are misinterpreted as
chrominance (color) signals, causing unwanted flickering, flashing colors or rainbow
patterns. This setting is not available when you are using HDMI sources or when no
video signal is present.
Flesh Tone Enhancement: Turn this setting on to enhance the flesh tone of peoples’
skin. (On many TVs this enhancement will be subtle.)
Black Level: This setting is effective only when the AVR’s Composite Video Monitor
Out connection is being used. Set the Black Level to On for a full black-level setting
that provides the full dynamic range of black as presented on most DVDs. When set
to Off, the Black Level setting complies with NTSC standards for video and may be
more appropriate when your video display has limited video-processing capability.
Deinterlacing: Analog video in the NTSC format is interlaced. That is, each refresh of
the television screen displays only half the pixels in a frame, alternating between all
of the even rows of pixels and all of the odd rows. Modern video displays are capable
of displaying the complete frame all at once by progressively scanning all of the
rows of pixels from top to bottom. For optimal viewing on a progressive-scan display
(e.g., most flat-panel displays), the video images must be deinterlaced. When you are
viewing images via the Composite Video Monitor Out connection, any time the AVR’s
video output resolution is 480i, this setting may be turned off.
Film Mode Detect: This setting is accessible only when the Deinterlacing setting
is turned on. It compensates for the different frame rates in which film and video
are shot. Film is shot at a rate of 24 frames per second (progressive scan), while
video is shot at slightly less than 60 frames per second (interlaced). The AVR is able
to detect whether the program was originally shot on film and transferred to video
(e.g., to create a DVD), and will compensate appropriately for any authoring errors in
the conversion. Select a setting of 3:2 (for NTSC materials), 2:2 (for PAL materials),
Off or Auto.

With a color-bar test pattern from a test disc or other source on the TV screen, you
can make the following adjustments:
• The color intensity setting on your TV.
• Color adjustments using the color bars, which may be (left to right) black, white,
yellow, cyan (turquoise), green, magenta, red, blue, black.
• The color transition, seen as sharp separation of the bars.
• The performance of the color circuits in your TV (with video signals); bar edges
should show no vertical crawling dots.
Use the gray scale and the black/white fields in the test pattern to adjust the
brightness and contrast.
Brightness Adjustment
1. Turn down the color control on your TV until the color bars appear in black and
white.
2. Adjust the Contrast to the lowest level where you still can see all gray-scale bars
separately and clearly.
3. Adjust the Brightness so that the bars in the gray scale are all visible. The bar
farthest to the left has to be as black as possible rather than gray, but the next
gradation must clearly be distinct from it. The bars in the gray scale should
gradually and evenly change from black to white.
