VIDEO ADjUSTMENTS
VIDEO ADJUSTMENTS
The AVR 260 includes sophisticated DCDi by Faroudja video processing
that delivers enhanced video quality, even for older analog video source
components, as well as upgraded on-screen displays. When upscaling video
materials from a lower resolution to a higher one (the AVR 260 upscales to
a maximum of 1080p), the processor is adding pixels to the original image.
Sometimes when converting interlaced video (displays all odd rows then
all even rows of the frame) to progressive-scan video (displays all rows at
once) and increasing the resolution, the interpolation of new pixels can
cause jagginess, or a staircase effect, at edge transitions, such as the stripes
in an American flag. Faroudja engineers developed the DCDi (Directional
Correlational Deinterlacing) algorithm to ensure that the additional pixels
follow the edge, virtually eliminating the jagginess and enhancing upscaled
images.
Thanks to the “Torino” video processing chip, on-screen graphics may be
generated in high definition, and blended with the incoming video. This not
only delivers crisp, clear information messages, it allows you to continue to
watch a program while making system adjustments.
Video Modes
After you have adjusted the picture settings on your video display, additional
adjustments may be made to the AVR, if necessary, to further improve the
picture. Access these settings from the Video Modes menu. Press the Video
Modes Button on the front panel or remote, and the screen shown in Figure
17 will appear. The menu may also be accessed from the Setup Source menu
by pressing the Info Settings Button and selecting the Video Modes line.

Video Mode
: The default setting of Processor Off passes the video signal
through to the display without any processing. Select one of these processing
options to optimize the picture for the current program by applying
adjustments to the brightness, contrast, color and sharpness:
Sports
• : For sporting events.
Nature
• : For programs shot outdoors, in a natural setting.
Movie
• : For movies and many television broadcasts.
Custom
• : Allows manual adjustment of the picture settings. The
Brightness, Contrast, Color and Sharpness settings will appear on screen
as sliders with values ranging from 0 to 100. The default setting for each
adjustment is 50. Use the
M N
Buttons to change each setting’s value.
Picture Adjust
: Use this setting to change the aspect ratio of the displayed
image.
When displaying widescreen (16:9) images on a full screen (4:3) device,
letterbox format will be used, in which black bars may appear above and
below the image (pillarboxing).
When displaying full screen images on a widescreen device, black or gray bars
may appear to the left and right of the image.
Some displays, especially 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. Use this setting to adjust the picture so that it fills
the display’s screen. The options are:
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 pillarbox format may be
used. If the image is in the 16:9 aspect ratio, on full screen (4:3) displays
letterbox format may be used.
Zoom 2x
• : Stretches the image evenly to completely fill the screen. The
outer portions of the image may be cropped.
Feel free to experiment with this setting for each source until you find a
pleasing display format for each program.
Advanced Video Settings
: Press the
N
or OK Button to display the
Advanced Video Modes submenu (see Figure 18).

Noise Reduction
: To reduce signal noise, choose between LOW, MEDIUM,
HIGH or OFF with the OK button
V
. It is advisable to use as low a step as
possible, as high levels of Noise Reduction may impair other aspects of the
image.
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 “pixellate” into blocks, change the MPEG
Noise Reduction setting from its default of Off to the Low, Medium or High
setting to improve the picture.
