Video Adjustments Menu - Harman Kardon HS100 Service Manual

HS100
Integrated Home Theater System
• Progressive: Select this option if you have a video
display that is compatible with input sources of 480p
or greater. Displays labeled as "HDTV Ready, " includ-
ing virtually all large-screen LCD and plasma dis-
plays, are compatible with progressive scan.
• Interlaced: Select this option when you are using
an older video display that has Y/Pr/Pb component
inputs, but which is not capable of displaying high
scan rate, or "HD, " signals.
Video Mode: This setting affects only the Com-
ponent Video Outputs ⁄, and it controls how the
video signals are optimized for progressive scan dis-
play. In most cases, the "automatic" mode is your best
choice, as it senses whether the disc being played was
originally recorded on video or shot on film. However,
in some cases you may wish to compensate for errors
in the disc authoring that occur when the frame rate is
not properly maintained when films are converted to
video. Three choices are available:
• Auto: This is the recommended setting, as it lets the
HS 100 analyze the signals from the DVD and adjust
the output accordingly.
• Movie: Choose this option for optimal playback of
material that was shot on film, even though you are
viewing it on video via a DVD.
• Video: Choose this option for optimal playback of
material that was shot directly to video, such as con-
certs and sports programming.

Video Adjustments Menu

This menu allows you to adjust five key parameters
of the video signal to compensate for differences
between HS 100 and other video sources. You may
use either the HS 100's built-in color bar test signal
or a test disc as the standard for the adjustments. To
ensure that your system is properly optimized, we
strongly recommend that you adjust your video display
using the display's own controls before making any
changes to the HS 100's output. Once the display is
properly calibrated with all settings on the HS 100 set
to their midpoint, use the controls on this menu to fine-
tune the HS 100's output.
Due to the nature of these settings, the navigation is
somewhat different from the HS 100's other menus
and controls. The menu itself is called up in the same
way as the other menus. Press the OSD Button y
to activate the main menu screen, and then press the
Navigation Buttons k so that SETUP

is highlighted. Press the Enter Button z, and then
Navigation Buttons k until
M N K L
use the / / /
the VIDEO ADJUSTMENTS menu box
(which contains an icon with slider controls and the
word VIDEO, and is located at the bottom of the
column in the Submenus Area ∫) is highlighted
within a white outline. Then press Enter z again.
When you press Enter z the video adjustments will
appear inside a black bar at the top of the screen, with
either the video from a disc being played or the splash
screen shown on the rest of the screen.
To change any of the video adjustments shown at
the top of the screen, first press the M
Navigation Buttons k so that the "+" to the right
of a parameter name is highlighted to increase the set-
ting or "–" to the right of a parameter name is high-
lighted to decrease the setting. Then press the Enter
Button z to change the value as shown by the
number of blue lines to the left or right of the center
line. When only the dark center line is shown with no
blue lines, the setting is at the midpoint default value.
When adjusting the Black Level setting, note that the
adjustment available is to either have the setting at the
midpoint, which provides a full "0 to 100" black level
setting, or "full," which complies with standards for
video with what is called "setup, " or a "7.5 to 100"
black level setting.
Changes to any of the settings may be made with
a test disc playing, or you may use the internal test sig-
nal by pressing the M / N / K / L Navigation Buttons
k until the word OFF is highlighted next to the
TEST SCREEN line. To activate the test signal,
press the Enter Button z and note that a special
combination test signal, including both color bars and
gray scale along with 100% black and white fields, will
be displayed. To recall the video controls, press the
OSD Button y and then navigate among the set-
tings and make any necessary changes following the
steps in the previous paragraph.
Test Screen
With the test screen showing on your video display, the
following adjustments may be made:
• The proper color intensity setting on your TV.
• Proper color adjustments using the color bars, which
should be (left to right) black, white, yellow, cyan
(turquoise), green, magenta, red, blue, black.

SYSTEM SETUP
• The proper 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
/ N / K / L
no vertical crawling dots.
With the gray scale and the black/white fields below
the color bars, the brightness and contrast of your
screen can be adjusted.
TV Picture Adjustment With Test Screen
Brightness Adjustment:
1. Turn down the color control on your TV until the
color bars are visible in black and white.
2. Adjust the contrast to the lowest level where you still
can see all bars within the gray scale in the test pic-
ture separately and clearly.
3. Adjust the brightness so that the bars in the gray
scale are all visible. The bar furthest to the left has to
be as black as possible rather than gray but the next
gradation must clearly be distinct from it. All the bars
in the gray scale should be gradually and evenly
changing from black to white, left to right.
Contrast Adjustment:
1. Adjust the contrast on your TV until you see a bright
white bar in the lower right corner of the screen and
a deep-dark-black bar to the left. The optimal con-
trast setting will depend on your preference and the
surrounding light in the TV room.
2. If the brightness of the white bar no longer increases
when the contrast is turned up or the borders of the
white "harman/kardon" letters on top bloom (over-
light) into the black areas (drastically decreasing
the sharpness of the type), the contrast has been
turned up too much. Reduce the contrast until these
effects disappear and the video still looks realistic.
3. If you are watching TV with customary surrounding
daylight, adjust the contrast so that a normal video
picture has about the same look as the surroundings
in your room. That way the eye is relaxed when
watching the TV picture. This contrast setting may be
reduced when the surrounding light is dimmed,
thereby usually improving the sharpness of a video
significantly.
4. The gray scale in the middle line needs to have
the same clear difference between each bar as
harman/kardon
