TEST SCREEN

ENGLISH

Test Screen

When you activate the Test Screen via the OSD
you can activate a still image to test all settings
and the video performance of your TV. With the
vertical color bars you can test the following:

■

proper color intensity setting on your TV,

■

the proper color of each bar, showing if the
proper video standard is turned on: the colors
should be (left to right): black, white, yellow,
cyan (turquoise), green, magenta (purple), red,
blue, black.

■

proper color transition, seen as sharp
separation of the bars, S-Video will be better
than Video, RGB best of all.

■

the performance of the color filter in your TV
(with ”Video” signals), bar edges should show
no vertical crawling dots. Here S-Video and
RGB formats usually give no problems.

With the grey scale and the black/white fields
below the color bars the brightness and contrast
of your screen can be adjusted optimally, see
chapter ”TV Picture Adjustment” below.

TV Picture Adjustment with
Test Screen

These adjustments may be done now, but you
can also make them after setup has been
finalized.

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 grey scale
in the test picture separately and clearly.

3. Adjust the Brightness so that the bars in the

grey scale are all visible. The bar furtherst to
the left has to be as black as possible rather
than grey but the next aside must clearly be
differable. All the bars in the grey scale have to
be gradually and evenly changing from black
to whiter, going from left to right.

Contrast adjustment:

1. Adjust the contrast on your TV until you see a

bright white bar in the right low corner of the
screen and a deep dark black bar at the left.
The optimal contrast setting will depend from
your preference and the surrounding light in
the TV room.

2. If the brightness of the white bar will no more

increase while turning up the contrast or when

the borders of the white ”harman/kardon” text
letters on top will bloom (overlight) into the
black areas, what drasticly will decrease the
sharpness of the script, then the Contrast has
been turned up too much. Reduce the contrast
until these effects will disappear and the video
still looks realistic.

3. If you are watching TV with a usual surround-

ing daylight, adjust the Contrast so that a nor-
mal video picture has about the same looking
as the surroundings in your room. By that way
the eye is relazed when watching the TV
picture. This contrast setting may be reduced
when the surrounding light is dimmed, usually
improving the sharpness of a video a lot
thereby.

4. The grey scale in the middle line needs to have

the same clear difference between each bar as
before the contrast adjustment. If not, go back
to the brightness adjustment and repeat step 3
and then the contrast adjustments, making
only minor adjustments each time for
optimisation.

Color adjustment.

1. When the Brightness and the Contrast are set

optimally, turn up the color control to the level
of your perference. Adjust to the level where
the colors look strong but still natural, not
overdone. If the color level is too high,
depending from the TV used some of the bars
will seem wider or the color intensity will not
increase while the control is turned up. Then
the color control must be reduced again. At the
end you should test the color intensity also
with a video, e.g. pictures of natural faces,
flowers, fruit and vegetables and other well
known natural articles of our life most usefull
for an optimal setting of the color intensity.

2. If your TV has a Tint option (with most

European TVs this is available or effective only
with NTSC signals, not with PAL), use the large
white bar below the Greyscale to tweak the
warmth of the picture. Every viewer has a
difference in preference as how the glow of
the picture should be. Some prefer a little
colder picture, some a warmer glow. The Tint
function on your TV and the white bar can be
used to control this. Adjust the Tint to the level
where you feel the white color has the tone
you prefer.

Sharpness Adjustment

Contrary to intuition, the picture will appear
sharper and clearer with the sharpness, or Edges,
setting backed off from the maximum setting.
Reduce the sharpness setting on your television,
and the Edges setting on the HS 500 video
adjustments menu if necessary, to minimize the
appearance of any white lines between the bars
in the gray scale portion of the test screen.

Convergence and Edge Focus

The crosshatch pattern that surrounds the test
screen may be used to evaluate edge focus and
convergence in front- or rear-projection video
displays. However, the controls used to adjust
these parameters are often not user-accessible.
In any event, these adjustments are extremely
complex, and require proper training and
experience to avoid worsening the situation.
Therefore, it is recommended that if you are
unable to improve the picture using the available
controls, contact the video display manufacturer’s
authorized service representative for assistance.

When all desired setup and configuration entries
have been made, use the

Navigation

Buttons

until “Done” is highlighted at the

bottom of the Video Adjustments submenu. Press
the

Enter Button

to select it to return to

the on-screen menu system. Then, press the

Setup Button

to remove the menu displays

from the screen. The unit will return to normal
operation and you are ready to enjoy the finest in
DVD or CD playback!

Picture Calibration Using the supplied
Test Disc

When doing the calibration first insert the disc in
the Disk tray. The disc will start reading, and a
main menu will appear on the screen. Select the
test pattern required using the

Buttons

. Once the pattern appears on the

screen, press the

Pause Button

to make

sure the test pattern will stay long enough on the
screen to make the adjustments.

With the requested test pattern on the screen
press the

Mode Button

repeatedly until

the TV Button turns red. This will change the
remote control to the TV mode, without changing
the system's source to TV. Next, press the

Setup

Button
