5)
Component Input
Ð refers to the video signal
in its component form (Y, R-Y, B-Y or Y, Cr, Cb for
DVD) carried in a 3-wire cable.
6)
Brightness
Ð The Brightness control adjusts the
black levels in the image. The level should be adjust-
ed so that the color black is achieved (not gray) yet
faint details should still be observable in the shad-
ows. It is best to use a test pattern known as a
PLUGE to set the levels.
7)
Contrast
Ð This control adjusts the level of white in
the image. Using a well-lit image, adjust the contrast
for the brightest image but not so bright that white
areas start to turn green or cause blooming.
Blooming is seen as bright areas of the picture
smearing off to the left. It is best to use a test pattern
known as PLUGE to set the levels.
8)
Color
Ð This adjusts the amount of color in the
image. Adjust to individual taste. The VP301 has an
AGC (Automatic Gain Control) that adjusts the color
level automatically to maintain optimum color set-
tings using the customerÕs adjusted setting as a ref-
erence. It is best to use a test pattern known as
SMPTE color bars with a blue filter to properly set
the levels.
9)
Tint
Ð This adjusts the color phase seen as the
range from green to magenta. The VP301 has an
APC (Automatic Phase Control) that maintains prop-
er phase. This setting is best left in the preset posi-
tion. It is best to use a test pattern known as SMPTE
color bars with a blue filter to properly set the levels.
10)
Noise Reduction
Ð This adjusts the visibility of
small edge details such as film grain and dust.
Lowering the level increases the visibility of this
type of noise. Increasing the level helps to filter
them out. For most sources, this should be left in
the preset setting.
11)
Detail
Ð This control adjusts the amount of large
edge details such as black to white transitions. The
level should be set where there is the maximum
amount of edge detail without excessive ÒringingÓ
and harshness. For most sources, this should be
left in the preset setting.
12)
Digital Filter
Ð This control eliminates edge
breakup caused by poor quality compression on
some satellite channels.
It should never be used
with higher quality sources such as DVDs,
laserdiscs, and high quality satellite channels.
13)
Freeze
Ð This control captures a video frame for a
high-resolution still image. Pressing the button again
unfreezes the image. (Note: the freeze function must
capture both video fields for a clean image. Using
the freeze on a fast moving image may create a
lined image, a result of only a partial video frame
capture. Refreezing the image should yield smooth
results.)
14)
Store
Ð Press this button to activate the store func-
tion. The next preset pressed will store the current
settings.
15)
Factory
Ð The Factory Presets are set to broadcast
industry standards. And can be used as a reference
or to reset levels if they get misaligned.
16)
Preset
Ð This control stores all picture adjustments
in a nonvolatile memory. There is a separate bank of
four presets for each input, that are automatically
recalled when the input is selected.
17)
IR Window
Ð Receives the information from the
remote control. Do not block this sensor.
18)
Value Adjust
Ð This rocker switch adjusts the value
of each function. Pressing the top portion increases
the level, pressing the bottom portion reduces the
level.
DETAIL CONTROLS
The VP301 offers two controls for enhancement, Noise
Reduction and Detail. The two controls work together to
provide optimum picture detail without introducing ÒringingÓ
artifacts for both horizontal and vertical edges. This is very
helpful with low quality sources such as VHS tapes. Also,
even high quality sources such as DVDs and Laserdiscs
can have excessive detail enhancement recorded in the
movie this can be seen as white halos along dark edges.
The detail controls can be reduced, to limit the visibility of
the halos.
However, for the most part, the settings should be left in
the preset setting. If the detail level must be turned way up
to see details, there is a good chance there are other fac-
tors involved, such as the projector becoming out of focus
or poor cable quality. Contact the dealer for assistance.

The adjustment levels can also be seen on the
projection screen for easy adjustment.
