Digital Projection Showlite 3000sx, 4000gv User Manual

							Picture
The Picture menu provides access to the image controls.
Brightness - adjust the level of brightness or the black raster intensity.
Contrast - adjusts the intensity of the image according to the incoming signal.
Saturation - adjusts the saturation at the white peak.
Color - increases or decreases the color saturation level (not available for RGB).
Hue - Varies the color level from +/- green to +/- blue. The red level is used as 
reference. This adjustment is only valid for Video and Component inputs.
Sharpness - controls the detail of the image for video (not available for RGB or
Component signals).
V-Aperture- Adjusts edge enhancement in the vertical direction (not available for
RGB).
Gamma Correction- This feature allows you to adjust the image for different
environments. Normal should be used when in a lighted room and either Natural 1
or Natural 2 for darkened rooms. Natural 1 provides true color reproduction of 
natural tones (e.g. flesh tones) and Natural 2 provides true reproduction of middle
tones (dark portions of a picture).

							White Balance
This feature adjusts the white balance for each input signal and provides options to
modify the Color Temperature, Brightness, Contrast and Signal Level.
Color Temperature- This feature adjusts the colour temperature of the image via a
slide bar using the left and right cursors. Moving the slide bar to the left decreases
the temperature, producing a reddish image while moving the slide bar to the right,
increases it for a bluish image.
Brightness- Allows the brightness of each colour (Red, Green and Blue) to be
changed to adjust the black level of the screen.
Contrast- Allows the contrast of each colour (Red, Green and Blue) to be changed
to adjust the white level of the screen.
Signal Level- Allows the adjustment of RGB, Component or HDTV Gain to match
multiple projector color uniformity. Adjustment can be made to the Red, Green,
Blue, Y, Cb and Cr signal levels via a slide bar.

							Image
The Image menu provides access to the Pixel Adjust, Position, Aspect Ratio,
Resolution, Overscan, Video Filter and Blanking features of the projector.
PIXEL ADJUST
Active only when Auto Adjust is turned off, Pixel Adjust allows the Clock and
Phase to be adjusted to fine tune the displayed image.
Clock - Used to fine tune a computer image or to remove any vertical banding that
might be present.
Phase - Adjusts the clock phase to reduce video noise, dot interference or cross talk.
Phase should be used only after ÔClockÕ adjustments have been made.
POSITION
When Auto Adjust is turned off, Position allows you to manually set the horizontal
and vertical image location on the screen.

							ASPECT RATIO
This feature allows you to define the correct proportions for displayed image. You
can define the aspect ratio for both the input signal and display area. Selection of
the appropriate ratio is made via the cursor buttons.
When Resolution is set to Native, this feature is not available and the stored 
settings and adjustments are invalid.
RESOLUTION
When Auto Adjust is turned off, Resolution allows you to activate or deactivate the
Imaging Resizing feature. There are two settings - Auto and Native.
Auto - Turns on the Advanced AccuBlend feature. The projector automatically
reduces or enlarges the current image to fit the full screen.
Native - Turns off the Advanced AccuBlend feature. The projector displays the 
current image in its true resolution.
If you are displaying an image with higher resolution than the projectorÕs native
resolution, even in Native mode, the image is displayed full screen using the
Image Resizing Feature.

							OVERSCAN
Sets the overscan percentage for RGB signals.
When Resolution is set to Native, this feature is not available, and the stored 
settings and adjustments are invalid.
VIDEO FILTER
This feature reduces video noise and is only available when Auto Adjust is off.
When activated a low-pass filter is applied, when deactivated the filter is removed.
Selection is made using the left and right cursor buttons.
BLANKING
This feature allows you to blank off any unwanted part of the screen image. When

							Video Adj
NOISE REDUCTION
This feature is used to reduce video noise. Select Off, Low, Medium or High to give
the optimum image.
The lower the Noise Reduction level, the better the image quality. Increasing
Noise Reduction lowers video bandwidth.
COLOR MATRIX
The Color Matrix feature is only available for component video signals. To use this
feature first select an appropriate color matrix for your input signal, either HDTV or
SDTV. Next, select an appropriate matrix type, the options available are B-Y/R-Y,
U/V, Cb/Cr, Pb/Pr or IVX.
Y/C DELAY
Adjusts the Y/C delay level. Adjustments can be made from -8 to +8 using the left
and right cursor keys.This feature is not available for RGB and DVI digital inputs.

							TELECINE
Telecine uses 3:2 pull down to eliminate jitter and artefacts in video. This option
should be set to Auto for film sources such as a DVD player and set to off for non
film sources.
MOTION SELECT
Sets the interpolation method as either Still or Adaptive. Still should be selected for
non moving images (e.g. images from a document camera) and Adaptive should be
selected for all motion video.
MOTION LEVEL
Adjusts the level of motion detection when Adaptive is selection for Motion Select.
YTR ADJUSTMENT
Adjusts the luminance transient time. Adjustments can be made to either the Gain or
Tap using the left and right cursor keys.This feature is not available for RGB and
DVI digital inputs.
CTR ADJUSTMENT
Adjusts the chroma transient time. Adjustments can be made to either the Gain or
Tap using the left and right cursor keys.This feature is not available for RGB and

							Option Adj
The Option Ref menu provides access to the Clamp Timing, Sync Protection and
VD Delay features.
CLAMP TIMING
According to the signal, this function sets the detected position (i.e. clamp position)
of the black level reproduction of the analog input signal. Normally this is not used
(1080P is set as the default).
Auto- this is the normal setting.
Tri-Sync- should be set for HDTV signals.
Front Porch- is used when the picture quality does not improve even though Auto
or Tri-Sync has been set.
Adjust- permits the video clamp position for each signal to be set. Adjust should
be used when a clamp timing error occurs at the time of special analog signal 
reception such as 1080P.
Adjust is not valid for doubler signals such as NTSC and PAL.
To delete the ÔClamp TimingÕ setting screen, select the SELECT down cursor 
button and press the ENTER button, or press the remote control CANCEL button.

							SYNC PROTECTION
When a VCR, DVD or some other equipment that supports Copyguard (a copy 
prevention system) is played back, the screen may be displayed in a curved manner.
If this is the case, Sync Protection can be used to adjusted to compensate.
VD DELAY
VD Delay is used to correct vertical jitter of non-standard interlaced signals.
If the image from a Scan Converter is not displayed correctly, the VD Delay
should be adjusted.
Signal Type
This feature is available for the RGB 1 and RGB 2 inputs only and defines the
expected signal type as either an RGB or Component signal.
Volume adjusts the sound level of the projector. You can display the volume bar
without operating the menu system (see ÔDirect Key CombinationsÕ, page CÑ6 for
details).
Keystone
Keystone is the distortion of a projected image that usually creates a wider top than
bottom. Aiming a projector upward on a wall rather than straight at a wall creates
this distortion. This feature corrects keystone distortion by increasing or decreasing
the top or bottom of the image to generate a geometrically correct image.

							Depending on the type of graphics being used, keystone correction may not be 
possible or the picture may get blurred or when excessive correction is used.
To correct the keystone distortion, use the left and right cursors 
The maximum keystone angle that can be corrected is 30 degree upwards and 30
degree downward with the projector placed horizontally on the ground plane.
When Resolution is set to Native, this feature is not available, and the stored 
settings and adjustments are invalid.
Lamp Mode
Lamp Mode defines the brightness mode of the lamp - High Bright or Eco mode.
The default mode is High Bright. Eco mode can extend the life of the lamp up to
2000 hours.
If you select Eco mode, the projector will startup in High Bright mode and
change to Eco mode after 3 minutes.
Ref. White Bal.
This feature adjusts the white balance that is used as a reference. This adjustment
affects all sources and is available for Test Pattern only.
