On your external test pattern source, select a PLUGE pattern. (PLUGE is\
 an acronym for “Picture Line-Up 
Generation Equipment.”) Figure 4-9 shows a typical PLUGE pattern.
PLUGE patterns vary but generally consist of some combination of black, \
white and gray areas against a black 
background. The example above includes two vertical bars and four shaded\
 boxes.

Figure 4-9: Typical PLUGE Pattern for Adjusting Brightness
Brightness: Select Brightness from the Image menu. Use the  or  buttons to adjust the level so that: 
The darkest black bars disappear into the background. 
NoteFor best results, Vivitek recommends that you set Dynamic Iris to Off before adjusting Brightness, 
Contrast and other image quality settings in IMAGE menu (refer to Dynamic Iris on page 50). After 
you have completed the initial calibration, set Dynamic Iris to On if desired. 
The dark gray areas are barely visible.
The lighter gray areas are clearly visible.
The white areas are a comfortable level of true white.
The image contains only black, gray and white (no color).

Contrast: On your external test pattern source, select a stepped, gray-bar patter\
n like the one shown in Figure 4-10.
Figure 4-10: Typical Gray Bar Pattern for Adjusting Contrast
Select Contrast from the IMAGE menu. Use the  or  buttons to adjust the contrast up until the top two bars be-
come almost the same brightness, then down just until the brightness cha\
nge between these bars is consistent with 
the other bars.
NoteBrightness and Contrast controls are interactive. A change to one may require a subtle change to 
the other in order to achieve the optimum setting. 
Color Saturation: To adjust the overall color intensity, select Color Saturation from th\
e IMAGE menu. Decrease this 
setting if colors are overly saturated; increase it if colors appear mut\
ed or washed out.
Color Tint: Tint or “hue” is the ratio of red to green in the color portion of\
 the image. To adjust the tint, select Color 
Tint from the IMAGE menu. Decrease this setting to shift the hue toward \
red; increase it to shift the hue toward green.
NoteLike the Brightness and Contrast controls, the color and tint controls are interactive. A change to 
one may require a subtle change to the other in order to achieve the optimum setting.
Sharpness: Sharpness is the amount of high-frequency detail in the image.

To adjust this, select Sharpness from the IMAGE menu and press ENTER. On\
 your external test pattern source, se-
lect a pattern like the one shown in Figure 4-12.
Figure 4-12: Typical Test Pattern for Adjusting Sharpness
Sharpness (Simple Mode): Adjust as needed, looking for white edges aro\
und the transitions from black to gray 
and differently-sized lines in the “sweep” patterns at the top and\
 bottom. Lower the sharpness setting to elimi-
nate them.
Sharpness Mode: Sharpness Mode allows or prevents access to the detailed\
 sharpness controls in this menu.  
In most cases, Simple mode provides a sufficient level of control to pro\
duce the best picture from the most popu-
lar sources. In Simple mode, only the Sharpness (top-most) slider is a\
djustable; the others are grayed out.
Horizontal Sharpness / Vertical Sharpness / Diagonal Sharpness: Use thes\
e controls to enhance image detail 
along horizontal, vertical and diagonal edges respectively. 
Sharpness Overshoot: Use the Sharpness Overshoot control to minimize or \
eliminate rings or shadows on domi-
nant edges that cannot be removed using the “simple” Sharpness con\
trol. 
Horizontal Texture / Vertical Texture / Diagonal Texture / Texture Overs\
hoot: Use these controls to remove arti-
facts from textured areas that cannot be removed using the “simple”\
 Sharpness control. 
Noise Threshold: The Noise Threshold setting adjusts the frequency below\
 which the Sharpness controls have 
an effect. Frequencies above the threshold are considered “noise.”\
  
 
Generally, the higher the setting, the more noticeable the effect of any\
 adjustments will be.

Noise Reduction: To apply noise reduction to the source signal, select Noise Reduction fr\
om the IMAGE menu and 
press ENTER. 
Figure 4-13: Noise Reduction Sub-Menu
Noise Reduction is useful for clearing up noisy images from interlaced S\
D sources.
Noise Reduction (Simple Mode): Use the  or  buttons to adjust as desired, keeping in mind that reducing 
noise (which reduces high frequencies) may also soften the image. 
Noise Reduction Mode: Noise Reduction Mode allows or prevents access to \
the detailed noise reduction con-
trols in this menu.  
In most cases, Simple mode provides a sufficient level of control to pro\
duce the best picture from the most popu-
lar sources. In Simple mode, only the Noise Reduction (top-most) slide\
r is adjustable; the others are grayed out. 
Choose Advanced mode if you need more precise control over noise reducti\
on. In Advanced mode, only the top 
slider is grayed out.
General Noise Reduction: General Noise Reduction is temporal and spatial\
 noise reduction for all types of 
inputs. The scene is analyzed for differences from frame to frame and re\
duces those differences that are not de-
termined to be motion.
Block Artifact Reduction: Use this control to reduce or eliminate so-cal\
led “block artifacts” in MPEG-compressed 
video signals (digital broadcasts or DVDs). Set it as needed to minimi\
ze distortion within horizontal and vertical 
block boundaries. 
Mosquito Noise Reduction: Use this control to reduce or eliminate so-cal\
led “mosquito noise” in MPEG-com-
pressed video signals. Set it as needed to minimize distortion around th\
e edges of moving objects, moving 
artifacts around edges and/or blotchy noise patterns superimposed over t\
he objects.
Overscan: Some television programs are produced based on the assumption that older\
 television sets may not 
display the outer edges of the broadcast picture area. Overscan effectiv\
ely hides these inactive, outer edges of the 
image. Choose one of the following:
Off: This setting leaves the image as-is.
Crop: This setting adds a mask at the left and right edges of the source\
 active image equal to 3% of the dis-
played horizontal resolution, and at the top and bottom edges equal to 3\
% of the displayed vertical resolution.
Zoom: This setting adds a factor to the scaling of the source active ima\
ge so that the vertical and horizontal 
resolutions are 106% of the size determined by the aspect ratio function\
. Anything outside of the original image 
area is removed.

ADVANCED
Use the controls in the ADVANCED menu, shown in Figure 4-16, to perform \
advanced image adjustments.
Figure 4-16: H9080FD ADVANCED Menu
Color Space: Select Color Space from the ADVANCED menu to choose the color space of t\
he source signal for 
HDMI, RGB, and component connections. 
The default setting, Auto, functions as follows:
HDMI: If the Auxiliary Video Information (AVI) infoframe contains colo\
r space and/or range data, the H9080FD 
uses that information. Otherwise, for RGB sources, the H9080FD uses the \
RGB-Video color space.  For compo-
nent SDTV and EDTV resolutions, REC601 is used. For other component vide\
o resolutions, REC709 is used.
RGB: If Hsync or Vsync signals are present, the H9080FD uses the RGB-PC \
color space. Otherwise, REC601 is 
used for SDTV and EDTV sources, and REC709 for all other sources.
Component: For SDTV and EDTV resolutions, the H9080FD uses the REC601 co\
lor space. For all other resolu-
tions REC709 is used.
In most cases, the Auto setting determines the correct color space to us\
e. If it does not, you can force the H9080FD 
to use a specific color space. Choose one of the following:
REC709 sets the color space matrix to that defined in ITU-R BT.709.
REC601 sets the color space matrix to that defined in ITU-R BT.601.
RGB-PC uses RGB color space and sets black at 0,0,0 RGB and white at 255\
,255,255 RGB, assuming an 8-bit 
image.
RGB-Video uses RGB color space and sets black at 16,16,16 RGB and white \
at 235,235,235, assuming an 8-bit 
image, to correspond to the luminance values defined in digital componen\
t standards.

Video Standard: Select Video Standard from the ADVANCED menu to specify the color system\
 for composite 
video or S-Video input signals.  
Different countries use different formats for video signals. Select the \
appropriate Video Standard for your region: 
Auto: The color systems are automatically identified and the format is s\
et accordingly.
NTSC: This is the standard format used mainly in the United States and J\
apan.
PAL: This is the standard used in Europe, Australia and many other parts\
 of the world, typically with a 50Hz 
frame rate. 
SECAM: This is a standard format used mainly in France and Russia. 
Gamma: Select Gamma from the ADVANCED menu to choose a DLP de-gamma curve. Used\
 correctly, the 
Gamma control can improve contrast while maintaining good details for bl\
acks and whites.  
If excess ambient light washes out the image and it becomes difficult or\
 impossible to see details in dark areas, low-
er the gamma setting to compensate. This improves contrast while maintai\
ning good details for blacks. Conversely, 
if the image is washed out and unnatural, with excessive detail in black\
 areas, increase the setting.
CRT sets the gamma to 2.5.
Film sets the gamma to 2.2.
Cinema is similar to Film gamma but differs in dark areas of the image t\
o correspond to the function that video 
cameras use to create images. 
Bright sets the gamma to 2.0.
Graphics should only be used for computer presentations that require inc\
reased brightness at the cost of gray-
scale accuracy.
Color Temperature: Select to set the projector’s color temperature. Range: Warm, Standard (default), Cool, Cooler.
DLP Frame Rate: Select DLP Frame Rate from the ADVANCED menu to choose the output frame \
rate. You can 
have the H9080FD automatically determine the optimum frame rate, or you \
can force it to use a specific frame rate. 
The default setting, Auto, frame locks to the main source if it has a ve\
rtical refresh rate of between 48 and 62Hz. 
Vertical refresh rates of from 24 to 31Hz are doubled. Frame rates betwe\
en 31 and 48Hz and greater than 62Hz are 
converted to 60Hz.
Select 48Hz to force the output frame rate to 48Hz. Use this setting to \
eliminate 2:3 pull-down judder with 60Hz 
film-based sources.
50Hz and 60Hz force the output frame rate to 50Hz and 60Hz respectively.\
Color Gamut: Press the  or  buttons to select the Golor Gamut values. The default setting is Auto.
BrilliantColor: Press the  or  buttons to enable or disable BrilliantColor.
Dynamic Iris: Press the  or  buttons to enable or disable Dynamic Iris.
Adaptive Contrast: Adaptive Contrast enhancement expands the light and dark portions of an \
output image ac-
cording to the mean luminance of the input image.

RGB Adjust: To remove any trace of color from the white areas of the projected image\
, choose RGB Adjust from 
the ADVANCED menu and press ENTER. This displays the RGB Adjust sub-menu\
, shown in Figure 4-17.
Figure 4-17: RGB Adjust Sub-Menu
Offset: Use the Offset controls in the RGB Adjust sub-menu to correct co\
lor imbalances in the dark areas of 
the image. A good way to do this is to use a test pattern consisting mos\
tly of dark gray areas, such as a 30 IRE 
“window” pattern. If the gray areas contain traces of red, green o\
r blue, decrease the Offset for that color.
Gain: Use the Gain controls to correct color imbalances in the bright ar\
eas of the image. A good way to do this 
is to use a test pattern consisting mostly of solid white areas, such as\
 an 80 IRE “window” pattern. If the white 
areas contain traces of red, green or blue, decrease the Gain for that c\
olor. 
 
The Gain controls increase or decrease the full-scale input range; the O\
ffset controls shift the entire range, re-
sulting in a change in brightness.
NoteGenerally, higher Gain settings reduce the image contrast; higher Offset settings reduce the image 
brightness.
