3.5 Size and Position Menu
Increase or decrease the size of your image, change 
its proportion (aspect ratio), move the image to a 
specific area of the screen, and refine other related 
parameters. Use Size and Position controls to 
match the image precisely to the screen used at the 
site.
See 3.2.4 How to Use Slide Bars and Other 
Controls if you need help using any of the options 
and controls. Changes made in the Size and 
Position menu are applied immediately and are 
saved when you exit the menu (press E
XIT or 
M
ENU).
3.5.1 Resize Presets
NOTE: The same resize presets are available to all HD and SXGA+ screen models. However, the graphics 
used to describe each preset in this section are of the SXGA+ models only. 
Resize Presets will display an image in its native 
resolution (no resizing) or will resize the image 
by maximizing either the height, width or both 
height and width, or will resize to the maximum 
size possible while keeping the original aspect 
ratio. 
Size, Position and Blanking parameters will 
automatically adjust accordingly or, if Blanking 
is set first, which defines an active input area; 
Resize Preset scaling will occur in this region of 
interest only. Resizing options are explained 
below.
Default Resizing: By default when displaying a new source, your image will utilize as much of the display 
area as possible for the type of incoming source data, but with minimal or no changes to aspect ratio. 
The “Custom” re-size descriptor automatically appears in the Size and Position menu when any of the values 
for Size, Vertical Stretch, H-Position, V-Position or Blanking do not correspond to those for a preset. This 
option is not offered in the Resize Presets pull-down list.
• Select default for most sources (factory default). The image will be centered and displayed as large as 
possible depending on the type of source.

Section 3: Operation
•No resizing displays the image in its native resolution, which may or may not match the projector’s 
resolution. For example, for a source with a native resolution of 800 x 600, “No Resizing” in an SXGA+ 
projector will use the central 800 x 600 pixels and have a black border. The black border areas are unused 
areas, see below.
•Full size uses all pixels for displaying the image, regardless of source or original aspect ratio. Incoming 
source material having a different aspect ratio than the projector will be stretched for display.
•Full width fills the display from left-to-right without changing the original aspect ratio of the image. 
Depending on the source, data at the top and bottom may be discarded (cropped), or the display may have 
black borders at the top and bottom (called “letter boxed”). 
•Full height fills the display from top-to-bottom. Depending on the source, this may create borders. 
•Anamorphic displays an anamorphic image in its native 16:9 aspect ratio. The image will fill the screen 
from side-to-side and be centered between black bars at top and bottom.

3.5.2 Size
Controls both the image width and height in tandem, maintaining the current aspect ratio of the displayed 
signal data. 
3.5.3 Vertical Stretch
Adjusts the height of the image while keeping the width constant. Use “Vertical Stretch” to change the aspect 
ratio of the display. 
3.5.4 Pixel Track
Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. 
Proper pixel tracking ensures that the image quality is consistent across the screen, the aspect ratio is 
maintained, and that the pixel phase can be optimized (described below). Tracking determines the frequency of 
the pixel-sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a 
particular source are sampled. 
NOTE: By default, the projector samples at the correct frequency for most sources. 
For best results, use a test pattern such as a smooth grey consisting of a clear pattern of black and white pixels, 
or a similar “half on, half off” graphic image, such as the Windows 2000 shutdown screen. Adjust the slide bar 
until the vertical stripes broaden to the point where one large stripe fills the image. If the image still exhibits 
some shimmer or noise, adjust Pixel Phase (below).
3.5.5 Pixel Phase
NOTE: Adjust “Pixel Phase” after “Pixel Track”.
Adjust pixel phase when the image (usually from an RGB source) still shows shimmer or “noise” after pixel 
tracking is optimized. Pixel phase adjusts the phase of the pixel-sampling clock relative to the incoming signal.
Adjust the slide bar until the image stabilizes and each pixel is clearly defined. You may notice that you can 
stabilize the image at more than one point.
If some shimmer from a video or HDTV source persists, use the “Filter” control to remove high-frequency 
noise from the signal.
3.5.6 H-Position
Moves the image right or left within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in relation to the total 
number of pixels available horizontally. This varies widely according to the signal; watch the image while 
adjusting.
3.5.7 V-Position
Moves the image up or down within the area of available pixels.
NOTE: The value shown represents the approximate center of the image in relation to the total number of 
pixels available vertically. This varies widely according to the signal; watch the image while adjusting.

Section 3: Operation
3.5.8 Keep Aspect On Auto Setup
Ensures that auto setup for any source will maintain the input aspect ratio when the default size is calculated. If 
disabled and the source is not a special case video source where a default stretch is defined, the source is scaled 
to fit the platform.
3.5.9 Blanking - Submenu
This submenu consists of the following options:
•Active Input Window: This read-only value indicates the current size of your displayed data or “region of 
interest” as defined by the blanking controls. By default, the projector automatically determines what portion 
of its full resolution to use, and pixels in the surrounding borders are turned off. To specify a specific active 
input window size by adjust one or more “Blank” settings. For example, if you have blanked (cropped) 100 
pixels from both the left and right edges of an incoming source of 1400 x 1050, the remaining active input 
window will be reduced to 1200 x 1050.
•Blanking (Top, Bottom, Left, And Right): Crop the image so that 
unwanted edges are removed from the display (changed to black). 
Blanking defines the size of the Active Input Window, or area of 
interest. Range of adjustment depends on the source resolution and 
other factors. 
NOTE: Blanking a PIP image resembles zoom. For example, left 
Blanking zooms the right side of the PIP image; Right Blanking 
zooms the left side. There are no black bars.

3.6 Image Settings Menu
Use the Image Settings menu to alter your main 
image without affecting its size or position. 
Changes made are applied immediately and are 
saved when you exit the menu (press E
XIT or 
M
ENU). Options not available for the projector 
model or source are disabled and appear dim 
(grey).
3.6.1 Contrast
Contrast increases or decreases the perceived difference between light and dark areas of your image (0-100). 
For best results, keep close to 50, start with a lower value and increase so that whites remain bright but are not 
distorted or tinted, and that light areas do not become white. 
NOTE: If the environment lighting changes, an adjustment of Gamma is recommended (see below).
3.6.2 Brightness
Increases or decreases the amount of black in the image (0-100). For best results, keep close to 50. Start with a 
high value and decrease so that dark areas do not become black. Conversely, high brightness changes black to 
dark grey, causing washed-out images. 
3.6.3 Yellow Notch Filter (YNF)
YNF is a channel based control with an additional global control. It works on a “last request gets served” basis. 
i.e. Enable YNF in the global control, YNF will be enabled. Thereafter; switch to a channel which does not use 
YNF, the YNF filter will be removed (or disabled). Then change the global control, the YNF filter will do 
whatever is requested; last request is honored.
3.6.4 Color Space
Determines how the color components of an analog input signal are decoded for accurate color in the display. 
Useful only for analog signals and certain digital sources. Although color space for these analog signals is 
automatically determined by the projector. You may wish to override this and manually set a color space. 
NOTE: For some signals, the color space function is entirely automatic and the pull-down list is disabled.
The current color space appears in the Image Settings menu. Press E
NTER to select a different option:
• Select RGB unless you are using component video 
• Select YPbPr (Video) with a standard definition televised signal (SDTV).
• Select YPbPr (HDTV) with a high definition televised signal (HDTV).
NOTE: When certain RGB signals are first connected, the projector may not recognize them as RGB and 
will incorrectly decode their color information as YPbPr (video). These signals can include:
•RGB signals in NTSC, PAL, SECAM frequency ranges.
•Scan-doubled sync-on-green.
•Scan-quadrupled sync-on-green.
For these signals, change the color Space to RGB, and then define a new channel for future use.

Section 3: Operation
3.6.5 Video Options - Submenu
This submenu is used with video sources only.
•Enable Decoder (AGC): AGC affects decoded video images only. Enter a check mark (default) in most 
instances. Activate the decoder’s AGC circuit to ensure properly bright images. Delete the check mark if a 
decoded video image exhibits strange color artifacts such as stripes in highly saturated colors, indicating an 
incompatibility between this source and the AGC.
•Video Standard: For most video standards available in the world, the projector automatically detects the 
incoming horizontal and vertical frequencies and sets the projector’s processing of this signal to the 
corresponding standard. The current video standard name appears in the Video Options submenu, and 
includes an “A” if it is auto-detected. Press E
NTER to view or select a different video standard from those 
available to the projector; any that are disabled have frequency characteristics that differ from those of the 
incoming signal. Selecting a specific standard forces the projector to process the signal according to this 
standard. 
NOTE: Best results are obtained with defined channels. Otherwise, switching from one video source to 
another can sometimes cause slight disturbances in the display, indicating that the Auto function is 
struggling. Recover by briefly selecting a different video standard, then going back.
•Input Video Black: This control compensates for incoming 
elevated black levels present in certain video signals, and 
ensures that blacks in the display are neither crushed (i.e., 
where dark greys appear black) nor excessively elevated 
(i.e., where blacks appear dark grey). By default, the projector automatically determines the best setting 
according to the type of incoming video signal:
•0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL standards, and Japanese NTSC.
•7.5 IRE – Used for most NTSC video signals.
For some types of video, you can override the setting. The control is disabled for other types of video (and all 
graphics sources). Generally, if black appears crushed when brightness = 50, choose “0 IRE”. If black 
appears excessively elevated, use “7.5 IRE”.
•Color: This slide bar adjusts the color saturation level. Lower settings produce less saturated colors, for 
example a setting of “0” produces a black and white image. If the color level is too high, colors will be 
overpowering and unrealistic.
•Tint: Adjusts the red/green color hue for true color reproduction of video and HDTV signals. For best 
results, adjust tint while displaying an external test pattern. It is recommended that tint remain at its default 
setting.
STANDARDWHERE USED (SUBJECT TO CHANGE)
PAL Most of Europe, China, Australia, some of S. America, some of Africa
NTSC N. America and Japan
SECAM France, Eastern Europe, most of Africa
NTSC 4.43 A tape-only standard for partially-translated hybrid signals
PAL-M Brazil
PAL-NC Argentina, Chile, other Latin American countries
PAL 60
NOTE: Generally, use “Auto” for all instances except: a poor quality input signal or a 
black-and-white video signal. In order to detect and display such signals, select the rele-
vant standard from the list.

M Series User Manual3-25020-100009-07 Rev. 1 (07-2012)
•Filter: The proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. 
Override only if standard pixel tracking and phase adjustments do not adequately clear up a “noisy” video 
signal, or if a graphics signal appears overly “soft”. Both instances indicate that “Filter” may be set to the 
wrong option.
•Sampling Mode: Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB or YCbCr 
4:2:2. The proper sampling mode is determined automatically by the projector; you can override this setting.
•Film Mode Detect: Enable or disable film motion detection. Only available for interlaced or segmented 
frame sources.
•Chroma/luma Delay: Affects any incoming composite or S-video signal, delaying the luma signal 
(intensity) in relation to the chroma (color). In the image, increasing the luma delay will move luma (seen as 
a shadow where colors overlap) to the right slightly, with colors remaining in place. Decreasing this delay 
will move the shadow slightly to the left. If necessary for your current source, adjust so that no shadows 
occur with adjacent colors.
•Adaptive Contrast: Dynamically expands the contrast of the output image producing vibrant images with 
seamless response to scene changes and fades. The slide bar adjusts the amount of adaptive contrast to apply, 
with a setting of “0” producing no change. Adaptive contrast is disabled when the Dynamic Iris is operating 
in Dynamic mode.
•Split Screen: This control allows a snap shot of the main image to be presented on the right side or lower 
part of the screen, to allow evaluation of advanced image processing features. All resizing controls are 
honoured on both images. However, image processing controls (such as, Detail, Sharpness, Noise Reduction 
and Adaptive Contrast) only happen on the left side or top image. Changing inputs, channels or test patterns 
will disable this control. PIP operation must be disabled prior to enabling this control. 
NOTE: Split screen cannot be used in conjunction with either PIP or Tiling. Both PIP and Tiling must be 
disabled prior to enabling Split Screen control.
•RGB Quantization Range: This control defines the RGB quantization levels for digital DVI and HDMI 
inputs using the RGB colors pace. Typically, graphics sources use the full range of levels for the given bit 
depth (i.e. 8-bit, 10-bit, 12-bit) and consumer electronics (CE) products typically use a limited range of data 
within the given bit depth. This control must be set to limited to correct the levels for those CE products that 
use the limited space. This adjusts what is considered black and white levels in the image. As an example for 
8 bit space, full range RGB uses levels 0(black) to 255(white). Split Screen cannot be used in conjunction 
with either PIP or Tiling. Both PIP and Tiling must be disabled prior to enabling the Split Screen control.

Section 3: Operation
3.6.6 Input Levels - Submenu 
NOTES: 1) Because the projector automatically optimizes input levels for all but the most unusual of sources, 
it is recommended that only experienced users use the Input Levels submenu. 2) Before beginning, check that 
overall contrast and brightness settings are near 50 and that color temperature is properly set up on an 
internal gray scale test pattern. 3) See 3.1.6 Remote Keypad Commands, “AUTO”.
Good RGB or input levels—that is, the drives and black levels for each of the three colors, red, green and 
blue—ensure that images from analog sources other than decoded video have maximum contrast without 
crushing black or white. By default (and in an “Auto Setup”), the projector automatically determines the best 
input levels by monitoring image content and adjusting the controls appropriately. Further adjustment is 
typically not required to obtain proper blacks or whites. 
NOTE: This automatic adjustment requires at least 6-12 consecutive white pixels in the image. Without these 
pixels, input levels may produce skewed colors, particularly in non-video images.
For a source exhibiting overly high black levels (typically caused by a noisy source causing black level spikes) 
use the Input Levels menu (shown above). These adjustments, serve as a calibration process compensating for 
differences in sources and cabling, to perfect the source image input levels and eliminate the “overshoot” and 
“undershoot”. 
NOTES: 1) Input Levels are of limited use with digital signals, but do offer some ability to tweak poorly 
mastered source materials. 2) Input levels apply for the current source only, but for any color temperature 
used. 3) Assuming that color temperature has been set up based on the internal test patterns, you can then set 
up input levels for a given source so that it matches the color temperature of the internal test patterns.
•Auto Input Level: Use only if you are an experienced user and you have an unusual source that you feel 
needs further color temperature and/or input level adjustment. This compensates for incoming out-of-range 
drives (white) and black levels (black) that would cause “crushing” of light and dark colors in the image. 
After entering a check mark, wait for the six slide bar values to stabilize, then delete the check mark and exit. 
The Auto Input Level is automatically turned off upon exit from the Input Levels Menu.
• Black Levels And Drives: 
IMPORTANT! Do not use Input Levels to adjust color temperature. This will distort contrast and brightness 
functions as well as color temperature.
To check your image levels and adjust these controls: 
						

							Section 3: Operation
M Series User Manual3-27020-100009-07 Rev. 1 (07-2012)
1. Ensure overall “Contrast” and “Brightness” settings are both set to near 50. 
NOTE: Not required for “Auto” adjustment.
C
ONTRAST = 50 (approx.)BRIGHT = 50 (approx.)
2. Check the color temperature setup using an internal grey scale test pattern, making sure to obtain a neutral 
grey scale. 
NOTE: Not required for “Auto” adjustment.
3. Confirm that you are using input on an Analog BNC card or a Dual Link DVI card. Input Levels are not 
applicable for sources going through the decoder. A grey scale is recommended.
4. If black levels are too high (and/or whites are too low, which is rare), you likely have a noisy source that is 
producing skewed input levels. Enable “Auto” in the Input Levels menu. Wait for all six values to 
stabilize. Alternatively, do not use “Auto”; reduce black levels manually instead. Judge by eye and change 
one or more of the six levels as necessary to obtain proper blacks and whites. You may want to see only a 
certain color while adjusting; use the Auto Color Enable option (described below).
5. Delete the “Auto” check mark and leave the Input Levels menu.
•Auto Color Enable: When a check mark is present, selecting a specific black level or drive to adjust will 
automatically enable the corresponding color in the display. Delete the check mark to see all colors, or to 
enable a different specific color through the Color Enable control.
•Clamp Location: Brightens the image produced from certain high-resolution high-frequency graphic 
sources. The projector automatically selects the best clamp location for most sources. Use the normal Back 
Porch location if the image is either sufficiently bright or overly bright. Select Sync Tip if the image appears 
unusually dim, if there are horizontal streaks across the image, or if there is significant color drift. This 
moves the clamping pulse from the normal back porch location (which is likely too short) to the tip of the 
horizontal sync pulse. Tri Level is typically needed for an HDTV source.
•Input Peak Detector: A tool to assist with defining individual input levels, enabling you to accurately set 
the Input Levels for any particular source with the appropriate image. Enabling the Peak Detector activates a 
special operating mode for detecting only pixels that are considered black or white—all other levels are 
displayed as a mid-level grey. When used with a smooth grey scale pattern in which black and white are 
known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual 
black levels and input drives until both black and white edges are just visible and distinguished from 
neighboring pixels. Images from this source will then display correct blacks and whites without crushing. 
See Figure 3-8.
1. Display a 16 level grey scale test pattern from the desired external source, and enter a check mark in the 
Input Peak Detector check box. 
NOTE: The Input Peak Detector will initially render the grey scale as a uniform grey field before 
adjustment or extreme crushing.
2. Display one primary color. 
NOTE: Select Auto Color Enable to ensure the correct color is displayed for each setting. 
3. For the current color, adjust its corresponding Black level slide bar just until a single band of black appears 
at one edge of the screen. This band represents the first band of the grey scale pattern, which should be 
100% black.
4. With the same color still active, adjust its corresponding Input Drive slide bar just until a single band of 
color appears at the opposite edge of the screen. This band represents the last band of the grey scale 
pattern, which should be 100% white (or the current color, if a certain color is enabled). 
5. Check the black band and adjust the black level slide bar if necessary. 
NOTE: Adjusting the black levels affects the gain. Only adjust when necessary. 
						

							3-28M Series User Manual020-100009-07 Rev. 1 (07-2012)
Section 3: Operation
6. Repeat Steps 3-5 with the two remaining primary colors. When each primary color shows one optimized 
black band and white (or colored) band, the input levels for this source are correctly set. Upon exiting the 
Input Levels menu, the Peak Detector check box will clear.
•Color Enable: Select which color or colors you want to see in the display, useful while working with color 
temperature white levels or input levels. 
NOTES: 1) Input levels apply for the current source only, but for any color temperature used. 2) If color 
temperature is set up based on the internal test patterns, you can set up input levels for a given source so that 
it matches the color temperature of the internal test patterns.
3.6.7 Advanced Image Settings - Submenu
Use the Advanced Image Settings submenu to make the adjustments necessary for lesser-used but more 
specialized applications on your projector.
3.6.8 Gamma Settings - Submenu
The system offers two types of gamma correction. Gamma correction can be applied to a specific source to 
correct for luma encoding. This is a channel setting and reapplied every time the same signal is detected. This 
is the Gamma control. On the other hand the system also provides a global Gamma Correction control. The 
global control offers an offset applied to all channels. This offset is used to compensate for changes in ambient 
conditions such as ambient light in the room and projected material.
•Gamma Settings: The system offers two types of gamma correction. Gamma correction can be applied to a 
specific source to correct for luma encoding. This is a channel setting and reapplied every time the same 
signal is detected. This is the Gamma control. On the other hand the system also provides a global Gamma 
Correction control. The global control offers an offset applied to all channels. This offset is used to 
compensate for changes in ambient conditions such as ambient light in the room and projected material. 
•Gamma Correction: Applies a global offset to all gamma settings for each channel. It affects the shape of 
the curve by performing a linear transform toward a gamma curve of 1.0 while the control is increasing and 
likewise a linear transform toward a gamma of 3.0 as the control is decreasing. The control should only be 
adjusted to compensate for ambient conditions. To correct a particular source only, use the Gamma control.
