 Anamorphic Option
•Select Anamorphic to display an incoming Cinema scope signal in a 16:9 aspect ratio without the use of 
an anamorphic lens mount. The image fills the screen from top-to-bottom, and be centered between 
narrow black bars on each side. 
Size Option
Select the Size option from the Size and Position menu. Size controls both the image width and height in 
tandem, maintaining the current aspect ratio (proportion) of the displayed signal data.
Vertical Stretch Option
Select the Vertical Stretch option from the Size and Position menu. Vertical stretch adjusts the height of the 
image while keeping the width constant. Use Vertical Stretch to change the aspect ratio of the display.
Pixel Track Option
Select the Pixel Track option from the Size and Position menu. Steady flickering or several soft vertical 
stripes or bands across the entire image indicates poor pixel tracking. Proper pixel tracking helps ensure that 
the image quality is consistent across the screen, that aspect ratio is maintained, and that 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 good test pattern such as a smooth gray consisting of a clear pattern of black and white 
pixels, or a similar half on, half off graphic image, such as the Windows shutdown screen. Adjust the 
slidebar 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 the Pixel Phase described next.
Pixel Phase Option
NOTE: Adjust Pixel Phase after Pixel Tracking.
Select the Pixel Phase option from the Size and Position menu. 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.

Section 3: Operation
For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white 
pixels, or a similar half on, half off graphic image, such as the Windows shutdown screen. Adjust the slidebar 
until the image stabilizes and each pixel is clearly defined. You may notice that you can stabilize the image at 
more than one point-i.e., you may find that the image appearance at 11 is identical to the image appearance at 
38, thus you can use either setting.
If some shimmer from a video or HDTV source persists, use the Filter control to remove high-frequency 
noise from the signal.
H-Position Option
Select the H-Position option from the Size and Position menu. This option 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.
V-Position Option
Select the V-Position option from the Size and Position menu. This option moves the image up or down 
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 vertically. This varies widely according to the signal-watch the image while adjusting.
Advanced Size and Position Secondary Menu
This secondary menu consists of the following options:

Active Input Window Option
Select the Active Input Window option from the Advanced Size and Position menu. This read-only parameter 
indicates the current size (i.e., area) of your displayed data or region of interest as defined by the blanking 
controls. For example, if you have blanked (cropped) 100 pixels from both the left and right edges of an 
incoming source of 2048 x 1080, the remaining active input window is 1848 x 1080. When using a video 
source at INPUT 3 or INPUT 4, the default blanking of  0 defines an active input window of 720 x 483for 
NTSC video.

Blanking (Top, Bottom, Left, and Right) Options
Select a Blanking option from the Advanced Size and 
Position
 menu. Crop the image as desired so that unwanted 
edges are removed from the display (changed to black as shown 
in Figure 3-16
). Blanking defines the size of the Active Input 
window, creating an area of interest. Range of adjustment 
depends on the source resolution and other factors for your 
application. 
NOTE:  Blanking a PIP image resembles zoom (refer to Figure 3-
31). For example, left Blanking zooms the right side of the 
PIP image; Right Blanking zooms the left side. There are 
no black bars. 
Plug & Display (EDID) Option
Select the Plug & Play option from the Advanced Size and Position 
menu. By default, a 
Plug & Play (EDID) source outputs a signal 
according to the EDID information provided by the projector. To override 
this information and display in a different format (for example, if your 
Plug & Play [EDID] device does not support the projectors resolution 
and/or frequency), select the desired 
Plug & Play (EDID) resolution 
from the list.
Any daisy-chained projectors also displays according to the chosen Plug 
& Play (EDID) format.
EDID = Extended Display Identification Data standard.
3.6.3 Image Settings Menu
Select the Image Settings (#2 option) from the Main menu.  Options in the Image Settings menu alter your 
image without affecting its size or position. Changes made to the 
Image Settings menu are applied 
immediately and are saved when you exit the menu. Options not available for the projector model or source are 
disabled and appear dim (gray).

Section 3: Operation
Contrast Option
Short Cut: Press CONT on the standard IR remote and adjust the Contract slidebar in the menu.
Select 
Contrast from the Image Settings menu. Contrast increases or decreases the perceived difference 
between light and dark areas of your image (0-100). For best results, keep close to 50. If the contrast is set too 
high, the light parts of the image lose detail and clarity. If the contrast set too low, the light areas will not be as 
bright as they could be, and the overall image will be dim. For best results, start with a low value and increase 
so that whites remain bright , but are not distorted or tinted, and that light areas do not become white (i.e., are 
crushed). 
NOTE:   If the environment lighting changes, an adjustment of Gamma is recommended (see below).
Brightness Option
Short Cut: Press BRIGHT on the standard IR remote and adjust the Brightness slidebar in the menu.
Select 
Brightness from the Image Settings menu. 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 (i.e., are crushed). Conversely, high brightness changes black to dark gray, causing 
washed-out images. 
NOTE:  Brightness affects contrast, and should be adjusted first.
Gamma Option
Short Cut: Press GAMMA on the standard IR remote and adjust the 
Gamma slidebar in the menu.
Select 
Gamma from the Image Settings menu. Gamma is a 
global setting that determines what gray shades are displayed 
between minimum input (black) and maximum input (white) for 
all signals. A good gamma setting helps to optimize blacks and 
whites while ensuring smooth transitions for the in-between values utilized in other colors. 
Thus, unlike brightness and contrast settings controls, the overall tone of your images can be lightened or 
darkened without changing the extremes, and all images display more vibrantly while still showing good detail 
in dark areas.
Gamma fine-tunes the gamma table currently in use, ranging from 1- 3 (default = 2.2, indicating that the 
chosen gamma table has not been adjusted). If excess ambient light washes out the image and it becomes 
difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This  improves 
contrast while maintaining good details for blacks. Conversely, if the image is unnatural with excessive detail 
in black areas, increase the setting. For more information, refer to the Gamma Table
 and Figure 3-29.  Again, 
look for good contrast and good details in very dark areas.
Filter Option
Select Filter from the Image Settings menu. The proper Filter setting is automatically 
set for virtually all signals, and rarely needs to be changed.  It applies a low pass filter for 
noise reduction in the incoming input signal, particularly for HDTV or SDTV. Applied in 
the analog domain before sampling, this filtering removes high frequencies and thus 
reduces pixel phase noise (note this also reduces signal bandwidth). 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. 
						

							Section 3: Operation
Roadie HD+35K User Manual3-29020-100340-02 Rev. 1  (01-2010)
Detail Option
Select Detail  from the Image Settings menu. Detail adjusts the sharpness of a video image so that edges 
remain clearly defined. It can be particularly useful if a significant Noise Reduction adjustment has caused 
the image to appear too soft. Adjust until the display is as sharp as desired, keeping in mind that because 
Detail adds some high frequencies back into the image, it can also re-introduce a certain degree of noise.
Noise Reduction Option
Select Noise Reduction from the Image Settings menu. Noise reduction is similar to the Filter control, but 
operates in the post-sampling digital domain with a more subtle effect. Higher settings are most useful for 
clearing up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind that reducing noise 
(which reduces high frequencies) may also soften the image.
Color Space Option
Select Color Space from the Image Settings menu. Color Space determines how the 
color components of an analog input signal or certain digital signals connected to
 
INPUT 1, INPUT 2, INPUT 5, or INPUT 6 are decoded for accurate color in the 
display. Although color space for these analog signals is automatically determined by 
the projector, in some circumstances you may wish to override this and manually set a 
specific color space.
NOTE: For most digital signals or for signals connected to INPUT 3 or INPUT 4, the color space function is 
entirely automatic and the drop-down list disabled.
The current color space appears in the Image Settings menu. Press ENTER to select a different option:
•Select RGB unless you are using component video at INPUT 1, 2, 5, or  6.
•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 initially recognize them as RGB and  
incorrectly decodes 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, then define a new channel for future use.
Video Options Secondary Menu
Select Video Options from the Image Settings menu. This secondary menu is used with video sources only 
(Inputs 3 or 4).
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.
Enable Decoder AGC  Option
Select Enable Decoder AGC from the Video Options menu. Automatic Gain Control (AGC) affects 
decoded video images only. Enter a check mark (default) in most instances to activate the decoders AGC 
circuit and 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.

Section 3: Operation
Video Standard  Option
Select Video Staandard from the Video Options menu. With the exception of the more unusual video 
standards available in the world, the projector automatically detects the incoming horizontal and vertical 
frequencies and sets the projectors processing of this signal to the corresponding standard. The current video 
standard name appears in the 
Video Options secondary menu, and includes an A if it has been auto-detected. 
Press 
ENTER 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:  Generally, use Auto for all instances EXCEPT: 1) a poor quality input signal or 2) a black-and-white 
video signal. In order to detect and display such signals, select the relevant standard from the list.
Input Video Black  Option
Select Input Video Black from the Video Options menu. 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 grays appear black) nor 
excessively elevated (i.e., where blacks appear dark gray). 
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  Option
Select Color from the Video Options menu. This slidebar adjusts the color saturation level, i.e. the amount of 
color in a video image. 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 Option
Select Ti n t from the Video Options menu. This slidebar adjusts the red/green color hue for true color 
reproduction of video and HDTV signals connected to Input 3 or 4. For best results, adjust the tint while 
displaying an external test pattern-otherwise, it is recommended that tint remain at its default setting.

Decoder Luma Delay  Option
Select Decoder Luma Delay from the Video Options menu. This control 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 moves luma (seen as a shadow where colors overlap) to the right slightly, with colors remaining 
in place. Decreasing this delay moves the shadow slightly to the left. If necessary for your current source, 
adjust so that no shadows occur with adjacent colors.
Input Levels Option Menu
Select Input Levels from the Image Settings menu. 
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 secondary menu.
 2) Before beginning, 
check that overall contrast and brightness settings are near 50 and that color temperature is properly set 
up on an internal grayscale test pattern.
 3) There must be at least 6-12 consecutive white pixels present in 
the image for proper Auto Input Level function. Leave this control off after use.  
Good RGB or input levels (that is, the drives and blacklevels 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.  It is not necessarty to make  
further adjustments 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.
However, for a very unusual source exhibiting one or more overly high blacklevels (typically caused by a 
noisy source causing blacklevel spikes), an experienced user may prefer to use the Input Levels menu (shown 
above). These adjustments, which together serve as a calibration process compensating for differences in 
sources and cabling, enable an experienced user to perfect the source image input levels and eliminate the 
overshoot and undershoot. 
NOTE:  Input Levels are of limited use with digital signals, but do offer some ability to tweak poorly mastered 
source materials.
Auto Input Level
Select Auto Input Level from the Input Levels menu. Keep OFF for virtually all sources (default). If you are 
an experienced user, you can temporarily select the  check box if you have an unusual input source that you 
feel needs further color temperature and/or input level adjustment. This compensates for incoming out-of-
range drives (white) and blacklevels (black) that would cause crushing of light and dark colors in the image. 
Once the six slidebar values stabilize, clear the check box, and 
EXIT. The Auto Input Level should be 
automatically turned OFF (check box cleared) upon exit.
Blacklevels and Drives
To check your image and adjust these controls:
1. Make sure overall Contrast and Brightness are both set to near 50. 
• 
CONT = 50 (approx.)
• 
BRIGHT = 50 (approx.)
NOTE:  Not required for Auto adjustment.
2. Check the color temperature setup using an internal grayscale test pattern, making sure to obtain a neutral 
grayscale.  
						

							3-32Roadie HD+35K User Manual020-100340-02 Rev. 1   (01-2010)
Section 3: Operation
NOTE: Not required for Auto adjustment.
3. Confirm that you are using an analog source not connected to INPUT 3 or INPUT 4, as input levels are 
not applicable for digital sources or sources going through the decoder. A grayscale is recommended.
4. If the blacks and/or whites appear OK, input levels do not need adjustment. 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. Continue with Step 5.
5. Temporarily enable 
Auto in the Input Levels secondary menu. Wait for all 6 values to stabilize. 
Alternatively, do not use Auto, but reduce blacklevels 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 by using the 
Auto Color Enable option (described below).
6. Delete the Auto check mark and leave the 
Input Levels menu.
IMPORTANT! Do not use Input Levels to adjust color temperature. This distorts the Contrast and Brightness
functions, as well as color temperature.
Auto Color Enable 
When a check mark is present, selecting a specific blacklevel or drive to adjust automatically enables the 
corresponding color in the display.  Remove the check mark to see all colors, or to enable a different specific 
color through the 
Color Enable Control.
Clamp Location
This option (formerly known as “sync tip clamping”) can brighten the image produced 
from certain high-resolution high-frequency graphic sources. For almost all sources, the 
projector automatically selects the best clamp location. 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 backporch location (which is likely too short) to the tip 
of the horizontal sync pulse. Tri Level is typically recommended for an HDTV source, where the back porch is 
also short.
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.
Peak Detector
The Peak Detector is a fast method for defining individual input levels, and can improve the accuracy of input 
levels set by the Auto Input level function. 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 gray. 
When used with a smooth grayscale 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 blacklevels and input drives until both 
black and white edges are just visible and distinguished from neighboring pixels. Images from this source then 
displays correct blacks and whites without crushing or washing out. Refer to Figure 3-18
.
1. Display a 16-level grayscale test pattern from the desired external source, and select the Peak Detector 
check box. 
NOTE:  The Peak Detector initially renders the grayscale as a uniform gray field before adjustment.
2. Display one primary color (use the Color Enable option to automatically select as you go).

Roadie HD+35K User Manual3-33020-100340-02 Rev. 1  (01-2010)
3. For the current color, adjust its corresponding Blacklevel slidebar just until a single band of black 
appears at one edge of the screen. This band represents the first band of the grayscale pattern, which 
should be 100% black. Do not adjust too far.
4. With the same color still active, adjust its corresponding Input Drive slidebar just until a single band of 
color appears at the opposite edge of the screen. This band represents the last band of the grayscale pattern, 
which should be 100% white (or the current color, if a certain color is enabled). Do not adjust too far.
5. It may be advantageous to go back and check the black band. You can adjust the blacklevel using the 
slidebar if necessary. 
NOTE: Re-adjusting blacklevels at this point affects the gain; only re-adjust if absolutely necessary. Adjust until 
both bands are just optimized.
6. Repeat Steps 2-5 with the other 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 is cleared.

Gamma Table
This control applies a default video, graphics or simple gamma table or curve to your images, controlling the 
intensity of midlevel colors and producing maximum contrast, brightness and color performance. 
As shown at right, the graphics curve is a simple power curve while 
the video curve has a linear segment near black to compensate for 
increased blacklevels typical of video signals. A simple gamma 
curve is a value of 2.2 and is correct for most signal conditions. 
Although the projector automatically applies either the graphics or 
video curve according to what type of incoming signal is detected, 
in some cases you may wish to override this default and use 
graphics gamma for a video source or video gamma for a graphics 
source.  
						

							3-34Roadie HD+35K User Manual020-100340-02 Rev. 1   (01-2010)
Section 3: Operation
Alternatively, if neither default is ideal, you may prefer to apply the simple (non-optimized) gamma curve or a 
user-defined custom gamma curve that has been created externally, named, and downloaded to the projector 
(requires separate PC-based Arbitrary Gamma and KoRE Librarian software applications). If any of these 
special user curves have been installed, their names appear in the Gamma Table
 drop-down list.
Keep in mind that any Gamma Table choice sets the related Gamma value (shown in the 
Image Settings 
menu) to a 2.2 default, where it can be fine-tuned as desired. Different values (1-3) here indicate that the 
original gamma table has been adjusted with either the Gamma slidebar or direct key.
Select Color Adjustment
In Select Color Adjustment, choose an overall color performance for all images. The Max Drives factory 
default simply drives all 3 colors at their maximum level so that they are fully on and cannot be changed. The 
two other pre-defined color adjustment choices-SD Video and HD Video-apply a color gamut optimized for 
video sources (standard or high-definition). Alternatively, you can specify a color temperature, which enables 
the nearby Color Temperature slidebar and applies its current setting (default = 6500K). 
If none of the pre-defined Select Color Adjustment options or color temperatures suit your application, select 
one of four color gamuts previously defined by a user (User 1, 2, 3, 4). A User option applies a customized 
color performance in which the user has precisely set the hue and intensity of each color component in the 
Color Adjustment by X/Y or Color Saturation secondary menus, and is most often needed with multiple-
projector applications. Select the color adjustment producing the best color accuracy for your application and 
installation.
To configure a User color adjustment (gamut), use either the Color Adjustment by X/Y or Color Saturation 
secondary menu. 
NOTES: 1) Color Temperature defaults to 6500K until changed. All four User options default to SD Video 
unless the user has redefined them. 
2) Factory-defined color primaries, which ensure consistent color 
gamut from projector-to-projector, can be altered in the Service menu only. If you suspect alteration, the 
factory settings can be recovered with selection of Reset to Factory Defaults? in the Service menu 
(password-protected).
Color Temperature
Adjust to apply a specific color temperature to all displays. Color temperatures are expressed in degrees Kelvin 
(3200-9300K), and utilize different combinations of the projectors original native color primaries to produce a 
coloration or cast (reddish or bluish) in images-the lower the temperature, the more reddish the cast; the 
higher the temperature, the more bluish the cast. 
NOTE:  The slidebar is only enabled if you have a source connected, and have selected Color Temperature in the 
adjacent Select Color Adjustment drop-down list in the Advanced Image Settings menu.

From the Advanced Image Settings menu, use the Simulation 3D secondary menu options to make timing 
adjustments for realistic simulation environments.
Frame Delay Monitor
This slidebar monitors the latency between input and output. For best results, the bar width and value should 
remain fairly constant, indicating that timing of input and output frames is locked; the Frame Delay Monitor 
value should stay within 5-10 lines or so of the Frame Delay setting. If a frame is lost or dropped, the slidebar 
moves suddenly and the values change, indicating that the frame input is no longer equal to the output.
