• Select “FULL SCREEN”  to use all pixels (1280 x 1024 in
S12) for displaying the image, regardless of source or
original aspect ratio. See right. NOTE: Shown with S12
resolution. Roadie X10 has 1024 x 768 resolution.
• Select 
“FULL WIDTH” to fill the display from left-to-
right. Depending on the source, this may create top
and bottom borders. See right.
• Select 
“FULL HEIGHT” to fill the display from top-to-
bottom. Depending on the source, this may create
side borders. See right.
• Select
 “ANAMORPHIC” to display an entire non-HDTV
“wide screen” (anamorphic) image in its native 16:9
aspect ratio. Known as letterbox, the image will fill the
screen from left-to-right, but will not use all vertical
pixels available (top and bottom will be black). If you
do not choose “Anamorphic” when a non-HDTV
anamorphic image is present, the default image will be
stretched vertically, characterized by obvious distortion
and “thin people”.
NOTE: Use “Anamorphic” for regaining a 16:9 display of non-HDTV
anamorphic sources only (common to some DVDs, for example). For HDTV, the
“Default” setting will produce the same result.
• All 
TILED resizing choices are selectable only if you have defined a tiled group of
projectors in the Tiling Setup submenu. See 3.10, Using Multiple Projectors.
Size
Size controls both the image width and height in tandem, maintaining the original
aspect ratio (proportion) of data from the incoming signal. Under some conditions in
the X10, adjusting size also adjusts keystone.
NOTE: If Size 
$1000 (1000 = No Resizing) and Size x Vertical Stretch value
$1,000,000, adjusting Size also adjusts keystone simultaneously.

Vertical Stretch
Vertical stretch adjusts the height the image while keeping the width constant. Use
Vertical Stretch to display data from the incoming signal in a different aspect ratio.
Under some conditions, adjusting Vertical Stretch also adjusts keystone.
NOTE: If Size 
$1000 (1000 = No Resizing) and Size x Vertical Stretch value
$1,000,000, adjusting Vertical Stretch also simultaneously adjusts X10 keystone.
Pixel Track
(
SHORT CUT: Press Pixel and adjust the top slidebar.)
Pixel tracking adjusts the frequency of the pixel sampling clock, indicated by the
number of pixels per line, so that all pixels generated by a particular source are
sampled. Proper pixel tracking ensures that the image quality–whether good or poor–
is consistent across the screen, that aspect ratio is correct, and that pixel phase can be
optimized (below).
NOTE: By default, the projector samples at the correct frequency for most sources.
Pixel tracking is adjusted most effectively using a good test pattern, such as a smooth
gray consisting of a clear pattern of tiny black and white dots, or a similar “half on,
half off” graphic image, such as the Windows shutdown screen. Steady flickering or
several soft vertical stripes or bands across the entire image indicates poor pixel
tracking. Adjust the slidebar until the stripes broaden to the point where one large
stripe fills the image. Again, the image may still exhibit some noise. See Pixel Phase.
Pixel Phase
(
SHORT CUT: Press Pixel and adjust the bottom slidebar.)
Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming
signal. It is used primarily for adjusting RGB inputs.
NOTE: Adjust pixel phase after pixel tracking is properly set.
Adjust pixel phase when the image (usually from an RGB source) shows shimmer or
“noise”. Pixel phase adjustment is done most effectively from within a proper test
pattern, such as a smooth gray consisting of a clear pattern of tiny black and white
dots, or a similar graphic image, such as the Windows shutdown screen. Adjust until
the image is stable and each dot is clearly defined. Using the numbers on the slidebar
as a guide, you will notice that you can actually 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 select either setting.
Filter
Filter applies a low pass filter to the input signal. This removes high frequencies
which can improve pixel phase noise but which also reduces signal bandwidth. Note
that most signals will not require any filter adjustment—use the filter option only if
standard pixel tracking and phase adjustments do not adequately clear up a “noisy”
signal. For best results:

1. Optimize Pixel Tracking and jot down the
value.
2. Optimize Pixel Phase
3. If the image is still too noisy, return to Pixel
Tracking and “mis-adjust” so that 2 vertical
bands of noise appear, separated by a good
center band. See right.
4. Adjust Filter to maximize the width of the good
area. See right.
5. Return Pixel Tracking to its correct setting from
Step 1.
6. Readjust Phase.
NOTE: “Filter” affects only the current signal.
H-Position
(
SHORT CUT: Press Pos it ion and adjust the top slidebar.)
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
(
SHORT CUT: Press Pos it ion and adjust the bottom slidebar.)
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.
Lens Control
(
SHORT CUT: Press Lens to activate the Lens Control menu.)
For a full description of the Lens Control menu, see 3.3, Using the Keypad (
Lens key)
and 2.8, Zoom, Focus & Lens Offset.
Blanking: Top, Bottom, Left or Right
This submenu blanks (turns to black) the top, bottom,
left, or right edge of the image so that any unwanted
information is cropped from view. For example, when
displaying native size video you may want to blank out
a few of the top lines. Avoid using in combination
with “Keystone” option.
PLL Loop Gain
This control changes the relative offset to the default gain. The default PLL (Phase
Lock Loop) Loop Gain setting of 10 is set automatically with a Pixel Tracking

Roadie S12/X10 User’s Manual3-29
adjustment and is correct in most cases. In rare instances, such as if your image
exhibits tearing or “flag-waving”, increase the PLL loop gain setting as necessary.
Or, if your image is unstable and “breaks up”, this may indicate that the PLL loop
gain setting is either too high or too low. PLL Loop Gain affects the current channel
only.
Keystone
NOTE: Optimized in X10 only.
Adjust the keystone control if Roadie X10 images appear keystoned in shape—that is,
smaller at either the top or bottom rather than rectangular. The effect of keystone
adjustment is similar to physically tilting the projector up or down in relation to the
screen, and it affects all sources.
NOTES: 1) Keystone is enabled for a source only if  Size is 
$1000 and Size x Vertical
Stretch is 
$1,000,000. 2) Optimized in X10 only. 3) Avoid using Keystone with
Blanking.
Generally, set at 50 (default) to apply no
keystone—if your projector is positioned
with its lens surface parallel to the screen,
images will be rectangular. If images are
too narrow at the bottom, increase
keystone. If images are too narrow at the
top, reduce keystone.
The keystone control may be limited
when Size is just slightly greater than
1000. In general, work with image size,
stretch and keystone controls as necessary for your application.
Plug & Display (EDID)
By default, the Plug & Play option detects an incoming
digital flat panel video signal and displays it in the native
resolution of your projector. If you have additional daisy-
chained projectors, they will display in this resolution as
well. If you want to use a different resolution (for example,
your graphics card may not support the current resolution),
select a different Plug & Play setting from the list—XGA (10240x 768), SXGA
(1280 x 1024) OR UXGA (1600 x 1200).
Tiling Setup
See 3.10, Using Multiple Projectors (Tiling Setup section).

Roadie S12/X10 User’s Manual
Use options in the two-page Image
Settings menu to alter your image in
ways that do not affect its size or
position. Changes made to the Image
Settings menu are applied
immediately and are saved when you
exit the menu (press 
Exi t or Menu).
Options not available for your
projector appear dim and are disabled.
Contrast
(
SHORT CUT: Press Cont and adjust the
slidebar.)
“Contrast” increases or decreases the
perceived difference between light
and dark areas of your image (0-100).
If contrast is set too high, the light
parts of the image lose detail and
clarity. If set too low, the light areas
will not be as bright as they could be
and the image will be dim. Start low
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”). For best results, keep close to 50.
NOTE:  If environment lighting changes, it may be necessary to re-adjust both
options.
Brightness
(
SHORT CUT: Press Bright and adjust the slidebar.)
“Brightness” increases or decreases the amount of black in the image (0-100). Start
high 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.
For best results, keep close to 50.
Pixel Phase
(SHORT CUT: Press Pixel and adjust the slidebar.)
See description in Size and Position section, above.
Detail
(
SHORT CUT: Press  and adjust the slidebar.)
”Detail” adjusts the sharpness of a video image. Use 
 and  until the display
is as sharp as desired, keeping in mind that any increase in detail above 3 (default)
will also introduce a certain degree of noise in the image. Set below 3 to filter the
signal and remove noise from a noisy source. Keep at 3 to apply no detail. Ima

Color Space
This option determines how the color components of an input signal are decoded for
accurate color in the display. Selecting a color space option is useful only for analog
signals connected to 
INPUT 1 or INPUT 2. Although the color space for such a signal is
automatically determined by the projector, in some circumstances you may wish to
override this and manually set a different color space.
NOTE: For digital signals or for signals connected to 
INPUT 3 or INPUT 4, the color
space function is entirely automatic and the pull-down list disabled.
The current color space appears in the Image Settings menu. Press 
 to select a
different option:
• Select 
RGB unless you are using component video at INPUT 1 or 2.
• 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 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, then define a new channel for
future use.
Color Setup
Select this submenu to work with
aspects of color—adjust for
saturation and overall hue in video
signals, or adjust gamma or
temperature in any display.
COLOR — “Color” adjusts the
color saturation level or the
amount of color in a video image. When set to “0’ the image appears black and
white, and when set too high the colors appear overpowering and unrealistic. Use
 and  to adjust “Color” until the desired saturation level is displayed. For a
shortcut to “Color” slidebar, press 
Color at any time.
TINT — “Tint” adjusts color hue to obtain true color reproduction of NTSC video
signals or HDTV signals. Use 
 and  until the desired balance or red-to-green
is displayed in your image. It is best to adjust tint while displaying an external test
pattern—otherwise, it is recommended that tint remain at its default setting. For a
shortcut to “Tint” slidebar, press 
Tint at any time.

Roadie S12/X10 User’s Manual
SELECT COLOR TEMP —  “Select Color Temp” applies either a
preset color temperature (3200K, 5400K, 6500K or 9300K) or
any previously “User” defined color temperature. Color
temperatures are measured in degrees Kelvin and represent the
“coloration” (reddish or bluish) of the whites displayed by the
projector—the lower the temperature, the more reddish the
whites; the higher the temperature, the more bluish the whites.
NOTE: The custom temperatures “User” or “Interpolated
Color” all default to 6500K until they are redefined in the
Color Temperature Setup menu. See below.
INTERPOLATED COLOR — Use this option if you need a specific color temperature
that lies somewhere between one preset color temperature and another. Adjust the
slidebar to define a new temperature which will be interpolated from the neighboring
presets (for example, 7841 is interpolated from 6500 and 9300). This slidebar is
disabled unless you have a source connected and have selected “Interpolated Color”
in the “Select Color Temp” pull-down list.
GAMMA — NOTE: Gamma does not normally require adjustment and is intended for
experienced users only.
The Gamma option affects the shape of the curve determining
what gray shades are available for a given amount of signal
input between minimum (black) and maximum (white).
Different curves can improve performance for certain kinds of
source input and applications. Generally the best gamma curve
is one that produces maximum contrast, brightness and color
performance for the current signal and ambient lighting
conditions.
DEFAULT (default) –  This setting provides good black levels and high contrast
under optimum viewing conditions for virtually all types of images, including
video, HDTV and computer graphics.
ENHANCED – This setting elevates middle gray levels compared to “Default”, and
provides a more gradual rolled-off transition to maximum white. Together, these
differences can improve the appearance of many kinds of images.
HIGH AMBIENT – This setting elevates low gray levels compared to the “Default”
and “Enhanced” settings. In high ambient light conditions, details can be seen in
the dark parts of an image that would otherwise be difficult to perceive.
PAL/SECAM – This setting results in a darker image with higher contrast. The
gamma curve more closely matches the official standard for PAL and SECAM
video signals.
LINEAR – This setting is a straight, linear transition from black to white. For
normal source signals, it results in a picture of low contrast with highly elevated
low- and mid- level grays. It should be used only with sources that have their
own pre-applied gamma control.
COLOR TEMPERATURE SETUP —  Use the Color Temperature Setup submenu to
apply, alter, add, or copy a color temperature, or if you want to use an unaltered
factory default color temperature.. This menu is duplicated in other locations. 
						

							OPERATION
Roadie S12/X10 User’s Manual3-33
By default, the projector can utilize any of four calibrated factory-set color
temperatures: 3200, 5400, 6500 or 9300 (expressed in degrees Kelvin). For most
applications, these temperatures will display accurate and realistic colors from a
variety of sources. They can be selected at any time from the “Select Color Temp”
list in the Color Setup submenu.
However, if you require extra color temperatures, you can also add up to five custom
color temperatures—four “User” and one “Interpolated Color”—by defining them
within the Color Temperature Setup menu (each defaults to 6500K until then). Any
“User” or “Interpolated Color” temperature created here is immediately applied, or it
can be selected at any time from the Color Setup menu as usual, regardless of your
source or channel. Use of the Color Temperature Setup menu is described below.
NOTE: For best results, use an internal grayscale test pattern when working with
color temperature.
Figure 3.15. Color Temperature Setup Menu
SELECT COLOR TEMP – See Figure 3.15. Upon opening the Color Temperature
Setup menu, the current temperature appears as the top option. You can change to
a different color temperature here as desired, just as in the Image Settings menu.
Note that selecting a “User” color temperature, enables the “White Level”
options in the Color Temperature Setup—adjust as desired to define or change a
“User” color temperature (see “White Levels”, below). Likewise, selecting
“Interpolated Color” here activates the “Interpolated Color” slidebar for choosing
a new interpolated color temperature for a connected source.
INTERPOLATED COLOR – Select this option if you need a specific color
temperature that lies somewhere between one preset color temperature and
another. Adjust the slidebar to define a new temperature which will be
interpolated from the neighboring presets (for example, 7841 is interpolated from
6500 and 9300). It can be used any time and appears as a 4-digit temperature
when in use. NOTE: This option is disabled unless you have a source connected
and have selected “Interpolated Color” in the “Select Color Temp” pull-down
list.
WHITE LEVELS –These 3 controls are adjustable only if a “User” choice is
selected (in which case “User 1, 2, 3 or 4” appears at the top of the Color
Temperature Setup menu). Their current values are shown for the active color
temperature. Changing a white level here changes the drive (contrast) for that
color, essentially creating a new color temperature that is “warmer” or “cooler” 
						

							OPERATION

Roadie S12/X10 User’s Manual
etc. For maximum overall brightness, always keep at least one white level at
100. When you are satisfied with the new “User” temperature, it can be used
immediately upon exit or it can be selected from either the Image Settings menu
or the Color Temperature Setup menu as usual. You can re-define a “User” color
temperature at any time using the Color Temperature Setup menu.
COLOR ENABLE – Select which color or colors you want to see, useful while
working with color temperature white levels.
COPY FROM – Use this option to replace the currently selected “User” color
temperature setup with that of another. This function can be particularly useful as
a starting point for a new “User” color, or for accessing an unaltered factory
default. It is disabled for all color temperatures except “User”. See Figure 3.16.
Figure 3.16. “Copy From”
To create a starting point: To set a starting point for a new custom user color
temperature, select a user temperature, then highlight “Copy From” and select a
temperature similar to what you want. Adjust white levels from there as desired.
To use a factory default: The preset
color temperature setups (3200K,
5400K, 6500K and 9300K) can be
altered from within the password-
protected Service menu only—note that
although such an alteration changes the
setup and appearance for a preset, it
does not change its name. If you suspect
that you are using a preset temperature
that has been altered and you want
instead to use the original factory-
calibrated color temperature without
clearing the entire projector memory,
you can use the “Copy From” option in
the Color Temperature Setup menu to set
up a “User” temperature with settings from a permanent factory preset:
1. Select the “User” color temperature you wish to update at the top of the Color
Temperature Setup menu, such as “User 2”.
Figure 3.17. Presets and
“Factory” Presets 
						

							OPERATION
Roadie S12/X10 User’s Manual3-35
2. From the “Copy From” list, select the matching temperature labeled “Factory”
(such as “Factory 5400K”). These are the calibrated color temperatures set at
manufacture—they remain intact for the life of the projector.
3. The setups for the “User” color temperature you selected at the top of the
Color Temperature Setup menu will now be updated/replaced by those for the
permanent factory calibrated temperature you selected in the “Copy From”
list. Again, a “User” temperature can be altered at any time, if desired.
Video Options
Not applicable with graphics sources.
VIDEO STANDARD — The projector
automatically detects the video standard
present and displays the name of this
standard here. Press 
 to view or
select a different video standard from a
complete list available to the projector
(some will appear disabled, depending on the current incoming signal). Selecting a
specific standard forces the projector to process the signal according to this standard.
NOTE: This option should remain set at “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.
INPUT VIDEO BLACK — This control compensates for incoming elevated black levels–
called “setup”–that are present in certain video signals, and ensures that blacks on
screen are neither crushed (i.e., with dark gray appearing black) nor excessively
elevated (i.e., with black appearing dark gray). By default, the projector automatically
determines the correct setting according to the type of incoming video signal:
• 
0 IRE – For DVD output with “enhanced black”, SECAM, most PAL
standards, and Japanese NTSC.
• 
7.5 IRE – 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”.
VCR – This control determines to what degree the projector tolerates signal
disturbances. The correct setting is automatically determined and set according to the
type of incoming source signal–for instance, there should be a checkmark for all
VCR sources. The VCR option may require a change from its auto setting in very
rare circumstances only, such as if you are having difficulty switching between two
unusual and almost identical VGA computer sources. Otherwise, it is not necessary
to change this option.
VIDEO TERMINATION — Enter a checkmark
to terminate the video inputs 3 and 4 (75
S). The input should be terminated unless
the signal loops through (continues) to
another projector or display device, in
which case only the last projector in the
chain should be terminated.
