PIP Size and Position – 
SUBMENU 
Most controls in the PIP Size and 
Position menu adjust the PIP 
(secondary) image in the same 
fashion as their counterparts in the 
main Size and Position menu adjust 
the main image—see 3.6, Adjusting 
the Image for details. Exceptions 
are: 
POSITION PRESETS –Set the location 
of the PIP (secondary) image in the display. 
ASPECT RATIO PRESETS – Choose the desired aspect ratio for your PIP window. A 
“Default” aspect ratio matches that of the projector, whereas “Anamorphic” will be a 
widescreen window. Choose according to your incoming source material. 
PIP Image Settings — 
SUBMENU 
Adjust the PIP (secondary image) without affecting the size or position. The primary 
image remains unchanged. See 3.6, Adjusting the Image for details 
PIP Border Width 
Set the desired line thickness for your PIP window border.  
PIP Border Color 
Select the desired color for the PIP window border.  
NOTES: 1) Numbers 7 and 8 on the Picture-in-Picture and Switching submenu 
control switching parameters. 2) Disable PIP in order to work with Seamless 
Switching. 3) Disable PIP and Best Switching for Interlaced sources > 35kHz. 
Seamless Switching is the ability to instantly and/or smoothly switch sources, and is 
controlled with options 7 and 8 in the PIP and Switching menu. To use Seamless 
Switching, PIP must be disabled. 
Tips for best source switching:
 
• Make sure a channel has been configured for each source. 
• Progressive digital and analog sources are recommended 
• Set Image Optimization to 
Seamless Switching (see below). 
• For best results, use the same frame rate and gamma setting for each. 
  
NOTE: Avoid using two Interlaced sources. 
Image Optimization 
Use this setting to choose what is more important, image quality or switching 
between sources. Selecting Best Image Quality will ensure your image is always 
proper however when switching sources, the screen will go blank increasing your 
switching time. Smooth Switching allows for a cleaner transition between sources. 
The image will fade from one image to another according to the Fade Time control. 
Seamless Switching overrides the Frame Lock Enable settings and forces the output

switching sources.  
NOTE: Disable PIP and Best Switching for Interlaced sources > 35kHz. 
Fade Time 
Set how long (in seconds) it takes to gradually dissolve one image into another for a 
source switch. Fading is available for single-image “best” source switching only—
PIP cannot be in use, and Image Optimization must be set to Best Switching. 
NOTE: PIP must be disabled for Fade Time to take effect. Also, the PIP window 
must be closed to activate it. 
Numbers Select Main Image 
Use Numbers Select Main Image to use the 
numeric keys #1-8 as input keys. This remapping 
of the keypad (see right) can be particularly useful 
with PIP displays, providing a convenient shortcut 
for changing the primary (background) image 
without first having to return to the Main menu. To 
use the keys in this manner all of the time, even 
with single displays, select Always. For normal 
keypad function, select Never (default). Set to 
When PIP Active to activate number keys only 
when PIP is in use. 
NOTE: Numbers Select Main Image keypad 
functionality works only when menus are closed. 
 
 
Whenever you install a new lamp in the 
projector, access the Lamp menu to record 
the lamp serial number in the projector’s 
memory. You can also choose a lamp mode 
for regulating power and light output, 
change optical aperture size (if present), 
and access other read-only information 
pertaining to past and present lamps. 
LAMP HOURS (read-only) shows the 
number of hours logged on the current 
lamp. Whenever you record a new lamp 
serial number this value automatically resets to “0”, where it begins to log time for 
the new lamp. This information also appears in the Status menu. 
LAMP S/N (read-only) is the serial number recorded for the current lamp. When you 
install a new lamp and enter its serial number, the number will appear here.

  Roadster/Mirage S+ User’s Manual 3-55 
Enter a checkmark for LAMP MESSAGE to enable a warning message that will appear 
upon power-up when the lamp has reached the specified lamp limit and should be 
replaced. Delete the checkmark to prevent display of this message—instead, when 
your lamp expires, only the status display messages on the back of the projector will 
provide the visual warning to replace the lamp. 
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) 
When a lamp warning message appears, press 
 to temporarily cancel the 
message. The message will continue to appear upon power-up until you install a new 
lamp. 
Set 
LAMP LIMIT to the number of hours you expect to log on the current lamp before 
replacing it. This will trigger a lamp message on-screen (if enabled). 
NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally 
expected may no longer be possible. 2) Turning the lamp on and off repeatedly 
reduces lamp life significantly, as do other factors, such as hot re-striking. 3) It is 
recommended that Lamp Limit not exceed the warranted lamp life, otherwise a lamp 
could become dangerously fragile with overuse. 
Set which 
LAMP MODE you want to use in order to control 
the light output (see Figure 3.26). You can choose to run the 
lamp as bright as possible (i.e., always using maximum 
power—this is the default). Alternatively, power the lamp 
with a specific wattage appropriate for the installed lamp, or 
set a desired intensity (brightness) to maintain. Although there are exceptions, 
generally higher light output or higher power settings can shorten lamp life. 
Use the lamp mode that best suits your brightness needs. For example, in a tiled 
application you may want to precisely match brightness levels between adjacent 
images—judge by eye and set each individual 
Lamp Power setting as necessary. Or 
you may always want images to be as bright as possible—choose 
Max Brightness. 
Keep in mind that higher lamp power settings can shorten lamp life. 
Lamp modes are described below: 
• 
Max Brightness: The lamp will always burn as brightly as possible, driven by 
100% of the power level rating for the installed lamp (see Section 6, 
Specifications). Keep in mind that the “maximum brightness” for any lamp 
gradually diminishes with age—images will become dimmer over time. Its 
current output level appears in the “
Intensity” option (not in lumens). 
• 
Intensity: Brightness will remain close to a specified level for as long as 
possible. Once you select this option, enter a number representing the intensity 
level (brightness) you wish to maintain—the projector will automatically 
adjust power as needed to maintain this intensity as closely as possible. Note 
that the intensity value is a correlation only and does not represent an actual 
lumens level. See “
Intensity” below.  
• 
Power: The power supplied to the lamp will remain at your specified wattage 
level. Once you select this option, enter the number of watts representing the 
power level you wish to maintain. See “
Power” below. 
 
Figure 3.26.

POWER - This slidebar and number indicates how 
many watts are applied to the lamp. You can apply 
anywhere from approximately 60% to 100% of the lamp power rating. Set for the 
number of watts as desired, keeping in mind that lower power levels produce dimmer 
images. When in either 
Power or Max Brightness modes, the power level remains 
constant. Specifying a maximum power level here is the same as operating in 
Max 
Brightness
 mode. 
NOTE: Power level can be set only if the lamp is in P
ower mode. 
INTENSITY – This value and slidebar represents the current brightness of your lamp, 
decreasing over time when you are operating in 
Max Brightness mode or at a specific 
Power level. When you are operating in “Intensity” mode, this value remains at the 
original “
Intensity” setting chosen and cannot be adjusted. 
NOTE: The number shown for “intensity” is not the actual lumen output, but rather 
a correlated value only—1246 may represent 3500 lumens, for example. 
To use “
Intensity” mode, judge by eye or meter and 
set the level as desired for your application. Over 
time, the projector will automatically increase the 
power supplied to the lamp as needed to maintain the chosen intensity as closely as 
possible. This mode is known as “Brightness Tracking” or “LiteLOC™”. 
HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your Intensity 
setting until the required power reaches the maximum rating for the lamp. The lower 
the setting, the longer it will take to reach this threshold, and the longer you can 
maintain the desired brightness. Keep in mind that once the lamp power reaches its 
maximum wattage (see “
Power”, above), this tracking is no longer possible. At this 
point, the lamp will gradually begin to dim as usual, even though your original 
“
Intensity” value will still appear in the menu. To resume accurate tracking, reduce 
the intensity setting so that the resulting “
Power” value is less than its maximum—the 
lower the intensity, the longer it can be maintained. 
For example, a 1000-watt lamp can be driven at no more than 1000 watts. To produce 
desired brightness at the screen, a new lamp would likely need less than this 
maximum rating—perhaps 812 watts (example only). Over time, however, the lamp 
will require more and more current in order to generate the desired light, until 
eventually the lamp wattage reaches its 1000-watt maximum and the lamp power 
automatically levels off. At this point, the tracking function terminates (i.e., the 
power level stabilizes) and the lamp will begin to dim normally. Either reduce your 
“
Intensity” setting or replace the lamp. 
Do not lower the “
Intensity” so much that the corresponding Power value reaches its 
minimum—the intensity setting will be inaccurate and cannot be maintained. For best 
results in achieving uniform intensity amongst tiled images, choose an 
Intensity 
setting that enables all lamps to operate at less than the maximum number of watts 
available in your projector but high enough to keep the corresponding lamp power 
above its minimum. See “
Power”, above. 
NOTES: 1) Lamps become more stable over time, thus a specific intensity is more 
easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in 
“Intensity” mode 3) Intensity cannot exceed the output of Max Brightness mode.

LAMP HISTORY -
 This read-only option lists the lamps most 
recently installed and recorded in the projector. Lamp History 
automatically updates whenever you record a new lamp serial 
number—the new lamp is added to the bottom of the list. 
Use 
CHANGE LAMP to record the serial number for a newly 
installed lamp: 
In the Lamp S/N window, use the number text entry keys to record the new lamp 
serial number and press 
 again to accept the change (see Figure 3.27). See Using 
Slidebars and Other Controls if you need help entering the number. Once entered, 
the new lamp serial number will be added to the Lamp History menu and the Lamp 
Hours timer will reset to “0”. Lamp Mode and Lamp Limit remain as they were for 
the previous lamp and can be changed at any time. 
 
Figure 3.27. Recording the New Lamp Serial Number 
NOTE: Enter a serial number only if you have just installed a new lamp. This will 
help ensure that lamp timer is not reset on an old lamp and that the number of hours 
logged on the lamp will be accurate.
 
 
 IMPORTANT  
ALWAYS record the serial number of a NEW lamp. 
When a new lamp is installed and its 
serial number recorded by selecting 
“Change Lamp” in the Lamp menu, the 
lamp timer resets to “0” and begins 
logging time for the new lamp. This 
tally appears in both the Lamp menu 
(see right) and the Status menu. 
To review the number of hours logged 
for previous lamps, consult the Lamp 
History menu. 
If the “Lamp Message” checkbox has 
been enabled in the Lamp menu (recommended), an expiry message will appear upon 
power-up when the lamp has reached its defined “Lamp Limit”.

In addition, the LED’s next to the built-in keypad will flash “LP” when lamp time 
has expired. The lamp should be replaced. 
The “Lamp Limit” setting should not exceed the warrantied lamp lifetime, as an old 
lamp becomes increasingly fragile and more prone to sudden failure.  
See also 4.4, Replacing the Lamp & Filter and Section 6, Specifications. 
The read-only Status menu lists a variety of details about the standard and optional 
components currently detected in the projector. Refer to the Status menu for versions 
of hardware and software installed, the type (size) of lamp defined in projector 
memory, and hours logged in total and for a specific period (such as a rental period), 
and for your projector model name and serial number. In addition, the Status menu 
identifies the current channel, its location, its frequencies and other details. 
Scroll the full Status menu using 
 . Use  for page up/down. 
When an installation requires multiple projectors, you can use the RS232 serial ports 
to daisy-chain the units together and control the group with a single keypad or a 
computer/controller connected to the first projector. In such a network, you can 
choose to broadcast commands to the entire group, or use the 
Pr o j key as desired to 
limit responses to an individual projector. 
Alternatively, you may want to add projectors to a hub on an Ethernet network. See 
2.6, Connecting Multiple Projectors for full routing details. 
NOTE: Refer back to 3.7, Adjusting System Parameters and Advanced Controls for 
complete information about communicating with multiple projectors. 
In a multiple-projector wall, you will likely want to precisely match color and intensity 
from image-to-image so that the full wall is as uniform as possible. This matching is 
typically done in conjunction with brightness uniformity and edge blending. 
Preliminary Calibration 
As a final part of the manufacturing process, all primary colors in the projector are 
precisely set to pre-established values to ensure that overall color performance is 
optimized and is as accurate as possible (refer back to Figure 3.23). Upon installation 
at a site, however, lighting and other environmental factors may slightly change how 
these colors appear on your screen. While the change is negligible in most cases, you 
may prefer to recover the originally intended color performance before trying to 
match colors from several projectors. Or you may be renting a projector in which the 
colors were corrected for use at its previous site, but are not ideal for yours. 
The recommended first step in achieving such consistency is to use a color meter to 
measure the native primary colors—red, green, blue, and white—as they appear at 
the screen and record these as Color Primary Settings in the Service menu (password-
protected) for each projector. On the basis of these new values, which are stored in 
memory, each projector will then automatically calculate any necessary corrections to 
reproduce the original factory colors under the current environmental conditions. 
This essentially calibrates a projector to its surroundings, compensating for factors 
such as screen type; lamp and/or ambient lighting that can alter the final color 
characteristics on-screen, and will improve color accuracy and consistency in a group 
of projectors. It ensures a good starting point for further customizing and matching; 
however, is not critical for all installations.

To return to the factory-set color primaries, such as when a projector is moved to 
different site, you must access the Service menu (password-protected). Select the 
Reset to Factory Defaults? option in the Color Primaries submenu. Then repeat the 
calibration process describe above, if desired, and continue with matching of colors. 
Color Adjustment Procedure 
Once the Color Primary Settings are calibrated for the site (see above), use the Color 
Adjustments by X,Y or Color Saturation menu to further refine each projector’s 
fundamental colors so that the hue and intensity of each color appears the same from 
one display to another. Once matched, you will have created a single new shared 
range of colors or “color gamut” that all of your projectors can produce. This 
palette—named User 1, 2, 3 or 4—can be applied or disabled for a source at any time 
throughout a bank of adjacent displays, simplifying both the setup and maintenance 
of a “seamless” wall. 
1.  Set up and optimize all projector settings. You can ignore color temperature, since 
you will be redefining color performance in this procedure, but do optimize each 
projector in every other aspect. Closely align all screen edges. 
2.  Assign projector numbers to make communications easier. Use desired keypad. 
3.  Use the same lamp mode for all projectors, and do the following:

values to 100 and the 
secondary values to 0. 
Then judge by eye and 
adjust the slidebars as 
needed. Note that 
adjustments here define

WHAT IS BRIGHTNESS UNIFORMITY? When used to refine screens already matched 
for their primary colors (see Matching Colors in Multiple Screens, above) and overall 
light output, proper adjustment of Brightness Uniformity can create an exceptionally 
smooth screen in which: 
• no area of the screen appears more red, green or blue than another  
• no area of the screen appears brighter than another 
• color and light output from one screen closely matches adjacent screens 
Although the Brightness Uniformity control can be used for a stand-alone projector, it 
is particularly useful for setting up and maintaining tiled images that form a cohesive 
display wall in which the color “cast” and light output appear uniform throughout 
each image as well as throughout the entire wall. The procedure provided here 
assumes a multiple-screen application. 
 Before You Begin 
Read through the entire procedure before attempting to adjust Brightness Uniformity 
controls, and keep in mind the following checklist of prerequisites and guidelines:
