/$03 61  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 in the Lamp
 menu.
NOTE: Read-only.
Enter a checkmark for 
/$03 0(66$*(  if you want to enable a warning message
upon power-up that the lamp has reached the specified lamp limit and should be
replaced. Delete the checkmark if you do not want to see this warning—instead,
when your lamp expires, only the status information on the back of the projector will
provide the 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 continued to appear upon power-up until you install a
new lamp.
Set 
/$03 /,0,7 to the number of hours you expect to log on the current lamp before
replacing it. The recommended limit is 1000 hours.
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 can reduce lamp
life significantly, as will other factors.
Set which 
/$03 02( you want to use in order to control the
light output. Although there are exceptions, in most lamps, the
higher the light output or power setting, the shorter the life
span of the lamp.
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—choose 
,QWHQVLW\ for each projector, then judge by eye and
set each individual intensity setting as necessary (see “Intensity”, below). Or you
may simply always need as much brightness as possible—choose 
0D[ %ULJKWQHVV.
Lamp modes are described below:
x 
0D[ %ULJKWQHVV The lamp will always burn as brightly as possible, driven by
maximum power of either 500W (Mirage 2000
) or 1200W (Mirage 5000
).
Keep in mind that the “maximum brightness” for any lamp gradually
diminishes with age—images will become dimmer over time. Its current
output level (note: not
 in lumens) appears in the “
,QWHQVLW\” option.
x 
,QWHQVLW\ 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
 (0-9999), not actual lumens level.
See “
,QWHQVLW\” below.
x 
3RZHU The power supplied to the lamp will remain at a desired watt level
throughout the life of the lamp. Once you select this option, enter the number
of watts representing the power level you wish to maintain. See “
3RZHU”
below.

32:(5  The number shown here indicates how many watts are applied to the lamp.
Set from 350-500 watts (Mirage 2000
) or 800-1200W (Mirage 5000
) as desired.
Keep in mind that lower power levels produce dimmer images. When in “
3RZHU” or
0D[ %ULJKWQHVV modes, the power level remains constant. When in “,QWHQVLW\” mode,
the power level will change as necessary. Specifying the maximum power level in
3RZHU mode is the same as operating in 0D[ %ULJKWQHVV mode.
NOTES: 
1) Power level can be set only if the lamp is in “power” mode. 
2) If you are
in “Intensity” mode, the power level value will automatically increase over time as
necessary to closely maintain the desired brightness, until power reaches its
maximum.
,17(16,7< ² This number is a representation of the current brightness of your lamp,
decreasing over time when you are operating at 
0D[ %ULJKWQHVV or at a specific 3RZHU
level. However, when you are operating in “,QWHQVLW\” mode, this value remains at the
original “
,QWHQVLW\” setting chosen.
NOTE: The number shown for “intensity” is not the actual lumen output, but rather a
correlated value only—9999 may represent up to 5000 lumens, for example.
To use “
,QWHQVLW\” mode, judge by eye and set the level as desired for your
application, remembering that higher settings can significantly shorten lamp life.
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 is called
“brightness tracking”.
Keep in mind that once the lamp power has reached its maximum (see “
3RZHU”,
above), such tracking is no longer possible. At this point, the lamp will gradually
begin to dim as usual, even though your original “
,QWHQVLW\” value will still appear in
the menu. To resume accurate tracking, reduce the intensity setting so that the
resulting “
3RZHU” value is under its maximum—the lower the intensity, the longer it
can be maintained.
Do not set “
,QWHQVLW\” so low that the corresponding “3RZHU” value reaches its
minimum (350 watts in Mirage 2000, 800 watts in Mirage 5000)—the intensity
setting cannot be maintained and will be inaccurate. For best results in achieving
fairly uniform intensity amongst tiled images, choose an “
,QWHQVLW\” 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 “
3RZHU”, 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.

This feature, sometimes called color space conversion, enables precise matching of
colors and intensity in multi-screen environments so that a wall of images is as
consistent as possible. Selecting this option activates the Adjust Primary Colors
(CSC) menu, where for each projector you can adjust and judge by eye the specific
hue or “cast” of its individual primary colors—red, blue and green—so that resulting
full color images will be closely matched from screen-to-screen. Primary color
adjustments affect all sources and can be applied or disabled at anytime by entering
or deleting a checkmark at the top of the Adjust Primary Colors  (CSC) menu,
offering a quick and flexible method of color control.
For complete instructions on using the Adjust Primary Colors (CSC) menu, refer to
3.9, Using Multiple Projectors.
NOTE: It is not necessary to adjust primary colors in stand-alone projectors.

Brightness Uniformity provides further refinement of screens already matched for
their primary colors (see Adjust Primary Colors, above) and overall light output,
creating an exceptionally smooth screen in which no area of the screen appears
brighter and/or more red, green or blue than another. Selecting this option activates
the Brightness Uniformity menu, where you can enable the “Uniformity Enable”
checkbox and access a multitude of adjustments for critical color light output control
in specific areas throughout the image. Brightness Uniformity settings are applied as
long as the “Uniformity Enable” checkbox is enabled and you are using the User 1
color temperature defined by the controls. To disable the Brightness Uniformity
function, delete the “Uniformity Enable” checkmark.

Although the Brightness Uniformity control can be used for a single image, it is
particularly useful for setting up and maintaining tiled images as a “seamless” display
wall in which the color cast and light output appear uniform throughout each image
as well as throughout the entire wall.
For best results, avoid “experimenting” with Brightness Uniformity controls—follow
the Achieving Brightness Uniformity procedure provided in 3.9, Using Multiple
Projectors.

A single projector can display 3D images as described below. Such images require a
specialized source as well as additional hardware and software in order to be
displayed and interpreted correctly in a typical 3D active stereo viewing
environment.
In simple terms, images generated from a 3D-video source consist of a series of
images (frames or fields) that alternate quickly between two slightly different 6WDWXV

viewpoints corresponding to the separation of our left and right eyes. When these
frames are displayed with enough speed and viewed with special glasses
synchronized with the left/right frames, the resulting “single” perceived image
appears with much the same depth and perspective we sense in the real world.
Once you have the necessary source and hardware/software setups described below,
you must select the correct Processing Mode option “Minimum Delay” located in the
Advanced Image Settings menu. The projector does not detect and process a 3D
signal automatically. For complete processing information, see 3.7, Adjusting System
Parameters and Advanced Controls.
Note that the “Minimum Delay” setting is applied only to the current source and must
be selected for each 3D source you have connected.
In addition, a Stereo3D
TM system requires the correct Stereo3DTM checkbox setting in
the Advanced Image Settings menu. See 3.7, Adjusting System Parameters and
Advanced Controls.
A 3D-video signal is sent to the projector via analog cables such as:
x 3-wire RGB sync-on-green
x 4-wire RGB with composite sync
x 5-wire RGB with separate H-sync and V-sync
NOTE: Refer to 
2.4, Source Connections for full details and illustrations.
Most 3D signal formats currently available are optimized for display via CRT
(cathode ray tube) technology, thus they have high pixel rates unsuitable for this
projector. By reducing the blanking in these signals, however, you can lower their
pixel rate enough to be compatible with the projector (under 160 MHz). Typically, a
high-end graphics workstation that includes hardware and software tools for
customizing video output timing parameters can produce the requisite 3D signals, as
can a PC running Windows
TM 98/2000 (use the “PowerStrip” utility)—consequently
your 3D displays must originate from either of these sources. The Silicon Graphics
ONYX
TM workstation is an example—it includes Video Format Compiler software
capable of properly modifying “timing” in the signal for use in the projector (it
provides a .vfo file). Other similar workstations may also provide the special video
driver needed.
NOTE: Not all systems include the hardware/software necessary for reconfiguring
the 3D video output timing parameters—these sources cannot be used with the
projector.
In addition, this projector requires the following conditions for 3D work at these
higher frame rates:

x Use a progressive RGB source with native resolution of 1280 x 1024 (can be

a single frame delay, disables resizing and the “Freeze Image” option, and
limits vertical and horizontal position ranges.

must be customized to precisely match the processing capabilities of the
projector. In addition, the source must provide a separate synchronization
signal that precisely controls when left/right fields are visible through the
viewer’s glasses.
x 
,19(57(5: In this projector, 3D processing introduces a single frame delay.
Without correction (i.e., reversal), image data intended for one eye would be
delayed and seen by the other—images would lose their 3D quality entirely. If
a 3D source cannot invert the signal, thereby synchronizing the left/right
shutters in your 3D glasses to match the images displayed by the projector,
you must invert via a left/right TTL inverter or use the Stereo3D
TM Interface
Module and Stereo3DTM checkbox in the Advanced Image Settings menu.
Either configuration ensures that shutter changes in the glasses allow each eye
to receive the image data intended for it, regaining the 3D effect of the display.
NOTE: Depending on your workstation, it may be possible to implement the
reversal of left/right frames through software only, eliminating the need for
separate inverter hardware.

x ,5 (0,77(5: In response to an incoming sync signal, this small device emits
left/right IR signals to a receiver in active 3D glasses, causing their left/right
shutters to alternately open and close for active 3D application. Connecting an
emitter to the emitter port on the Stereo3D
TM Interface Module also enables
you to switch back-and-forth between active and passive systems, if desired.
x 
*/$66(6: Active glasses differ in speed/performance—consult the
documentation for your glasses and keep their specifications in mind when
reconfiguring your source signal. The input signal must be optimized for the
available shutter speed in order to prevent obvious “ghosting” of image
content (known as cross-talk in 3D applications) as well as other more subtle
color artifacts. Such problems indicate that the eyes are detecting portions of
the opposing frame due to an “out-of-sync” system, and can occur in either
active or passive 3D configurations. See Customizing the Input Signal, below,
for examples of well-synchronized systems.
NOTE: In a passive system, where glasses do not have shutters and instead
depend on the speed and accuracy of the Pi Cell polarizer, the input signal
must be synchronized with the polarizer.

0,5$*( 352-(&725
To customize your 3D input signal for use with the projector, you will need access to
software that controls video output timing from the graphics source. For example, the
Video Format Compiler (vfc) and ir combine are required when using the Silicon
Graphics ONYX
TM workstation.
The display must be synchronized with shutter control—called gating—so that each
eye receives only the frames of data intended for it, otherwise you will detect
opposing data frames (cross-talk) and see faulty images. This requirement means that
timing parameters in your source should guarantee the following:
1)
 Each new frame begins after the opposing shutter mechanism is closed
2)
 Each frame completes its display before the opposing shutter mechanism
begins to open.
3)
 Each frame (mirror sequence) is displayed in its entirety to the correct eye.
:KDW 7R $GMXVW
Since current 3D-video sources do not have the necessary characteristics for use with
this projector, you must synchronize the projector’s display with your gating
mechanism by adjusting the vertical sync width and/or vertical back porch of the
input signal and, in many cases, by adjusting the projector’s Dark Interval control.
These two parameters—input timing and dark interval—are described below. Note
that because they interact with each other, you may have to go back and forth
between them when optimizing the 3D display. In general, vertical frequency + Dark
Interval/10 = 110 Hz or less.
1)
 Vertical sync width and/or 
vertical back porch blanking of your input source.
Choose the vertical sync width and/or vertical back porch timing to determine
when the next field begins displaying relative to the vertical sync signal. The
degree of timing adjustment needed depends on the specific signal at hand as
well as the performance of your glasses. An example of improvements to poor
synchronization is shown in Figure 3.34. After adjustment, shutter changes
occur during the dark interval between frames. 6RIWZDUH 5H

  “Dark Interval” projector control (note: not always required). For slower
gating technologies, you may also need to artificially increase the amount of
dark time between displayed frames so that shutters have even more time to
open/close and each eye sees the full display intended for it (Figure 3.35B).
Symptoms are more subtle than cross-talk—if the dark interval is too brief for
proper gating, you may notice an apparent color temperature problem, with
some whites or grays appearing with a slight red, green or blue tint. This color
artifact is particularly easy to diagnose in a grayscale test pattern displayed in
3D mode (i.e., with Minimum Delay). In the Advanced Image Settings menu,
increase the “Dark Interval” as necessary until the grayscale is correct—you
may also have to increase the internal delay when using a longer Dark
Interval. Note that the Dark Interval default is approximately 375 µs, but
slidebar values range from 0-255 and do 
not indicate µs.
