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 consistent image quality–whether good or
poor–across the screen, proper aspect ratio and enables optimization of pixel phase
(below).
NOTE: By default, the projector will sample at the correct frequency for most sources.
Make sure that pixel tracking is set to 1424 or higher for 3D images.
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.
3L[HO 3KDVH

6+257 &87 Press 3L[HO 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.
)LOWHU
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.

“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.
%ULJKWQHVV

6+257 &87 Press %UL JKW 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.
&RORU

6+257 &87 Press &RORU and adjust the slidebar.)
“Color” adjusts color saturation level, or the amount of color in a video image. For
example, setting Color to 0 produces a black and white image. If Color is set too
high, the color levels in the picture will be over-powering and unrealistic. Use 
or  until the desired color saturation level is displayed.
7LQW

6+257 &87 Press 7LQ W and adjust the slidebar.)
“Tint” adjusts color hue to obtain true color reproduction of NTSC video signals or
HDTV signals. Use 
 or  until the you reach optimum balance of red-to-green
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.
HWDLO

6+257 &87 Press  and adjust the slidebar.)
“Detail” adjusts the sharpness of the video image. Use 
 or  until the display
is as sharp as possible, keeping in mind that any level of detail above 3 (default) will
increase the level of detail as well as introduce some level 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.

“Color Temp” applies either a preset color temperature (3200K, 5400K, 6500K,
9300K) or any previously defined Interpolated or custom “User” color temperature.
All 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” can
be defined in the 
Advanced Color Temperature menu or the
Adjust Primary Colors (CSC) menu. Until defined, these
choices all default to 6500K. See 
Section 3.7, Adjusting System
Parameters and Advanced Controls.

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 
,1387  or ,1387 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 
,1387  or ,1387 , the color
space function is entirely automatic and the pull-down list disabled.

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.
()$8/7 GHIDXOW ²  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. “Default” is the only Gamma setting available when using
the Adjust Primary Colors feature—see 3.9, Using Multiple Projectors
 for details.
(1+$1&( ²This 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.
+,*+ $0%,(17 ² This setting elevates low gray levels compared to the “Default” and
“Enhanced” settings. In high ambient light conditions, details can be seen in the dark
parts of an image that would otherwise be difficult to perceive.
3$/6(&$0 ²This setting results in a darker image with higher contrast. The gamma
curve more closely matches the official standard for PAL and SECAM video signals.
/,1($5 ²This 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.
Use the Communications, Preferences and Status menus to display and/or alter
overall system parameters rather than those that affect a specific source or channel.
Use the Advanced menu whenever you need to work with or replace the lamp, select
a test pattern, define a new color temperature, or access lesser-used image control
settings intended for experienced users.
Use the checkboxes and pull-down lists in the Communications menu to alter the
methods or types of communication to and from the projector. Refer to Using

The baud rate setting determines the speed of communications to and from the
projector. By default, the projector baud rate is set to 19200. Setting the correct speed
is important when you are controlling the projector with an external
device such as a computer or another projector via an RS-232 or RS-
422 port. You must set the projector baud rate at these ports to match
the baud rate of the controlling device. If you are unsure about what
baud rate to choose, refer to the documentation for the controlling
device. In an existing network, if you discover that a projector has the
wrong baud rate, make sure to use the pull-down list and select the
correct baud rate with the 
(QWHU key—do not just scroll this control with
 and  keys.
NOTE: 
1) The baud rate setting does not affect the switcher port, which is always
9600 baud. 
2) See 
2.9, Serial Port Connections and 
Appendix D for more
information about cable connections between devices.

As described in Section 2, the standard IR remote keypad is capable of
sending data to the projector in either one of two protocols called 
$
 or
%. Likewise, the front and rear IR sensors on the projector can be set to
accept IR data accordingly, responding to 
$ %or both. The projector’s
$RU% default is adequate for most single-projector installations. Select
a specific protocol to prevent interference when you are controlling
two protectors in the same area and want to work with one projector at a time.
Note that the front and rear IR sensors cannot respond to different protocols–if you
change a protocol for either sensor to anything other than 
2)), the protocol for the
other sensor also changes. For example, setting Front IR to 
% also changes the Back
IR to 
%. If you want only one sensor to respond to a particular protocol—$, %, or $RU
%
—disable the other sensor by setting its protocol to 2)).
If you want to disable both IR sensors, you cannot use the IR remote keypad to select
the second 
2)) setting. This safeguard prevents accidentally disabling a keypad
while you are using it. Instead, use either the built-in keypad or the wired remote to
set the remaining active sensor to

projector from responding to the keypad entirely. In the pull-down list, select the
desired protocol.
NOTE: The wired keypad for this projector is set at manufacture to Protocol A. See
2.10, Keypad Protocols and Conversion for information about changing the keypad
protocol.

opposite protocol or select 
2)) using the wired keypad. Instead, if you want to
quickly change to the other protocol, you may find it more convenient to use one of
the other keypads (the built-in keypad or the IR remote) to execute the protocol
change for the wired keypad. The projector will now recognize only the opposing
wired keypad protocol. Or, if you prefer, use the wired keypad to safely change its
own protocol:
1.
 Select the 
$RU% option. This will ensure that once your keypad is
manually changed (see Step 2), it will still be recognized by the
projector.
2.
 Unplug the keypad and change the protocol in the keypad as desired. Do
this either by entering the short-cut software command or by hard-wiring
the keypad as described in 2.10, Keypad Protocols and Conversion.
3.
 Plug the keypad back into the projector. Return to the Communications
menu and select the new protocol you have just set up in the wired
keypad.

Enter a three-digit number (such as 001) to assign or change a number to the
projector currently in use–if the current projector already has a number assigned, that
number will appear here. Numerical
identity for projectors is required whenever
you want to communicate with a single
projector within a multiple-projector
application (see 
 key description in
3.3, Using the Keypad). If you make a
mistake in assigning or changing the
projector number, press

NOTES: 
1) Requires double serial links—RS-232 and RS-422—between all
projectors in a network. 
2) Set each projector’s Broadcast Key OFF. 
3) Keypads
cannot broadcast in a split network—use controller(s) instead. 
4) Do not use a split
network when downloading new projector software to a network.
Enter a Split Network checkmark if you have a network in which each projector is
connected via both its RS-232 and RS-422 serial ports (Figure 3.18A). At each
projector, serial communications will then remain on either its RS-232 or RS-422
path (depending on the controller) rather than being broadcast to all 3 remaining
serial ports. Should a projector or path ever fail, the other path will be available as a
back-up. The Split Network feature is unnecessary when only a single serial link is
connected between any two projectors (Figure 3.18B), and will cause communication
errors if these single links vary from RS-232 to RS-422 anywhere in the network.
Likewise, if you have two serial links connected between any two projectors, failure
to use the Split Network checkbox can also cause a communication error.
