First make certain that only one (any) networked projector has its "Broadcast Keys"
option selected (checked) — the remaining projectors must have the option
unchecked and their keypads disabled (do this in Preferences menu). The "Broadcast
Keys" projector will then relay keypad commands to the others. If using a wired
remote, make sure to select the "Broadcast Keys" option for the projector to which
the wired remote is connected.
On either the IR remote or wired keypad, press
Press
again without entering a number — the keypad commands will now affect
all projectors. Due to time lags in network communications, direct number entry is
recommended when broadcasting a parameter adjustment—i.e., holding
will not ensure uniform adjustment, since more remote projectors are subject to time
delays and will "fall behind". Instead, enter the desired value to broadcast.
NOTE: If you are using a computer or controller to issue commands, use the correct
RS-232 software command to broadcast.
In a multiple-projector wall, you will likely want to precisely match image color and
intensity from screen-to-screen so that the wall is as uniform as possible. The first step in
achieving such consistency is to use the Adjust Primary Colors (CSC) menu to fine-tune
each projector's fundamental primary colors—red, green and blue—so that each color
hue and intensity appears exactly the same from projector to projector. Once matched,
these colors work together to essentially create a single new color temperature or "image
cast" that all projectors can attain (range is 5250-6750K). This setup can be applied or
disabled at any time throughout the wall, simplifying both the setup and maintenance of a
"seamless" wall. Follow the step-by-step instructions below.
NOTES: 1) During this procedure, look at the center of each screen. 2) On-line hints
and help can guide you through the procedure. 3) A color meter is helpful but not
required. 4) Color matches are optimized for graphic sources. If using video sources
with radically adjusted primary colors, you may notice a slight posterized or banded
effect in images.—you may have to forfeit some color matching to eliminate this. 5)
Review primary colors upon installation of a new lamp.

Use of the internal white field is strongly recommended. If, however, you still
prefer to use an externally generated white field, set Contrast and Brightness
to 50 for each projector. Then, in the Input Levels menu, set input levels
