3.1 Setup: An Overview
"Setup" means adjusting displays electronically so they operate properly and look their best. There are
many steps in this process. Some need to be done in order, and some can be done out of order. After
the setup, save your work.
You have installed the displays mechanically,
connected them to power and data signals, and
now it is time to adjust them electronically. The
list of steps shown below is for reference only.
Each step is briefly described here, but the de-
tails of what to do for each step are given in the
sections that follow.
The steps should be performed in this order,
unless a note in the step tells you differently.
1. Select the Source—The display has two
(or, optionally, four) input connectors on
the rear for picture data. Some of the steps
are different for computer sources (inputs
PC1 and PC2, p. 3-10) than for video
sources (optional inputs C-Video and
S-Video, p. 3-16). For each connector that
you use, you should perform all the other
steps in this list.
2. Adjust the Input—For computer sources,
this step tells the electronics module what
voltages to expect from the computer for
black level and for maximum white level.
These levels are always different from one
computer to another (p. 3-20). For video
sources, this step adjusts black and white
levels, but in a different way (p. 3-24).
3. Matching Frequency and Phase—Do this
for computer sources only (p. 3-22). It
matches the electronics module's internal
clock to the external computer signal.
4. Save the Settings—Save the settings as
you work. Each input has a separate mem-
ory, so you can setup for two computers
and save all the settings for them sepa-
3 - 2
rately, one on each connector. It is a good
idea to save the settings several times as
you go through the setup process (p. 3-26).

Note: If you only have one display, you can skip
everything else in this list.
5. Wall Processor—If you use Clarity's Big
Picture™, you can distribute one picture to
all the displays and spread this one picture
over the whole video wall (p. 3-28).
6. Position and Size—You need to position
and size the image to make the edges
match exactly. Clarity's Big Picture does
almost all the work for you, but some mi-
nor adjusting may be necessary (p. 3-32).
7. Matching Colors—In a video wall, it is
important that all the units show the
same brightness and color (p. 3-34). This
prevents an image of a car driving across
the screen from changing color—red on
one side of the wall, but changing to or-
ange when it gets to the other side. (This
step can be performed at any time after
the wall is built. It does not affect other
adjustments, and other adjustments don't
affect it.)
8. Save the Settings again—Always save the
settings (p. 3-26). Whenever you change
something, think, "Do I want to save this
change? Do I want the displays to turn on
this way, or the way it was before?"
The next two subsections, 3.1.1 and 3.1.2, dis-
cuss some general topics related to setup.
