Use the Tiling Setup submenu to define the size of a wall (number of rows and
columns), and identify the location of each projector in the wall. If you are
operating a stand-alone unit, enter “1” for items 1 to 4.
Figure 3.35.
For the image on a display wall to appear seamless, color and brightness must be
precisely matched from screen to screen. This requires the adjustment of the
projector’s primary colors from the Adjust Primary Colors menu.
NOTE: Projectors manufactured later than August 2005 are color-adjusted at
the factory to reduce adjustment time at site. Thus projectors should closely
color-match following installation. Only minor adjustment should be required.
Use the procedure below to ensure you achieve a uniform display.
When matching screens in a display wall, do the following:
NOTES: 1) It is recommended that you begin this procedure with all projectors
at the same power level - 100W recommended setting. 2) Look at the center of the
screen when performing this procedure. 3) A color meter can be used, but is not
required to successfully perform this procedure. 4) Color matches are optimized
for graphic sources. If using video sources with over-adjusted primary colors,
you may notice a slight posterized or banded effect in images. 5) It is
recommended that you look at the white color temperature again after installing
a new lamp.
Step 1: Preliminary Setup
1a) Setup and optimize all projector settings – Optimize projector settings
without trying to match color temperature or perceived light output at this
point. E.g. Adjust size, position, and geometry.
1b) Assign projector ID numbers – Make sure each projector is assigned a
unique 2-digit number. This allows you to switch between communicating to
one projector or all projectors.
1c) Display a 16-step grey scale test pattern with black on the left and white on
the right with 16 equal sized levels and run the Auto Input Level option.
NOTE: Test patterns are provided on the CD found in the User’s Kit.
