notice a slight posterized or banded effect in images. 6) It is recommended that you
look at your primary colors again after installing a new lamp or if there is a change
in the lamp operation mode (this occurs automatically if a lamp fails during
operation).
Step 1: Preliminary Setup
1a) Set up and optimize all projector settings – It’s not important to set up
color temperature at this point. It is however, important to try and get all other
projector settings as close to perfection as possible. Also make sure the edges of
adjacent screens are close to one another.
1b) Assign projector ID numbers – Make sure each projector is assigned a
unique 3-digit number. This will give you the freedom to switch between
communicating to one projector (
Proj
###) or all projectors (
Proj Proj
).
1c) Display a 100% internal white field test pattern on each screen.
It is strongly recommended that you select the internal 100% white field test
pattern when adjusting primary colors. Important: If you choose to use an
externally generated 100% white field test pattern, set Contrast and Brightness
to 50 for each projector and turn the White Boost off (set to a value of 0). Then,
in the Input Levels menu, set input levels correctly for each projector while
displaying an external 256-step grayscale.
1. Enter a checkmark for the Auto Input Level option.
2. Wait for the 6 values (blacklevels and drives) to stabilize.
3. Delete the checkmark and leave the Input Levels menu. Input levels are
now correct for the source. Switch to the external white field for the
remainder of this procedure.
NOTE: Avoid using a digital source (particularly YUV) for the white field.
1d) Set all projectors to the same lamp power and lamp operation mode.
It is recommended that you begin with a lamp power of 100W for each projector
and set all projectors to the same lamp operation mode you intend to operate
them in before you continue with adjustments. NOTE: You can change the lamp
power setting later. Do not try to match perceived light output at this point.
STEP 2: Establish Starting Point for Color Adjustment
2a) ENABLE PRIMARY COLOR ADJUSTMENT. In the Adjust Primary Colors (CSC)
menu, enter a checkmark in the Use Primary Color Enable checkbox so that
primary color controls can be adjusted and applied to the image.
If at any time you decide not to use or apply the Adjust Primary Colors (CSC)
feature, delete the checkmark – this disables Red, Green and Blue Primary
controls (and they will appear grayed out in the menu).
