3. Adjust the Focus using the focus knob 
to retract the lens. ( Figure 4-2) Watch 
the image at the left edge of the screen 
until it comes into fo cus. If the entire 
screen is in focus, proceed to step 7. 
4. Continue retracting the lens.   a. If the right side of the image comes into focus before the le ns is completely 
retracted, adjust the horizontal boresight 
bolt to balance the le ft and right edges. 
 b. If the right side of the image fails to come  into focus, adjust the horizontal boresight 
bolt. 
5. When both sides appear equally blurry, adjust  the horizontal or vertical offset to re-center the 
image.
6. Repeat steps 1 - 5 until both sides of the image  are focused.
7. Tighten the horizontal hold screw to maintain your  adjustments. 
8. Check the boresight again.

4.7 Adjust Top and Bottom Boresight
1. Focus the image at the top edge of the screen.
2. Loosen the vertical hold screw. 
3. Extend the lens focus completely. 
4. Adjust the Focus knob to retract the lens. Watch 
the image at the top edge of the screen until it 
comes into focus. If the en tire screen is in focus, 
proceed to step 8.
5. Continue retracting the lens.   a. If the bottom edge of the image  comes into focus before the lens 
is completely retracted,  adjust the vertical boresight bolt to direct 
or aim the lens mount UP towards the top of the screen to bal-
ance out the top/bottom edges. 
 b. If the top edge of the image is  not in focus, adjust the vertical 
boresight bolt to direct or aim  the lens mount toward the bottom 
of the screen. 
6. When both sides appear equally bl urry, adjust the horizontal and/or 
vertical offset  to re-center the im age on the screen.
7. Repeat Steps 2 - 5 until the top  and bottom of the screen are both 
well-focused.
8. Re-focus the center of the image.  The goal is for good focus at the 
center and on all sides.
9. Tighten the vertical hold screw  to maintain your adjustments.
10. Check the boresight again.

4.8 Adjust Top and Bottom Boresight with an ILS
1. Loosen the Vertical Locking Screw.
2. Extend the lens focus completely. 
3. Adjust the Focus to retract the  lens using the counter-clockwise 
button on the ILS Adjust window. Wa tch the image at the top edge 
of the screen until it comes into  focus. If the image appears well-
focused on the top edge but no t on the bottom, we need to 
determine if the bottom edge focuses in front of or behind the 
screen. If the entire screen comes  into focus, skip to step 8.
4. Continue retracting the lens.   a. If the bottom edge of the imag e comes into focus before the 
lens is completely retracted, th en the image focuses in front of 
the screen. To correct this problem, adjust the  Ve r t i c a l  B o r e -
sight  Bolt  to direct or aim the lens  mount UP towards the top 
of the screen to balance  out the top/bottom edges. 
 b. If the top edge of the imag e fails to come into focus 
then the image focuses behind the screen. To correct 
this problem, adjust the  Vertical Boresight Bolt  to 
direct or aim the lens mo unt DOWN towards the bot-
tom of the screen. 
5. When both sides appear equally blurry, tap  Menu > 
Advanced Setup  > ILS File Setup  and tap the 
directional arrows in the  Offset area to center the image 
on the screen.
6. Repeat Steps 2 - 5 until the  top and bottom of the screen 
are both well-focused.
7. Although all sides of the im age should now be in focus, 
the center of the image may be slightly blurry at this  point. Re-focus the center of the image. The goal is 
for good focus at the  center and on all sides.
8. Adjust the  Vertical Locking Screw  to lock the lens mount in place and check boresight again.
4.9 Adjust DMD Convergence
 UV EXPOSURE! Protective UV glasse s must be worn when performing 
convergence adjustments.
A convergence problem occurs when one or more projecte d colors (red, green, blue) appears misaligned when 
examined with a convergence test pa ttern. Normally, the three colors should overlap precisely to form pure 
white lines throughout the image and one or more poorly  converged individual colors may appear adjacent to 
some or all of the lines. Contact your Christie acc redited service technician to correct DMD convergence 
issues.

4.10  Fold Mirror Adjustment
If a corner or edge of an image is missing, the fold mirror might be misaligned with the optical system. To 
correct this issue:
•  Adjust the screw closest to the oper ator’s side (right side, when facing screen) to raise or lower the image.
•  Adjust the screw on the left side  to move the image left or right.

4.11 Calibrate the System 
Use the TPC to calibrate the image color performance and define electronic screen masking. This is required in 
your particular installation for the creation of S ource, Screen, MCGD and TCGD files necessary for proper 
display of incoming material. You can also define th e system/network configuration for communication links 
to the cinema projector and transmit information to and from the CP2230 via an Ethernet or RS-232 
connection. 
4.12  Color Calibration
To ensure an accurate color display:
1. Measure the colors displayed on the screen from the  center of the audience viewing location to determine 
the Measured Color Gamut Data (MCGD) value. 
2. On the Touch Pad Controller tap  Menu > Advanced Setup > MCGD File Setup  and enter the color 
values in the x and y fields for the different colors. 
3. Tap  Save. The software automatically de termines the Target Color Gamut Data (TCGD) value. The TCGD 
value determines what corrections are ne eded to display the correct colors.
4.13 Electronic Screen Masking
You can use the masking tool to correct image edge bl anking. The masking tool produces results that are 
similar to filing the aperture plate in  a film cinema projector. After you create the Flat and Scope screen files 
you can use them in multiple channels.
4.14 Work with 3D
This section provides informatio n and procedures for setting up and managing 3D presentations.
4.14.1 Display Requirements
To display 3D images with the CP2230 ci nema projector, you require these items:
• Two HD-SDI cinema signals (left and right) connect ed to the cinema projector’s SMPTE ports HD-SDI A 
and HD-SDI B.
• A 3D hardware system: • Pi-Cell polarizer for display on a screen that has a s ilver polarization-preserving surface for use with pas-
sive glasses (RealD).
• Rotating polarizing wheel (external) with passive  circular polarizing glasses (MasterImage). Requires a 
silver screen.
• IR emitter for controlling the left eye/right eye gating (switching) of active glasses (Xpand).
• Dual cinema projector 3D - passive glasses (circular or linear). Requires a silver screen.
• A 3D connection cable: • 3D sync output cable (GPIO) .
• 3D connector.
• Power supply for your sync output device.
