Basic Image Alignment

NOTICE! Assumes projector is fully assembled and powered up in its final location.
This procedure ensures that the image reflected from the DMDs is parallel to and well-centered with the lens
and screen. This initial optical alignment is the foundation for optimizing images on the screen and must be
completed before final boresight adjustments. Ensure the CP2210 is properly positioned relative to the screen
before you begin. Refer to

2.7.1 Basic Optical Alignment Procedure

1. Display a good test pattern appropriate for analyzing image focus and geometry, such as the "framing" test
pattern showing the crosshair centered across the image.
2. Course focus: Perform a quick preliminary focus and (if available) zoom adjustment with the primary lens
only. Focus the center of the image first, consistency across the image is not required at this point.
3. Center the image in the lens: Holding a piece of paper at the lens surface, adjust the offsets as necessary
until the image is centered within the lens perimeter. A full white field works best for this.
4. Re-check side-to-side leveling: With the framing test pattern on screen, re-check projector leveling (refer
to 2.3.2 Step 2: Adjust Tilt/Leveling, on page
the screen.

Offset and Boresight Alignment

NOTES: 1) Projector must be fully assembled and
powered up in its final location. Install the auxiliary lens,
if it will be used at the site. 2) A 5mm hex key is needed to
make the required adjustments.
To ensure proper offset for your site and consistently
good focus in all areas of the screen, a primary lens must
be installed and its lens mount precisely adjusted in
relation to internal optics, as described below. In some
applications a wide converter lens (WCL) or anamorphic
lens can be used to accommodate changes between flat
and "scope" cinema displays.

2.8.1 Adjust Offset

IMPORTANT! Ensure the correct lens is selected
in the Advanced Setup: Lens Setup window
before calibration to ensure you will remain within the applicable boundary of the installed
lens when adjusting.
Project an image with the primary lens only. Always adjust offset before boresight. Using the framing test
pattern, adjust horizontal and vertical Offset as necessary to display a square image on the screen with minimal
projector aiming error. NOTES: 1) For best optical performance, make sure to minimize keystone error by
using offset more than aiming to center the image in off axis installations. 2) Avoid extreme tilts or offsets.
Corner vignettes on a white test pattern indicates extreme offset that should be avoided using mechanical
alignment.
