Alignment
NOTE: By default
from the
manufacturer, this
projector is optimized
for brightness rather
than wider color
gamut or higher
contrast ratio—i.e.,
neither a small-
diameter contrast
ratio aperture nor the
yellow notch filter is
installed in the
projector. These are
options.
Upon powering up the
projector with a
newly-
installed/replaced
lamp, adjust lamp
position to help ensure
optimized operation as well as peak brightness at the screen—you do not need an
image displayed yet. Once you have done this LampLOC
be well-centered and distanced correctly from the remainder of the illumination
system. It can be re-adjusted as needed at any time.
For best results in most applications, use the "Do Auto" button. The motorized lamp
adjustments will begin and, in conjunction with an internal light sensor, will take a
minute or two to position the lamp for optimized brightness. If desired, you can
operate the motors individually and use the "Intensity" reading at the top of the menu
for feedback.
NOTE: Lamp must be on and shutter open during LampLOC
the projector does not need to be displaying an image.
NOTE: Assumes a single projector is powered up in its final location.
This initial optical alignment procedure is the foundation for optimizing your
displays, ensuring that images reflected from the DMDs are parallel to and well-
centered with both the lens and screen. It should be completed before adjusting lens
boresight.
NOTE: Before you begin:
Properly position the projector relative to the screen (refer back to 2.3, Projector
Position & Mounting).
Basic Optical Alignment Procedure
1. Display a good test pattern appropriate for analyzing image focus and geometry,
such as a single crosshair centered across the image.
