ZOOM:
If you have a zoom lens, rotate the lens barrel
end (closest to the projector) as desired to increase or
decrease the image size.
If you don’t have a zoom lens or if you can’t adjust the
image enough, the projector is likely not positioned at the proper throw
distance for your screen size. Power down, unplug the projector and move it
towards or away from the screen. See 2.3, Projector Position and Mounting
for details.
•
CHECK VERTICAL OFFSET:
To ensure that the image is
located as desired and that the image is a proper
rectangle rather than “keystoned” (having non-parallel
sides), turn the vertical offset knob located on the top of
the unit near the front edge—this is the knob closest to
the lens. Try to achieve the desired overall image position while obtaining a
rectangular image with the best overall brightness. If the image remains
keystoned, the projector may be too high or low for the screen. Also, ensure
that the projector is perpendicular to the screen. See 2.8, Zoom, Focus and
Offset and Figure 2-10.
•
CHECK HORIZONTAL OFFSET:
To mechanically place
your image slightly left or right of center, turn the
horizontal offset knob located on the top of the unit near
the front edge—this is the knob nearest the corner of the
projector. See Figure 2-9.
•
FOCUS:
When the image is the right size and shape,
rotate the lens barrel (at the end furthest from the
projector) until the image is as sharp as possible.

Although DLV 1280 delivers both high resolution and high brightness output,
your final display quality could be compromised if the projector is not properly
installed. This subsection discusses issues you should consider before
proceeding with a final installation. Even if you do not intend to use the
projector in a fixed and permanent installation, this subsection will help you to
better understand what may be done to ensure maximum performance.
