Adjust Left/Right
Boresight
1. Adjust focus at the
far left center edge
of the image
(Figure 2.45). If
possible, reduce
image size for
easier image
analysis.
2. If the image
appears well-
focused on the left
edge but not on the
right, then the
boresight currently differs from one side to the other—i.e., the right side of the
image is well-focused either in front of or behind the screen surface rather than on
it. To determine where the right side is focusing:
Hold a piece of white paper approximately parallel to the screen surface at the
right side (and as close to the vertical center as possible), then move closer to
the projector while watching the image on the paper.
• If focus on the paper
improves, this
indicates that the
right side of the
image is focusing in
front of the screen.
See Figure 2.46.
• If focus on the paper
worsens, this
indicates that the
right side of the
image is focusing
behind the screen.
GOAL: If the image comes
into focus on both sides
simultaneously, left/right
boresight is fine—skip to Step 7.
