The maximum vertical

offset is shown in

Figure 2.35, (bottom

illustration).

NOTES: 1) Horizontal

offset is just a few

dozen pixels, resulting

in a maximum of 52%

of the image displayed

on one side or the

other of the lens. 2)

Maximum offsets are

slightly less when

offsetting in both

directions (H an V) at

once.

NOTE: Use a test pattern with

a single pixel vertical and

horizontal line and perimeter

frame.

1. Adjust focus at the far left

center edge of the image

(Figure 2.36). 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:

 On small accessible screens, 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.
