2 | KNOWLEDGE BASE – ADJUSTING THE IMAGE WITH THE UF55/UF55W
PROJECTOR
The image appears shorter across the top when the image path’s distance from the
projector to the top of the screen is shorter than the distance to the bottom of the
screen. The image appears shorter across the bottom when the image path’s distance
from the projector to the bottom of the screen is shorter than the distance to the top of
the screen. Vertical keystone errors can occur when you mount the UF55/UF55w
projector and the SMART Board 600 series interactive whiteboard on an uneven
surface or a wall that has obstructions.
Horizontal keystone errors can occur when you swivel the UF55/UF55w projector too
far from the SMART Board 600 series interactive whiteboard’s vertical center, when
you mount the projector and the interactive whiteboard on an uneven surface, or when
the board is slightly closer to the projector on one side than the other.
The image appears shorter across the right side when the distance from the projector
to the right of the screen is shorter than the distance to the left of the screen. The
image appears shorter across the left side of the image when the distance from the
projector to the left of the screen is shorter than the distance to the right of the screen.
Adjust the interactive whiteboard side to side to center the image (from the projector),
as illustrated in the installation guide. This eliminates many keystone errors. If your
installation environment prevents you from moving the interactive whiteboard, you can
adjust the projector boom for optimum image alignment.
NOTES
• If you move the interactive whiteboard system to a new location, you must
realign it.
• If your projector requires service, you must adjust the replacement projector.
