Making Fine Adjustments to the Projected Image
When you've properly positioned the projector or the mirror stand, you can make fine adjustments
to obtain a correctly projected image on the interactive whiteboard. An aligned image fits squarely
on the interactive screen with a margin of about 1/2" (1.3 cm) on all sides.
1/2" (1.3 cm)
This section of the guide provides general guidelines for adjusting the projected image from any
projector (see below). However, if you have a 2876 or a 2976, this section also includes detailed
instructions on adjusting the projected image from an NEC VT676 projector (page 25).
NOTE: A keystone image occurs when the edges of your image are not parallel. Your projector
may have a feature for automatically correcting this issue. However, don't use this feature. If the
edges of your projected image are not parallel, correct it using the methods detailed on the
following pages.
To align and adjust the projected image
1. If the left and right edges of your projected image are not parallel, raise or lower the projector
at the front or back until the edges are parallel.
2. If the top and bottom edges are not parallel, turn the projector slowly until the edges are
parallel.
3. Adjust the projected image using small, slow movements until you're satisfied with the image.
–
Correct the image size by moving the projector forwards or backwards until the image
correctly fills the interactive screen.
–
Correct the image's horizontal and vertical position by adjusting the height and position of
the projector platform or stand.
–
Create a clear image by adjusting the projector's focus function.
NOTE: The method for changing the projected image depends on your projector. For more
information, see the instructions supplied with your projector.
