(2) Determine the desired aspect ratio of the image. For new computers or laptops,
this will most likely be WXGA (16:10). For older equipment, this will most likely be
XGA (4:3). You may need to consult your IT director for this information.
___ 4:3 XGA ___ 16:10 WXGA ___ 16:9 Widescreen
(3) Using the tables in the Installation Guide for your aspect ratio, select the largest
image size available for your ceiling height.
Image height (h)
Image width (w)
_____ (h)
_____ (w)
(4) Determine the desired distance from the floor to the bottom of the image area
(f).
The recommended minimum distance is 30 inches. Images appearing less than
28 inches from the floor may be obstructed for some viewers.
_____ (f)
(5) Find the top of the projected image area by adding distances (f) and (h). _____
(6) Use the tables in the Installation Guide to determine the required distance from
the top of the image area to the bottom of the wall plate (c). _____ (c)
(7) Add:
Required distance from top of image area to wall plate (c)
Height of image area (h)
Distance from floor to bottom of image area (f)
Height of wall plate plus cover
If the total exceeds the ceiling height, you will need to reduce the image size or
reduce the distance from the floor to the bottom of the image area.

from the top of the image area on the board to the bottom of the wall plate.
(9) Align the line (horizontal) on the template sheet with the (c) mark, then align
the center line on the template sheet with the center of the image area. Follow
the instructions in the Installation Guide to install the projector.

(7) Determine the aspect ratio of the board or of the images that will be projected.
For new computers or laptops, this will most likely be WXGA (16:10). For older
equipment, this will most likely be XGA (4:3). You may need to consult your IT
director for this information.
___ 4:3 XGA ___ 16:10 WXGA ___ 16:9 Widescreen
(8) Using the tables in the Installation Guide for your aspect ratio and desired image
height (h), find the required distance between the top of the image area and the
wall plate (c).
_____ (c)
(9) Determine the position for your projector installation by adding the values for (f),
(h), and (c), plus an additional 10 inches for the height of the wall plate plus the
cover.
If the ceiling height of your room (as noted in step 1) does not meet the
minimum ceiling height required for your board, you may need to select a
smaller image size or move the board to a lower position on the wall.
_____ (f)
_____ (h)
_____ (c)
