Installation Worksheet for Projecting on a Plain Wall

Use this worksheet to determine where to position the wall mount for a BrightLink
projecting on a plain wall.
(1) Measure the ceiling height (distance from the floor to the ceiling).
(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
(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)
(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.
(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).
(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.
