4. Positioning the Projector
The BrightLink 455Wi can project up to 96 inches diagonally for a WXGA image or 85 inches diagonally for an
XGA image. You can project onto a pre-installed whiteboard or directly onto a plain wall. The height of the
included wall mount determines the maximum image size and how high the image appears on the wall or
whiteboard. The distance of the projector from the wall (once it is mounted on the adjustable arm of the
setting plate) also affects image size and position.
If you are planning to project on a whiteboard, the image may not fill the entire board, depending on the
aspect ratio. If you match the image height to the board’s height, gaps may appear on the sides of the board.
Use the following worksheets to determine the proper location of the wall plate on the wall. If you are
projecting onto a pre-installed whiteboard, use the worksheet below. If you are projecting on a plain wall, use
the worksheet on page 10.
