Positioning The Projector - Epson BrightLink 450Wi Installation Manual

4. Positioning the Projector

The BrightLink 450Wi and PowerLite 450W can project up to 96 inches diagonally for a WXGA image or 85
inches diagonally for an XGA image. The PowerLite 460 can project up to 102 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.
