Positioning The Projector; Installation Worksheet For Projecting On A Pre-Installed Wall-Mounted Board - Epson BrightLink 475Wi Installation Manual

4 Positioning the Projector

BrightLink 475Wi/485Wi and PowerLite 475W/485W can project up to 100 inches diagonally for a WXGA
image or 88 inches diagonally for an XGA image. BrightLink 480i and PowerLite 470/480 can project up to 93
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 wall mount) 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.
