Positioning The Projector - Epson PowerLite 420 Installation Manual

4 Positioning the Projector

BrightLink 425Wi/435Wi/436Wi and PowerLite 425W/435W can project up to 113 inches diagonally for a
WXGA image or 100 inches diagonally for an XGA image. BrightLink 421i/430i and PowerLite 420/430 can
project up to 106 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 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.
Refer to the tables on the following pages and install the mount and projector to project images at the
appropriate size. The values are only a guide. The recommended projection distance is 27.6 to 46.9 inches
(70 to 119 cm).
