The BrightLink Pro 1410Wi/1420Wi/1430Wi, BrightLink 475W/485W/575Wi/575Wi+/585Wi/585Wi+/595Wi/
595Wi+/675Wi+/685Wi/685Wi+/695Wi/695Wi+, and PowerLite 475W/485W/575W/585W/675W/685W can
project a WXGA image up to 100 inches diagonally. The BrightLink Pro 1450Ui/1460Ui and BrightLink 696Ui/
697Ui can project a WUXGA image up to 100 inches diagonally. The BrightLink 480i and PowerLite 470/480/
570/580/680 can project an XGA image up to 93 inches diagonally.
This guide covers your projector's native resolution and aspect ratio. For other
resolutions and aspect ratios, use the Throw Distance Calculator at
www.epson.com/support (U.S.), www.epson.ca/support (Canada), or
www.epson.com/jm/support (Latin America).
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.
When installing the Touch Unit (if applicable) on a whiteboard, you need at least 4.7 inches (120 mm) between
the top edge of the projected image and the top edge of the projection surface. If you want to install the
Touch Unit outside of the frame of a whiteboard, use the included Touch Unit Bracket. If the distance from the
wall to the surface of the whiteboard is greater than 2 inches (51 mm) or the frame of the whiteboard extends
more than 0.1 inch (3 mm) away from the board surface, you must install the Touch Unit on the whiteboard or
screen.
See the documentation included with your projector for details on mounting the
Touch Unit.
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 on page 14. If you are projecting on a plain
wall, use the worksheet on page 15.
When installing the Touch Unit on a whiteboard (if applicable), make sure to leave the
following gaps around the edge of the board:
❏
From the top of the projected image to the bottom of the Touch Unit: 1 to 4 inches
(25 to 100 mm)
❏
From the edges of the projected image to the edges of the board: at least 4 inches
(100 mm) left and right
❏
From the bottom of the projected image to the bottom of the board: 0.8 inch
(20 mm)
If there are obstacles such as cables, whiteboard trays, pen holders, or frames within
the areas listed above, the Touch Unit will not operate properly.
