Setting Up the Projector
15
To determine the exact image size when you know the projection distance (or the exact
projection distance when you know the desired image size), you can use the Image Size
Calculator. This program is available on the Epson website at epson.com/support (U.S.) or
epson.ca/support (Canada).
Also keep these considerations in mind:
■ Make sure there is plenty of space for ventilation around and under the projector. Do not
set the projector on top of loose materials that could block the vents underneath.
■ Make sure the projector is within 9.8 feet (3 m) of a grounded electrical outlet or
extension cord.
In order to view 3D images correctly, 3D glasses must be worn within proper range of the
projector. Use the image below to determine the ideal distance for 3D projection (the shading
represents the 3D viewing area):
24.2 to 51.3 feet
7.36 to 15.62 m 200 in. (161 × 118 in.)
508 cm (410 × 300 cm) 55 in.
139 cm 175 in.
444 cm –100.4 to 100.4 in.
–255 to 255 cm
4:3 aspect ratio (continued)
