The maximum size of the image is determined by the distance from the projector's lens to the screen. Depending on your display settings and how you use the Zoom ring, the actual size may be smaller. Use this table as a rough guide for projector placement: 16:9 aspect ratio 4:3 aspect ratio Projection distance Maximum diagonal Projection image size distance Maximum diagonal image size 2.9 to 4.4 feet 30 in. (26 × 15 in.) 3.5 to 5.3 feet 30 in. (24 × 18 in.) 3.9 to 5.9 feet 40 in. (35 × 20 in.) 4.8 to 7.2 feet 40 in. (32 × 24 in.) 5.9 to 8.9 feet 60 in. (51 × 28 in.) 7.2 to 10.8 feet 60 in.

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 Projection Distance Calculator. You can download this program from the Epson website at http://support.epson.com. 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 of a grounded electrical outlet or extension cord.
