Epson PowerLite 720 User Manual page 15

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
Projection distance
3.0 to 6.6 feet
4.1 to 8.8 feet
6.2 to 13.3 feet
8.3 to 17.7 feet
10.4 to 22.2 feet
12.5 to 26.6 feet
15.7 to 33.3 feet
21.0 to 44.5 feet
31.5 to 66.8 feet
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
epson.com/support.
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.
