Positioning the Projector 67
To determine the projection distance when you know the diagonal size
of the screen image:
❐ Inches:
Maximum projection distance = (3.5094 × diagonal size) - 6.6568
Minimum projection distance = (2.1090 × diagonal size) - 6.8519
❐ Centimeters:
Maximum projection distance = (8.9139 × diagonal size) - 16.9083
Minimum projection distance = (5.3569 × diagonal size) - 17.4038
Fixed Wide Angle Lens Calculations
If you are using the optional fixed wide angle lens, use the following
formulas instead.
To determine the minimum and maximum diagonal
size of an image when you know the projection distance:
❐ Inches:
Maximum diagonal size = (0.730 × projection distance) + 3.919
Minimum diagonal size = (0.616 × projection distance) + 3.050
❐ Centimeters:
Maximum diagonal size = (1.8542 × projection distance) + 9.9542
Minimum diagonal size = (1.5646 × projection distance) + 7.7470
To determine the projection distance when you know the diagonal size
of the screen image:
❐ Inches:
Maximum projection distance = (1.619 × diagonal size) - 4.702
Minimum projection distance = (1.367 × diagonal size) - 5.640
❐ Centimeters:
Maximum projection distance = (4.1122 × diagonal size) - 11.9430
Minimum projection distance = (3.4721 × diagonal size) - 14.3256
