Notes

• For screen sizes not indicated in the projection charts, use the formulas below.

• The ceiling must be strong enough to support the projector and the installation must be in accordance with an y local

building codes.

• Distances are in inches, for millimeters multiply by 25.4.

• Distances may vary ±5%.

Formulas

The Projection Formulas us e the image width for calculation. For proper projector placement, determine the image width for a

desired screen size. Use the Screen Formulas below to calculate all screen dimensio ns. Plug in the image width for “W” in the

Projection Formulas.

Refer to the diagrams and charts for popular screen sizes on page 2.

Definitions: 16:9 Scre en Formulas:

W = Image Width W = H x 16/9

H = Image Height (Size) H = W x 9/16

B = Vertical distance bet ween lens center and screen center Screen Diagonal = W x 18.35756/16

C = Throw distance

Projection Formulas:

B(min) = 0.1877W

B(max) = 0.4710W

C(wide) = 1.6695W – 1.913

C(tele) = 1.9801W – 1.883

α(wide) = tan-1 (B/C(wide))

α(tele) = tan-1 (B/C(tele))

Note: Factory preset is B(max)/maximum lens shift.
