Notes
•
•
•
For screen sizes not indicated on the projection tables, use the formulas below.
If the figures on the tables do not match the results of formulas, use the figures in the table.
The ceiling must be strong enough to support the LCD projector and the installation must be in accordance with any local
building codes.
All calculations are based on 4:3 aspect ratio.
Distances are in inches, for millimeters multiply by 25.4.
Distances may vary ±5%.
Formulas
Units: Inches (for millimeters multiply final number by 25.4)
Definitions: H = Horizontal Screen Width (4:3)
V = Vertical Screen Height (4:3)
C = Throw Distance
Projection Formulas:
GT10RL: C = 1.027H – 2.468
GT13ZL: C(Wide) = 1.3099H – 2.325
GT19ZL: C(Wide) = 1.8639H – 3.228
GT24ZL: C(Wide) = 2.4282H – 4.799
GT34ZL: C(Wide) = 3.5523H – 6.786

C(Tele) = 5.3284H – 6.786

Application
The diagram below shows the location of the image position
in the lens. The lens can be shifted within the shaded area as
shown using the normal projection position as a starting
point.
Note: Lens shift feature is not available with GT10RL (rear
lens). GT10RL should be used only for “zero degree” / “nooffset” applications.
Note: If lens is shifted in two directions combined, maximum
range in either direction cannot be obtained due to rounded
off area near edge of lens. (example: shift up and right)
