Notes
• For screen sizes not indicated on the projection charts, use the formulas below.
• If a value in a chart does not match the results of the formulas, use the values in the chart.
• The ceiling must be strong enough to support the projector and the installation must be in accordance with any local
building codes.
• All formulas are based on a 4:3 aspect ratio and screen.
• Distances are in inches, for millimeters multiply by 25.4.
• Distances may vary ±5%.
Formulas (for a 4:3 screen)
Units: Inches (for millimeters multiply final number by 25.4)
Definitions:
Projection Formulas:
W = Screen Width (4:3)
(discontinued) GT10RL: C = 1.027W – 2.468 H = Screen Height (4:3)
GT10RLB: C = 1.0891W – 2.087 C = Throw Distance
GT13ZL/13ZLB: C(Wide) = 1.3099W – 2.325 --- C(Tele) = 1.6111W – 2.325
(check availability)GT19ZL/19ZLB: C(Wide) = 1.8639W – 3.228 --- C(Tele) = 2.4231W – 3.228 Screen Formulas:
GT20ZL: C(Wide) = 2.1731W – 3.987 --- C(Tele) = 2.8477W – 3.949 W = Screen Diagonal x 4/5
GT24ZL/24ZLB: C(Wide) = 2.4282W – 4.799 --- C(Tele) = 3.5209W – 4.799 H = Screen Diagonal x 3/5
GT34ZL/34ZLB: C(Wide) = 3.5523W – 6.786 --- C(Tele) = 5.3284W – 6.786 Screen Diagonal = W x 5/4
