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)

V= Vertical Screen Height (4:3)

C= Throw Distance

Projection Formulas: ScreenFormulas:

GT10RL: C = 1.027H – 2.468 H= Screen Diagonal x 4/5

GT13ZL: C(Wide) = 1.3099H – 2.325 ------- C(Tele) = 1.6111H – 2.325 V= Screen Diagonal x 3/5

GT19ZL: C(Wide) = 1.8639H – 3.228 ------- C(Tele) = 2.4231H – 3.228 Screen Diagonal = H x 5/4

GT24ZL: C(Wide) = 2.4282H – 4.799 ------- C(Tele) = 3.5209H – 4.799

GT34ZL: C(Wide) = 3.5523H – 6.786 ------- C(Tele) = 5.3284H – 6.786
