Screen/AspectRatio
Both 4:3 and 16:9 screens are fully supported with proper aspect ratio control for both type sources using NEC developed
scaling technology. Menu selections have settings for each screen type and aspect ratio control for each source type.
Notes
•For screen sizes not indicated on 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 any local
building codes.
•Distances are in inches, for millimeters multiply by 25.4.
•Distances may vary ±5%.
Formulas
The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size
varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to
calculate all screen dimensions. Plug in the image width for “W” in the Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2 and 3.
Projection Formulas: Definitions:
GT06RLB: C=0.6178W–2.287 W=Image Width
GT10RLB: C=1.0034W–2.087 H=Image Height (Size)
GT12ZLB: C(Wide)=1.2029W–2.823 --- C(Tele)=1.7223W–2.788 C=Throw Distance
GT19ZLB: C(Wide)=1.7010W–3.385 --- C(Tele)=2.2392W–3.272
GT20ZL: C(Wide)=2.0021W–3.987 --- C(Tele)=2.6237W–3.949 4:3 Screen Formulas:
GT24ZLB: C(Wide)=2.2181W–4.895 --- C(Tele)=3.2670W–4.836 W=Hx4/3
GT34ZLB: C(Wide)=3.2445W–7.016 --- C(Tele)=4.9132W–6.863 H=Wx3/4
GT48ZLB: C(Wide)=4.9390W–13.829 --- C(Tele)=7.2886W–13.586 Diagonal=Wx5/4
16:9 Screen Formulas:
W=Hx16/9
Note:Tilting the front of the projector up or down by more H=Wx9/16
than 45° from level could reduce lamp life by up to 20%. Diagonal=Wx18.358/16
