Screen/Aspect Ratio
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

Lens Shift Adjustable Range
The top right diagram shows the location of the image position in the lens. The lens can be shifted within the shad ed area as shown
using the normal projection position as a starting point.
Maximum Possible Range for GT12ZLB/GT20ZL/GT48ZLB lenses:
*Values for 16:9 screens in parentheses.
Up: 0.5H (0.67H) H=Height of image (take care to use appropriate value for 4:3 or 16:9 screens)
Down: 0.5H (0.67H) W=Width of image
Right: 0.32W
Left: 0.32W
Note: Lens shift is not available on GT06RLB & GT10RLB rear lenses, which should only be used for “zero degree/no-offset” applications.
Note: If the lens is shifted in two directions combined, maximum range in either direction cannot be obtained due to rounded off area of
lens. (example: shift up and right) See top right diagram.

Warning:
• Installing the projector on the ceiling must be done by a qualified
technician.
• Tilting the front of the projector up or down by more than 45° from
level could reduce lamp life by up to 20%.
• Only use the projector on a solid, level surface. If the projector falls,
you could be injured and the projector severely damaged.
• Do not use the projector where temperatures vary greatly. The
projector must be used at temperatures between 32°F (0°C) and
95°F (35°C).
• Do not expose the projector to moisture, dust or smoke. This will
reduce the quality of the image.
• Ensure that you have adequate ventilation around the pro jector so
heat can dissipate. Do not cover any vents on the projector.
