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. By selecting the screen type in the menus, Aspect Ratio control is reconfigured for that screen type.
• For a 4:3 screen; select “4:3” in the “Screen” menu for proper aspect ratio control of 4:3 and 16:9 sources.
• For a 16:9 screen; select “16:9” in the “Screen” menu for proper aspect ratio control of 4:3 and 16:9 sources.
*Factory default “Screen” setting is “4:3”.
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.
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.
Definitions: 4:3 Screen Formulas:
W = Image Width W = H x 4/3
H = Image Height (Size) H = W x 3/4
B = Vertical distance between lens center and screen center Screen Diagonal = W x 5/4
C = Throw distance
α = Projection angle
W = H x 16/9
Projection Formulas: H = W x 9/16
B = 0.375W Screen Diagonal = W x 18.358/16
C (wide) = 2.7264W – 5.276
C (tele) = 4.2864W – 5.354 Vertical Position for a 16:9 screen: The Vertical Position a djustment moves the 16:9
α (wide) = tan
α (tele) = tan
Position is dependent on aspect ratio and 3D Reform used. If 3D Reform is not used,
the approximate range of Vertical Position is +/-0.167H (H=Screen Height) when using
a 16:9 screen.
Note: To avoid premature lamp failure, do not tilt the front of the projector up or down by more than 75° from level. Tilting the front of the
projector up or down from 15° to 75° might reduce lamp life by up to 25%.

Vertical Position for a 16:9 screen
The Vertical Position adjustment moves the 16:9
image up and down in the unused portion of the
4:3 panel. This adjustment is only available when
the projector is set for ‘16:9’ in the ‘Screen’ menu.
The range of Vertical Position is dependent on
aspect ratio and 3D Reform used. If 3D Reform
is not used, the approximate range of Vertical
Position is +/-0.167H (H=Screen Height) when
using a 16:9 screen.
Note: For screen sizes not indicated on the chart,
use the formulas on page 1.
Note: “NA” means it is outside the lens range for
