Product Description

Type: 1 chip DMDTM Lens-less projector Dimensions: 15.0”(W) x 12.3”(H) x 12.3”(D) w/final mirror up
4 mirror bounce optical system Weight: 14.1 lbs
Native Resolution: 1024 x 768 (1024x768 for 16:9 screens Screen Range: 40” – 100” Diagonal (4:3)
Brightness: 2000 lumens (1500 ANSI)

Screen/Aspect Ratio_

Both 4:3 and 16:9 screens are fully supported with proper aspect ratio control for bo th 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.
 The ceiling must be strong enough to support the projector and the instal lation 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 the screen width in for “W” in the Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 2 and 3.

Definitions:
W = Screen width W = H x 4/3
H = Screen height H = W x 3/4
B = Vertical distance between projector foot and screen center Screen Diagonal = W x 5/4
C = Throw distance
D = Vertical distance between projector foot and screen bottom

(screen top for ceiling mounted application) 16:9 Screen Formulas:
W = H x 16/9
H = W x 9/16

Projection Formulas:
B = 0.6882W + 3.935
C = 0.4874W - 13.056
D(4:3) = 0.3132W + 3.935
D(16:9) = 0.407W + 3.935

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 DLP 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. (See “Screen Type” and “Position” in user manual)

4:3 Screen Formulas:

Screen Diagonal = W x 18.358/16
