Screen/Aspect Ratio
4:3, 16:9 and 16:10 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 tables, use the formulas below.
If the figures on the tables do not match the results of formulas, use the figures in the table..
Distances are in inches, for millimeters multiply by 25.4.
Distances may vary 5%.
Formulas: 16:10 Aspect Ratio (PX750U—WUXGA)
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: 16:10 Screen Formulas
NP16FL: C = 0.794W – 1.85 W = Image Width W = H x 16/10
NP17ZL: C(Wide) = 1.281W – 2.094 ------ C(Tele) = 1.825W – 1.913 H = Image Height (size) H = W x 10/16
NP18ZL: C(Wide) = 1.764W – 2.677 ------ C(Tele) = 2.313W – 2.638 C = Throw distance Screen Diagonal = W x 18.868/16
NP19ZL: C(Wide) = 2.261W – 3.150 ------ C(Tele) = 3.747W – 3.114 16:9ScreenFormulas
NP20ZL: C(Wide) = 3.654W – 5.319 ------ C(Tele) = 5.492W – 5.299 W = H x 16/9
NP21ZL: C(Wide) = 5.469W – 11.626 ------ C(Tele) = 8.527W – 11.531 H = W x 9/16
Screen Diagonal = W x 18.358/16

Application
The diagram below shows the location of the image
position in the lens. The lens can be shifted within
the shaded area as shown using the normal
projection position as a starting point.
Note: Lens shift feature is not available with
NP16FL (rear lens). NP16FL should be used only
for “zero degree” / “no-offset” applications.
Note: Projector is set out of the box at maximum
lens shift, which is how it is depicted above.

Data Length: 8 bits
Parity: No Parity
Stop Bit: One bit
X on/off: None
Communications: Full duplex
PC Control Connector (D-Sub 9P)
Note 1 : Pins 1, 4, 6, and 9 are used inside the projector.
Note 2: For long cable runs it is recommended to set communication speed within the projector to 9600 bps.
Note 3: Jumper “Request to Send” and “Clear to Send” together on both ends of the cable to simplify cable connection.
