9xx Series Projection Distances For Standard Screen Sizes
In the tables below, you will find the projection distance ranges to fill standard screen sizes for each of the four available lenses on
9xx Series projectors. The screen sizes are listed in the left column. The diagonal measurement is listed first, and the screen height and width is listed in parentheses.
The second column shows how far away from the screen you need to place the projector to fill the corresponding screen.
Try not to place the projector at its maximum or minimum zoom setting. Also, when possible, place the projector as close to the screen as feasible. The closer the projector is to the screen, the brighter the resulting image. The projection distances below are approximate, due to lens manufacturing variances.
When determining where to mount a
9xx Series projector and where to place the screen, you can also control the vertical location of the image by changing the
lens shift. The lens shift feature allows you to move an image up and down without
causing keystone distortion.

Calculating image sizes
Here is how to calculate the range of image sizes from a specific throw distance for
9xx Series projectors.
Note
—The following procedures use SAE measurements. The calculations for metric measurements are the same.
To calculate the diagonal image size
You can use the diagonal image size calculation for screens with a standard 4:3 aspect ratio. For 16:9 HDTV screens, use the horizontal calculation below.
-
Multiply the distance between the screen and the projector times the maximum zoom lens setting.
-
Multiply the distance by the minimum zoom lens setting.
This gives you the range of diagonal image sizes possible from one location.
For example, if the projector with the standard zoom lens is placed 10 feet away from the screen, multiply 10 x .5 to get 5 feet (60"). Then multiply 7 x .69 to get 6.9 feet (about 83"). Thus, at 10 feet, the range of diagonal image sizes possible is 60 to
83 inches.
Note
If you're calculating image sizes for the optional ultra wide lens, you need only one calculation.
To calculate the horizontal image size
You can use the horizontal screen size calculation for screens with the standard 4:3 aspect ratio and those with 16:9 aspect ratio.
-
Divide the distance between the screen and projector by the maximum zoom lens settings.*
-
Divide the distance by the minimum zoom lens setting.*
* Use the settings below for each lens.

Using the above example, if an
9xx Series projector is 10 feet (120 inches) from the screen and the zoom lens is set to the maximum image size, the resulting image is about 67 inches across. At the minimum zoom setting, the image is about 48 inches in width.
Top
9xx Series projectors include a
lens shift
feature that allows the user to do the following:
-
Adjust the vertical image position on the screen without raising or lowering the projector.
-
Adjust the height of the projector without raising or lowering the screen.
The lens shift adjustment is particularly useful when mounting a
9xx Series projector in a rear projection system.
Using the lens shift avoids any keystone distortion. Turn the lens shift knob on the side of the projector to make this adjustment. The lens shift has a 0º to 12º range.
When the lens shift is set
to the
maximum
(+ 12º), the bottom of the image is even with the center of the projection lens. See the illustration below.
When the lens shift is set to the
minimum
(0º), the center of the image is even with the center of the projection lens. At this point, half of the image is above the centerline and half is below.
The
lens shift feature can also be used with ceiling mounted projectors. This allows the projector to be mounted within a range of heights to project an image on screen. Likewise, the location of the screen can be adjusted without moving the projector.
