The most suitable distance between the screen and the projector (see Projection distance [a]) depends on the size of the screen (diagonal
length) you use. You can use the zoom function to adjust the projection distance within a preset range from Wide to Tele. You can also alter
the V.POS parameter to adjust the vertical position of the image to better suit the screen. Use the information in the table below to determine
the best location to place the projector in to suit your screen size.
Projection distance

Since the DPX-1100 has a 16:9 panel, the ideal installation location for use with a 4:3 screen depends on the size of the image you wish to
view.

* These are theoretical values.
During actual use there may be a deviance of a few percent.
(*1) Projects a 16:9 image that completely fills the screen (leaves a black line at the top and bottom of the screen).
(*2) Projects a 4:3 image that completely fills the screen.
(*3) When projecting both 16:9 and 4:3 images.
You can use the zoom function to make efficient use of the screen for both *1 and *2 above. The projection distance in this case is
between Wide in *2 and Tele in *1. Use the zoom to adjust the size of the projection images so that they fill the screen completely. Note
that adjustments to V.POS may cause the position of the image to change.

Follow the instructions to adjust the position of the projected image on screen.

This illustration shows the limits within which the
zoom function can alter projection distance [a] in
relation to screen size. You can adjust the image
within these limits so that it fills the screen
completely. (  page 21)

You can adjust the vertical position of the
projection image up or down by half of the height
of the screen. For example, shifting V.POS fully up
brings the lower limit of the image above the
centerline of the lens. ( page 20)

If you mount this unit on a tabletop, you can use the adjusters on its underside to change the
position of the projection image. Rotate the movable part of the two screw-type adjusters at
the front bottom of the case to adjust the height. The movement range of the adjusters is 3cm
(1-1/4 inch). Adjust with care as loosening them further than 3cm may cause them to
separate from the unit.
Projection image position

Keystone adjustment
If you mount the unit at an angle to the screen, it projects trapezoidally distorted images. You can use the [keystone Correction] item in the
[Setup] menu group to rectify this. ( page 22-34)
Memo
•If the keystone is adjusted aspect ratio may not be correctly maintained. To correctly maintain the aspect ratio, try to use the DPX-
1100 with the lens shift in the center position.
•The video may be disturbed by keystone correction. Wherever possible, we recommend setting up so the screen and projector
form a right angle.Wide Tele

Glossary
The following is a list of key words used in the use of projectors and image signals and their explanations. Please refer to it when using this
manual.
For an explanation of vocabulary used in the menu, refer to Menu group items and functions” (  page 25).
11Reference
Ceiling mount bracket
The mounting hardware used to hang this unit from the ceiling.
Two types of bracket are available, for high and low ceilings.
Ceiling mount brackets are sold separately.
Cinemascope size
The widest film format in 70mm film, with an aspect of 2.35:1.
Color spacing
The conversion of YUV color separated signal to RGB signal.
There are two formats for this, BT.601 for SDTV, and BT.709 for
HDTV. This unit switches between them as required.
Component video signal
A method of sending video signals with independent luminance
and color signals. Component video gives a higher image quality
than ordinary composite video because it bypasses mixing and
separating circuits. Component video signal consists of three lines,
the luminance signal (Y), and two color difference signals (P
B/CB,
P
R/CR).
Composite video signal
The most common type of video signal, combining luminance and
color signals in one line. This method requires mixing and
separating processes on both the send and receive sides. Use a pin
cable for connection.
DCDiTM function
Directional Correlational Deinterlacing, a high quality image
circuitry developed by the Faroudja company. DCDi uses edge
cutting techniques to remove jagged edges from images during
Interlace to Progressive conversion, allowing smooth, natural
reproduction of images.
DLPTM technology
Digital Light Processing, an image display engine used in
projectors that use the DMD™ chip developed by Texas
Instruments.
D terminal
A cable that allows transmission of all of the signals in composite
video in one cable. This method is used for transmitting image
signals between the latest AV components. There are 5 methods of
transmission, D1-D5. This unit is compatible with D4.
HDCP
A technique designed to protect the video transmission between a
DVI or HDMI transmitter and a display device.
HDMITM
High-Definition Multimedia Interface, a method of differentially
transmitting digital RGB/component video signal from computers
and home digital equipment.
HDTV
High-Definition Television, a term used to define systems that
satisfy the following conditions:
•A vertical resolution of 720p or 1080i (p stands for progressive
scans, ; stands for interlace scans)
•A 16:9 aspect ratio
Interlace
The most common type of scanning used in televisions. It divides a
screen into even and odd numbered fields for scanning, and then
builds an image by combining them into one image (frame).
Keystone Correction
Using the unit at an angle to the screen distorts the projected image
trapezoidally. You can use Keystone Correction to electronically
correct this distortion.
Letterbox
A method of converting the content of landscape oriented film to a
4:3 signal. You can watch landscape images without trimming them
by adding a black bar to the top and bottom of the screen, however
this sacrifices vertical resolution to some extent.
Progressive
A method of displaying all scanning lines in a frame at once,
reducing flicker noticeable on a larger screen and creating a sharp,
smooth image. This unit uses progressive scanning for progression.
RGB Signal
A method of transmitting color information using a numeric
representation of the primary colors red, green, and blue separately.
When received, it is expressed in various colors by adding a mixing
colors. RGB is widely used for sending and receiving color images
between computers, and requires horizontal and vertical sync
signals.
SDTV
Standard Definition Television, a term used to define normal
television broadcasts which do not meet HDTV standards.
Smart zoom
Expands the left and right sides of a 4:3 image without altering the
center, when you are attempting to project a 4:3 image on a wide
screen format. This creates some distortion at both edges.
Squeeze
A method of compressing film images horizontally to an aspect of
ratio of 4:3 when recording to video medium. The raw image is
oblong, so needs to be passed through a desqueezing circuit to be
projected in it’s original form.
Standby
The state in which the circuit that receives infrared-signals from the
remote control is active, but all other main circuits are turned on.
The unit consumes a small amount of power in this state.
S Video  signal
S stands for Separate. A method of sending signals with separate
luminance (Y) and color (C) signals. Use a 4-pin mini DIN
connector and cable for connection.
Sync.
Computers output signals with a given regular frequency, which
you must synchronize the projector to in order to produce a good
quality image. If you do not match the phase of the signal, the
image may be flickery, faded, or distorted.

							52
Test pattern
This unit contains test patterns which you can use to adjust the
position and focus of the projected image on the screen.
Tracking
Computers output signals with a given regular frequency, which
you must synchronize the projector to in order to produce a good
quality image. If you do not match the phase of the signal, vertical
stripes may appear on the image.
Vista size
A standard film size, with an aspect ratio of 1.85:1 in North
America, and 1.66:1 in Europe.
3-2 pulldown detection style IP conversion
A function for directly converting interlace signal into sixty frame
progressive signal used when receiving 60 field interlace signal
from an image source recorded with the same 24 frames as movie
film. This allows DVD and other materiel recorded with 24 frames
to be projected on large screens as a natural, precise image with no
loss of quality, comparable to a movie film.
