Ultra bright 4,000-lm
The PT-D4000E offers 4,000 lumens of
brightness, thanks to the newly developed AC
lamp and more efficient reflectors and synthetic
mirror. Real-life images are also produced in
rooms with the lights turned on.
System daylight view
The system daylight view function uses an
image processing circuit to compensate
for the loss of colour saturation that
occurs when light reflects onto the screen
from bright surroundings. It is especially
effective for producing crisp, sharp
images in dark portions containing
gradation. The function can be adjusted in
three steps.
Full 10-bit picture
processing
The use of a full 10-bit image processing system
provides smooth tonal expression. For example,
skin tones appear natural and true to life.
New IP
conversion circuit
The PT-D4000E features a new IP conversion
circuit that produces more detailed images than
our previous models.
More effective
noise reduction
Images are noticeably clearer, thanks to higherperformance
frame noise reduction, which lowers
image graininess, and improved MPEG noise reduction,
which suppresses the block noise and mosquito noise
that are common in fast-action scenes.
Progressive cinema
scan (3/2 Pulldown)
This interlace/progressive conversion technology
automatically detects when the input signal is
derived from filmed material and selects the
optimum progressive processing method to
assure faithful reproduction of the original image.
3D colour
management system
Compensation provides optimal levels of colour
saturation, hue, and brightness that were not
possible with conventional projectors. Colours
approach those of the original image, even on
large-screen displays.
Dynamic
sharpness control
The dynamic sharpness control circuit adjusts
the video signal waveforms based on the
difference in brightness of adjacent pixels for a
sharp, clear picture that is relatively unaffected
by signal noise.
Excellent reliability
Dual lamp system
The use of two lamp
systems increases
brightness and eliminates
the need to interrupt a
presentation if a lamp
burns out (in dual lamp
operation mode).
AC lamp
Newly developed AC lamps with full 210
watts of power offer excellent brightness and
greater reliability than other types. A new lamp
drive system also lowers the stress on the lamp
electrodes while the lamps are lit. The new
lamps have a lifetime of approximately 3,000
hours, which is reassuring
for applications where the
projector is frequently
used. The AC lamps also
minimise colour
irregularities.
Liquid-cooling system
Panasonic's original liquid-cooling system
directly cools the DLP™ chip, which extends
PT-D4000E performance and attains a high level
of reliability. It also enables operation in
temperatures up to 45˚C/113 ˚F for use in a
wider variety of environments, and maintains a
more stable performance even in harsh
conditions while keeping the operating sound
down to a quiet 29 dB*.

Micro cut filter
A filter in the air intake section traps dust
particles that are 10 microns* or larger. By
capturing approximately 7 times as much dust
as conventional filters, it guards against optical
blocks and reduces the penetration of dust into
to the interior to provide
stable operation by, for
example, preventing
drops in brightness.
*10-micron dust = lint,
pollen, etc.
Dustproof design
with sealed optical block
The effect of dust has been minimised by
completely sealing the optical block.The dustfree
design helps ensure that this DLP™
projector will continue to deliver crisp, sharp,
high-resolution images over an extended
service life.
Flexible system installation
Lens-centred design
A lens-centred, symmetrical design provides
flexible system layout, eliminating the need for
any special considerations when planning the
installation site.
Horizontal/Vertical lens shift
A wide adjustment range of the horizontal/
vertical lens shift assures distortion free images
and adds convenience and versatility.
(Horizontal : manual, Vertical : powered)
Optional lenses for
various venues
Five optional lenses with different throw
distances are available in addition to the
supplied lens. These powered zoom/focus
lenses enable the projectors to perform
superbly in an array of projection environments.
Multiple terminals
The PT-D4000E has an array of terminals-two RGB inputs including a 5-BNC connector, serial
in/out, one S-video inputs, two remote in, one remote out, DVI-D and control capability-to support a
broad range of projection needs HDCP. (High-Bandwidth Digital Content Protection) compliant.
Using the serial terminal(RS232C),it is also possible to connect and operate AMX and Crestron
control systems with ease.
Web browser control/monitoring
and e-mail message alert
Anybody can operate the PT-D4000E by remote
control or monitor its status
over a LAN network, because it
is all done using the
computer’s familiar Web
browser. Furthermore, the
PT-D4000E sends an E-mail
message to notify the operator
when an error has occurred, or
a lamp needs to be replaced.
Control panel and
wireless remote
control
The rear control panel allows for easy
operation when the PT-D4000E is set
on a desk or floor. New wireless
remote control with longer
transmission capacity of 30 m.
PJLink™ compatibility
The LAN terminals support PJLink™ class 1
connection. Control with the same specifications
is also possible when used in a multi-projector
system with
projectors of
another brand.
Easy lens replacement
The PT-D4000E uses the bayonet system, so
lenses attach and detach with one-touch ease.
