							PT-LB75NTU
PT- LB75U
LCD Projectors
Elegant Styling, All-Round Versatility 
						

							Panasonic’s new LCD projectors—
PT-LB75NTU and PT-LB75U—are ideal for
anyone who wants an easy-to-use projec-
tor but doesn’t want to compromise on
image quality and performance. The highly
advanced dust-resistant design minimizes
image degradation by reducing the entry
of dust into the unit. The design includes
“gapless” touch-sensor controls on the
top panel and an airtight structure thatconcentrates the air intake into a single
location. Panasonic’s original Daylight
View 4 feature provides bright, crisp
images even in brightly lit conditions.
The PT-LB75NTU also include an easy-to-
use wireless function. In short, the 
PT-LB75NTU and PT-LB75U incorporate
the unique essence and versatility of
Panasonic projector technologies while
maintaining an elegant design.

Dust-Resistant Structure Minimizes
Image Degradation
After a projector has been used for some time,
dust particles that have entered the interior
accumulate on the optical components and
lower performance. The PT-LB75NTU/LB75U
prevents this with a unique dust-resistant
design. This totally redesigned package has
touch-sensor controls that eliminate the gaps
around conventional buttons and a lens cover.
The design also incorporates a cover that pro-
tects the zoom/focus ring when not in use.
These features combine to help reduce dust
entry. Inside the projector, the airflow is effi-
ciently controlled by a structure that reduces
contact between external air and the optical
components. This all works together with the
high-performance Micro Cut Filter to minimize
image degradation.

Images Even in Bright Surroundings *

The PT-LB75NTU/LB75U features Panasonic’s
Daylight View 4 technology. Sharp edges are
achieved with the new “Edge Enhancer Con-
trol” and “Gamma Curve Control.” Remarkable
detail is provided and perceived brightness and
contrast are enhanced, so images appear
crisp, vivid, 3-dimensional and easy to see
even in brightly lit rooms. Daylight View 4 also
includes a built-in ambient light sensor that
automatically detects room brightness and
adjusts operation accordingly.

							Easy Wireless Projection
With the wireless capability of the PT-LB75NTU,
you don’t need cables to connect a PC, either
Windows
®or Mac®. That means it’s easy to
bring in a laptop (with a wireless LAN function)
and deliver a smooth, hassle-free presentation.
You can make the connection settings quickly
and easily using the supplied Wireless Manag-
er ME 5.0 software. When the presentation is
finished, Wireless Manager restores the PC to
its previous LAN settings, so the PC is ready
to reconnect to your LAN.
Multi Live Mode: Wireless Projection
from Multiple PCs
The PT-LB75NTU provides a host of convenient
wireless functions, including Live mode and
Multi-Live mode. In Live mode, the image pro-
jected is identical to the image seen on the PC
screen. In Multi-Live mode, you can wirelessly
connect with multiple PCs.
Other wireless functions include Wireless
Prompter (Secondary Display Transmission),
selective area transmission, and a 16-window
index style that lets you project images from
up to 16 PCs at the same time. Wireless
transmission is possible from one PC to a
maximum of eight projectors at a time.
Selective Area Transmission
By circling any area of the image, you can
specify the necessary information to enlarge
and display that area on the projection screen.
Projector Signal Map
The signal map graphically shows the strength
of wireless connection signals. This is conven-
ient, for example, when several projectors are
being used in adjacent school classrooms
because it lets the user know which projector
is to be used.
Extended Mac OS X Compatibility
In addition to its Windows Vista
®compatibility,
Wireless Manager ME 5.0 is fully compatible
with Mac OS X 10.4/10.5.*

Versatile Wireless Presentation
To begin wireless projection, simply use the
control panel (launcher) displayed in the PC
window.The same graphics
used on the projec-
tors remote control
can be displayed on
the PC screen. This
makes it easy to
operate the projector
right from the PC,
without having to use
the remote control.

							Elegant, Compact Design
The PT-LB75NTU/LB75U has a sleek and ele-
gant appearance that matches its high-per-
formance capabilities. The projector blends well
with virtually any room interior, whether it is
placed on a desktop or mounted on the ceil-
ing. At 2.96 kg, its light weight and compact
design also make it easy to move around.
Quiet Operation
The PT-LB75NTU/LB75U’s operating noise is
reduced to 29 dB,*
4which minimizes noise
interruptions during meetings or lectures.
Quick Operation
• Three-Second Speed Start: With Speed
Start, the image appears in about three sec-
onds after you press the power button.
• Auto Search: When a source is connected
and you switch the unit on, it automatically
detects what kind of source is connected and
begins projection.
• Real-Time Keystone Correction: The pro-
jector automatically senses if you adjust its
angle (vertical direction) during operation and
instantly makes whatever keystone correction
is necessary for optimum viewing.
• Direct Power Off: Because the cooling fan
keeps operating until the lamp is cooled, you
can disconnect the power cable and move the
projector as soon as your presentation is fin-
ished, or turn off the rooms main power when
the unit is mounted on the ceiling.
Ceiling-Installation Capability
The projector can be permanently installed on
the ceiling by using the optional ET-PKB80
ceiling mount bracket. Abundant Connection Terminals
Designed for versatility, each projector comes
equipped with a host of connection terminals.
The RS-232C specifications are the same as
in previous Panasonic models, so replacement
is quick and easy.
Easy Lamp Replacement from the Rear
For easier maintenance, you can replace the
lamp from the rear. The lamp is easily
replaced even after the projector is installed on
the ceiling.
Easy-to-Use Remote Control
The control range and distance have been
extended compared to previous models, and
the buttons are now larger and easier to use.

Ecology-Conscious Design
Panasonic works from every angle to minimize envi-
ronmental impact in the product design, production
and delivery processes, and in the performance of the
product itself over its life cycle. The PT-LB75 Series
reflects the following ecological considerations.
• Lead-free solder is used to mount components
to the printed circuit boards.
• No halogenated flame retardants are used in
the cabinet.
• No styrofoam is used in the packing materials.
• Lead-free glass is used for the lens.
All PT-LB75 Series projectors are care-
fully manufactured at the Panasonicfactory in Japan, under strict quality
control. This is another, very important
advantage of a Panasonic projector.
