Bright 1200 ANSI Lumens, High 400:1
Contrast Ratio
Contrast Ratio
The PT-LC75E and PT-LC55E deliver super-bright per-
formance with 1200 ANSI lumens, thanks to a newly-
designed, high-performance optical system and high-
efficiency 160-W UHM™ lamp. The high contrast ratio
of 400:1 ensures that images are sharp, crisp, and
easy to see. Both models also provide excellent bright-
ness uniformity of 90%.

Excellent Colour Rendition
The use of advanced 10-bit digital gamma correction
circuitry with the latest algorithm gives the
PT-LC75E and PT-LC55E naturally vivid, uniform
colours and smooth image gradation. Plus, full compati-
bility with the “sRGB” standard colour space adds more
accurate colour reproduction to your presentations. The
PT-LC75E also delivers outstanding moving pictures
thanks to a Digital Cinema Reality (DCR) circuit and
3-dimensional comb filter*.

One-Touch Auto Setup — Ready in Just
1.5 Seconds
1.5 Seconds
The One-Touch Auto Setup function with digital key-
stone correction saves adjustment hassles. Panasonic’s
original built-in gravity sensor determines the projec-
tor’s angle relative to the floor (up to 30 degrees) and
corrects for keystone distortion accordingly. This makes
set-up super-easy: Just aim the projector at the screen
and press the Auto Setup button. The projector handles
all picture adjustments, from phasing and dot clocks to
vertical and horizontal position. Our newly designed
algorithm slashes set-up time to just 1.5 seconds — half
the time of our previous models.

Extra Short-Throw Lens
The PT-LC75E and PT-LC55E are equipped with a
large-diameter, extra short-throw lens that shortens the
necessary projection distance by 25%. Conventional
projectors often have to be positioned in the middle of
the meeting table, with considerable distance between
the lens and the screen. The shorter projection distance
of the PT-LC75E and PT-LC75E saves space. For
instance, 2.4 m or less is needed to project an 80-inch
diagonal screen, allowing the projector to be placed at
the front of the table. This convenient feature enables

Quiet Cooling Fans — Only 30 dB
Whisper-quiet fans and switchable dual-mode operation
combine to reduce operating noise to 30 dB (in stanard
lamp power mode). A newly developed exhaust fan also
minimises light leakage.

Accepts Up to Two RGB Inputs and One
RGB Output
RGB Output
Two RGB inputs eliminate the need to re-connect
equipment when giving two different presentations back
to back. The RGB2 terminal can also serve as a loop-
through monitoring terminal for the RGB1 input. For
instance, an instructor in a
classroom can use this to
give a presentation on a
large screen while following
the same images on a PC,
eliminating the need to keep
looking at the screen behind.

Unique Index Window
Any image in the presentation, RGB or video input, can
be frozen, stored in memory, and displayed on the left
side of the screen as an Index Window, while the dis-
play of subsequent images continues on the right. This
can make presentations much easier to understand.

3,000-Hour Lamp Life
The user can select from Standard and High lamp
power modes. Designed for use in dark rooms,
Standard mode uses a lower lamp power that minimis-
es energy consumption and lengthens the lamp life up
to 3,000 hours (2,000 hours in high lamp power mode).

The sRGB Standard
Colour Space
Colour Space
sRGB is a new standard
that assures uniform
colour expression among
scanners, monitors, pro-
jectors and other imaging
equipment. Applying the
sRGB standard minimises
hue deviations to ensure
the same high level of
colour reproduction in
each device.
