HP HDTV is the latest and most exciting creation
of HP Visual Fidelity technologies. It’s grounded in
HP’s decades-long history of engineering excellence
and color science leadership. And it’s infused with
our unparalleled cutting-edge technological drive
and our determination to provide our customers with
digital entertainment products that are simple to use
yet produce consistently stunning visual experiences.
Why HP High Definition?
The digital entertainment revolution is in full swing.
Digital cameras, digital camcorders, and CD
and DVD players already rule their respective
markets, empowering home consumers to easily
and affordably create, manage, and enjoy high
quality viewing and listening experiences. And
the next big wave—already roaring towards shore
and about to break—is high definition television.
HP is positioned to ride that wave with a complete
lineup of high definition TVs that will swamp the
competition with everything our customers want:
competitive pricing, unequaled ease of use, and
mind-boggling image quality.
Pioneering innovation has always been a priority
at HP (take for example, the front connect panel on
the MDTVs). Nowhere is that innovative edge more
apparent, or more crucial to the company’s industry-
leading position, than in the application of color
science to electronic technology. For more than
two decades, HP has led the way in color science.
That experience and the depth of knowledge it
represents are key to the company’s new entry into
the home digital entertainment market. HP engineers
have taken what they know about ink, and applied
it to light—the science underlying ink droplets is
surprisingly similar to that of light droplets.
The result immerses the viewer in a dazzling home
theater experience: true-to-life color combined
with startlingly crisp image quality and ear-tingling
sound, all in an attractive, easy-to-use package at
a competitive price. That’s the HP HDTV experience.

The Wobulator
Images without Wobulation (top) are dramatically improved by
two-position Wobulation, which doubles the resolution.
Microdisplay TV and Wobulation
The technology story:
HP Visual Fidelity and
Wobulation
Wobulation is a funny name for a great technology.
And it’s another great example of HP ingenuity at
work—leveraging our industry-leading inkjet tech-
nology into new and dazzling consumer products.
HDTV and HP Visual Fidelity
Here’s how: both printers and digital projectors
create a color picture from a matrix of primary
color points. Historically, print resolution was
increased by placing more and overlapping ink
droplets within the same size grid; initially,
300 x 300 dot-per-inch (dpi) resolution became
600 x 300 dpi. That yielded significantly better
image quality from the same size dots of ink.
Thanks to HP’s Visual Fidelity technologies—the
power behind the picture—our HDTVs deliver
unrivaled image quality and color brilliance.
In LCD and plasma models, HP Visual Fidelity
technologies provide an advanced video pipeline
that combines photorealistic sharpness enhance-
ment, scene-by-scene contrast adaptation keyed
to the room’s ambient lighting, and a 3D color-
enrichment system.
HP engineers simulated applying the same principle
to “droplets” of light, with exciting results. Same
size spots, yet dramatically improved image quality.
HP Visual Fidelity includes technologies such as
Wobulation, which doubles the pixel resolution to
provide brilliant, crisp, true-to-life images. (See
illustration, above.) The lamp is brighter, offering
more accurate, vivid colors and an ultra-wide
viewing angle. And DLP™ technology fine-tunes
each individual pixel for a cleaner, sharper image.
In fact, the resulting light-imaging technology—
Wobulation—doubles the addressed resolution of
non-Wobulated, digitally projected images, without
diminishing their renowned crispness. This technology
virtually eliminates the screen-door effect commonly
seen in other displays. And it’s accomplished with-
out expensive modifications, like changing the light
modulator or increasing pixels.
All HP HDTV models feature high contrast ratios for
brighter lights and deeper darks. That means truer
blacks—enhancing image sharpness and power,
whether the scene is action-packed or brightly lit
or darkly shadowed. It means subtler color detail.
And it means increased tolerance of ambient light.
Better resolution, eye-popping picture quality,
virtually no increase in cost. So, HP customers who
choose our MDTVs get the best possible HDTV
viewing experience at a price they can afford.
The bottom line? A viewing experience like no
other, rich with stunning detail and true-to-life colors.

Industrial design
Form, function, and style
The HP HDTVs are as beautiful as the images they produce. Stylishly thin, the HP Plasma and LCD TVs
complement any décor and take up less space than a traditional TV. And they’re remarkably easy to
use; our intuitive onscreen menus and ergonomic remote controls turn typical setup and operation
nightmares into sweet dreams.
The satin-finished metal framing and cabinetry of
the HP MDTVs is mirrored in the optional matching
stands, as is their unique integrated cable manage-
ment system. HP MDTVs feature a revolutionary
lighted, front-mounted quick-connect panel that
allows A/V cables to be easily connected from the
front, then hidden from view. Thumbnail source
selection (up to ten sources) and preset customizable
video and audio modes are key to their unparalleled
ease of use. And their built-in 85-watt audio system
with integrated subwoofer and SRS TruSurround
XT™ delivers thrilling sound.

HP MDTV features
HP Visual Fidelity
•HP Wobulation uses resolution doubling to produce
clean, crisp images and virtually eliminates
screen-door effect.
•The DynamicBlack™ aperture enhances resolution
for a smoother picture, vivid colors, fine detail,
and darker blacks.
•The white point in these TVs is truly white, making
it possible to see natural subjects in natural colors.
•The 1080p models (md5880n and md6580n)
are capable of receiving and displaying native
1080p compressed and uncompressed HD content
(through HDMI at three frame rates).
•HP-enhanced DLP technology and a brighter bulb
sharpen contrast ratios while delivering more vivid
color and less fall-off.
a new approach
While all DLP™ TVs share common characteristics,
you can really see the differences in HP MDTVs in
the areas of picture, sound, connectivity, styling,
and ease of use.
The 720p TVs—50-inch and 58-inch models—are
entry-level, offering great picture quality and ease
of setup. The higher end 1080p TVs, the 58-inch
and 65-inch models, feature advanced picture
technology, and are two of the few 1080p TVs on
the market capable of receiving and displaying
native 1080p compressed and uncompressed HD
content through HDMI at three frame rates. This
gives the consumer the opportunity to select from
price and feature options to fit individual budgets
and taste. HP is future-proofing the consumer’s
expensive investment.
Image quality
•Picture uniformity across the screen makes for
an ultra-wide viewing angle, both horizontal
and vertically.
•The screen’s flatness and focal length improve
image sharpness and virtually eliminate glare
and reflection.
•The brighter 150-watt DC UHP lamp produces
more vivid color, more contrast, and less fall-off,
with no flicker. The picture is rich with detail,
even in daylight.
•The color wheel and lamp work together to deliver
more natural colors, especially noticeable in
realistic skin tones and truer greens.
•Color temperature is lower and warmer overall,
for a more true-to-life picture.
Connectivity
•Lighted, front connection panel provides inputs
for common sources such as a TV antenna and
cable service, a DVD player, an audio/video
receiver, a VCR, a personal digital video recorder,
an HD camcorder, a video gaming device, a
personal computer, and a satellite receiver.
•The 1080p TVs are Digital Cable Ready with an
integrated CableCARD slot. The 720p TVs allow
for an optional CableCARD tuner module,
eliminating the need for a separate cable box.
HP Visual Fidelity: the science of great image quality
HP’s rich assets and printing technology intelligence
have been employed to transform the art and science
of display. When we say “HP Visual Fidelity,” we’re
talking about HP technologies that work together
to provide outstanding image quality and color:
•HP Wobulation/resolution enhancement
•Color science
•Image processing and rendering
•Illumination
•Viewing experience

5.1-channel surround system A speaker setup that places one speaker above
or below a television, on each side of the display, and two beside or just
behind the listener (standard surround). A subwoofer is usually placed to the
front of the listener. A surround system creates a more immersive, realistic
sound experience—the more speakers, the richer the sound.
7.1-channel surround system A speaker setup that places one speaker above
or below a television, one on each side of the display, two beside or slightly
behind the listener (standard surround), two behind the listener (surround
back channels), and a subwoofer to the front of the listener. A surround
system creates a more immersive, realistic sound experience—the more
speakers, the richer the sound.
480i (480-line interlaced scan) The vertical resolution of standard-definition
broadcasts, and the original resolution technology. Picture is 704 x 480 pixels,
sent at 60 interlaced frames per second (30 complete frames per second).
480p (480-line progressive scan) The vertical resolution of standard-definition
and some enhanced-definition broadcasts. Picture is 704 x 480 pixels, sent
at 60 complete frames per second.
720i (720-line interlaced scan) The vertical resolution of some high-definition
broadcasts. Picture is 1280 x 720 pixels, sent at 60 interlaced frames per
second (30 complete frames per second).
720p (720-line progressive scan) The vertical resolution of some high-definition
broadcasts. Picture is 1280 x 720 pixels, sent at 60 complete frames per second.

D
Electronic program guide A program menu on
HP entertainment products, such as the Digital
Entertainment Center and Media Center PC, that
displays chronological, and automatically updated,
program listings.
Digital light processing (DLP™) A Texas Instruments
display technology that uses a Digital Micromirror
Device (DMD) to create and project vibrant, high-
definition images via either television or a projector.
De-interlacing A feature that improves picture
quality, producing a film-like richness. Sixty frames
per second are shown as opposed to the standard
30 frames per second. Also called “line doubling.”
F-G-H
HD televisions (see illlustration above) Any TV set
with native support for at least 720p is considered
an HDTV. But will HD programs viewed on a
1080p set look better than they do on 720p mod-
els? The answer depends on the type of HD
program. No HD shows are currently broadcast in
1080p; some are recorded in 720p, others in
1080i. 1080i content can be broadcast in 1080p
using a de-interlacer. A 720p set de-interlaces the
1080i image and then scales down the 1080 hori-
zontal lines to 720 lines; a 1080p set only has to
do the first step, so it should produce a better-look-
ing image. But 720p content is likely to look better
on a natively 720p set than on a 1080p model
that has to scale the image up.
Digital coaxial cable Carries a multi-channel
audio signal between digital or electronic devices,
separating sound into speaker-specific signals.
Dark video enhancement Enhances details in
dark scenes.
Digital tuner A set-top or built-in television tuner
that receives digital television signals. Also called
“digital receiver.”
Dolby Digital A form of digital audio coding
that efficiently encodes sound to a digital format,
especially when multiple audio channels are
required.
HD-Built-in vs. HD-Ready Some HDTVs (HD-Built-in)
have a built-in tuner to receive local high-definition
broadcasts, and are considered true HDTVs.
Sets without an integrated tuner are “HD-Ready”
and need a set-top box to decode the high-
definition signal.
DTS (Digital Theater System) Digital Surround
A surround sound format (5.1, 6.1, or 7.1), similar
to Dolby Digital standard, that features five to
seven discrete (independent) channels, plus a
channel for low frequency effects. See “Dolby
Digital” and also “Surround Sound.”

HD DVD (high-definition DVD) A next-generation
optical disc format developed for high-definition
video recording and rewriting. Types (red or blue
laser) and storage capacity of HD DVDs vary.
They include blue-laser DVD and Blu-ray disc.
M
Microdisplay TV A large-screen television using
rear projection technology. The newest generation
of microdisplay TVs are more lightweight and
compact than are their earlier counterparts.
HDMI (high-definition multimedia interface)
An uncompressed, all-digital audio/video interface
between any compatible digital audio/video source,
such as a set-top box, DVD player, and A/V receiver,
and a compatible digital audio and/or video monitor,
such as a digital television (DTV). HDMI supports
standard, enhanced, or high-definition video, plus
multi-channel digital audio on a single cable, and
is backward-compatible with DVI.
Motion adaptive de-interlacing Detects and
compensates for motion in pictures, reducing
contours and greatly diminishing visual noise
without reducing picture detail.
N-O
Optical cable A digital connector that carries
information optically rather than electronically, which
renders it unsusceptible to electrical interference.
HDCP (high-definition content protection) An
encryption in high-definition signals that prevents
unlawful duplication. HP’s HD demo tapes have
HDCP encoded.
Over-the-air HD programming Requires TV owners
to have an HD antenna and HD-capable TV, and
live in an area where digital television is broadcast.
HDTV ATSC tuner An internal or external over-
the-air tuner that receives high-definition television
signals. Also called “ATSC HD tuner.”
P
Personal video recorder A device that can record
and play back television in digital format, as
opposed to the analog format recorded by a VCR.
Also called “digital video recorder.”
I
Integrated HD An HDTV that has a built-in
high-definition receiver/tuner.
PIP (picture in picture) A television feature that
allows you to view multiple TV channels
simultaneously by creating one or more smaller
displays within the larger television display.
Interlaced (i) scanning A method of displaying
images from a video signal on a TV screen by filling
in every other line (the odd lines), and then filling
in the other lines (the even lines), so only half of the
set’s lines are “firing” at a given time. Interlacing
allows for greater resolution at lower bandwidth,
but it can produce flicker if you’re watching sports
or other content showing rapid movement.
POP (picture outside picture) A television feature
that allows you to view two or more (depending
on the type of POP capability the set has) TV
channels simultaneously by dividing the television
display into halves.
J-K-L
Progressive (p) scanning A method of displaying
images from a video signal on a TV screen by
filling in all of the vertical lines sequentially, rather
than in two passes, as with interlaced scanning.
Low-angle interpolation A corrective feature in HP
TVs that smoothes out the “staircase effect” caused
by viewing at certain angles.
Lumen The unit used for measuring light output,
expressed in “candelas per square meter,” or cd/m².
