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.
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.
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 industryleading 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 technology story:
HP Visual Fidelity and
Wobulation
HDTV and HP Visual Fidelity
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 enhancement, scene-by-scene contrast adaptation keyed
to the room’s ambient lighting, and a 3D colorenrichment system.
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
each individual pixel for a cleaner, sharper image.
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.

Microdisplay TV 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 technology into new and dazzling consumer products.
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.
HP engineers simulated applying the same principle
to “droplets” of light, with exciting results. Same
size spots, yet dramatically improved image quality.
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 without expensive modifications, like changing the light
modulator or increasing pixels.
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 management 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
™
delivers thrilling sound.

HP MDTV:
HP MDTV features
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.
