HP Digital Projector xb31/sb21
Designed for the business professional who needs
to project a high-quality image with ease.
Quality image
• For the highest-quality image. The HP Digital Projector
xb31 provides industry-leading brightness and the
highest resolution for impressive presentations, in a
micro-portable weight that is still light enough to
carry easily from room to room.
• Easily adapts to any venue. Both HP digital
projector models are equipped with built-in, full-screen
NTSC/PAL/SECAM video capability, and compatibility
with S-video, composite, component and HDTV terminals
plus SXGA (xb31 model only), XGA, SVGA, VGA
and Mac from one MD-I input terminal.
• Industry-leading brightness in any setting. Even
with the room lights on, your audience will see your
presentation with optimal clarity—the HP Digital
Projector xb31 features 1500 lumens.
• Simple presentation setup. Equipped with automatic
image synchronization for easy tracking, frequency
and position adjustment.
• Sharp, clear, accurate. Your presentation will look
as good projected as it does on your computer
screen with a TI DLP™ light engine, True XGA resolution
(1024 x 768 dpi with the xb31 model) and high
contrast ratio.
• Simple device setup. These HP digital projectors
automatically detect computer signal input and resize
images to a full screen, giving users the flexibility
they need to switch sources quickly and easily for
any presentation.
• Flexibility. A wireless remote control with USB mouse
function and a laser pointer give you the freedom to
move about the room and engage your audience.
• Lighter than most laptops. At just over two pounds, the
HP Digital Projector sb21 is designed for the mobile
professional—it lets you present a high-quality image
in a compact design that won’t weigh you down.
• You don’t give up brightness. This micro-portable
projector that fits into a purse or briefcase pouch
also projects a bright, sharp, clear image with
1000 lumens, True SVGA resolution (800 x 600 dpi
with the sb21 model) and a high contrast ratio.
• Perfect partners. An HP digital projector combined
with an HP notebook computer help you stay productive,
mobile and successful, and they both feature HP
reliability and compatibility for worry-free performance.

Superb imaging quality—what you see on your
laptop is what you see projected on the screen!
If your presentation looks good, you look good.
Whether pitching a new product, describing a design’s
progress, providing training or presenting financial
results, you only have one opportunity to engage and
convince your audience.
HP digital projectors are perfect for mobile professionals
—presenting in a variety of rooms onsite or around the
world—who demand a projector that will deliver polished
and professional presentations with a high-quality
image. These lightweight, easy-to-use projectors provide
uncompromising image brightness, contrast and resolution,
assuring that you and your presentation get results.
HP helps you fulfill the high standards that the fast-paced,
competitive marketplace has established. Photographs
project clearly with accurate colors, CAD drawings and
plans are projected with high resolution—even the most
detailed spreadsheets are easy to read—and your
presentation can include both digital and analog input.
Plus with the HP digital projectors’ quiet performance
and ability to project vivid images even with the room
lights on, you can stay engaged with your audience,
lead support exercises and get your messages across
without raising your voice.
Complete mobile solutions from a trusted partner
Customers around the world count on HP to provide
business-critical support that gets results and contributes
to business success. The HP digital projector complements
the HP product portfolio, including the entire HP Omnibook
notebook PC line, HP Jornada handheld PCs, HP’s
portable Deskjet printer and business desktop PCs.
For easy compatibility, HP Digital Projectors work with
any notebook—PC or Macintosh—but you will benefit
from optimized performance when you use it as part
of an HP mobile solution. When combined with the HP
Omnibook 500 or 6000 notebook PC, the “presentation
ready” mode hot key automatically adjusts power
management and disables screen savers while locking in
the signal to the projector. One button is all it takes to
make your HP Omnibook talk seamlessly to your projector.
And with HP digital projectors you are assured the
highest image quality with “no hassles” reliability. HP
has developed the industry standard for high-resolution
printed images and scanning technology and now you
can count on those same high-quality images “printed
to the screen.” Plus, with HP’s reputation for reliability
and the digital projectors’ two-year expedited repair
warranties, you can focus on your presentation and let
HP take care of the rest.
The freedom to connect with your audience
Industry-leading contrast ratio, bright imaging and accurate
colors capture and keep the attention of your audience and
project the best image of you and your presentation:
• 1800:1 JBMA1/400:1 ANSI2 contrast ratio provides
high definition and clear details.
• DLP™ light processor allows maximum brightness in
a small, lightweight size.
• Image is bright enough to be effective even in rooms
with the lights on.
• HP digital projector technology provides great
color matching.
• Quiet 35 dBA noise level allows you to hear questions
and comments and to be heard without raising your voice.
• Full-functionality remote control allows you to control your
presentation while staying engaged with your audience.
The lightweight, small size and versatile connections
allow you to pack, go and present whenever and
wherever you need to:
• Choose from the micro-portable xb31 at 3.5 pounds
or the sb21 at 2.2 pounds.
• Connect to any input source—S-video, composite,
component and HDTV terminals, and one MD-I terminal
for SXGA/XGA/SVGA/VGA/Mac compatibility (SXGA
in xb31 only).
