HP makes 2.2-pound DLP projector
Hewlett-Packard Co. makes one of the market's lightest digital light processing projectors, the 2.2-pound sb21.
'Projectors used to be specialized audio-visual purchases,' North American marketing manager Anneliese Olson said. 'Now they're shifting to the computer channel.'
The $2,499 sb21 and the larger $3,699 xb31 use compact, 1,500-lumen bulbs with an expected life of 2,000 hours. The special bulbs are available only from HP resellers, but the projectors work with any vendor's Microsoft Windows, Pocket PC or Mac OS systems, Olson said.
When paired with HP's Omnibook 6000 or Omnibook 500 portable computers, the projectors turn on immediately in a hot-key ready mode. They display 1,024- by 768-pixel XGA or 800-by-600 SuperVGA resolution. They have elevator feet, optical and digital zoom functions, and cooling fans that point away from the audience.
Olson said the projectors come in a rugged magnesium-alloy casing with three types of power cords for different voltages. Although the sb21 is only 2 inches high, HP designed mirror optics for Texas Instruments DLP chips to trap light for a high contrast ratio.
