PJ551D- 0.55” DDR XGA DMD DLP, 1280 x 1024, 2300 ANSI
The ViewSonic PJ551D projector delivers amazingly crisp digital images at qualities only a DLP projector can achieve. Weighing in at just 2.8kg with 2200 ANSI LUMENS and a 2000:1 CONTRAST RATIO, this portable projector makes it easy to give multimedia lessons in the classroom or dynamic presentations in the boardroom. Multiple preset presentation modes, an increased ±40 degree digital vertical keystone correction and optical zoom ensure the best possible image regardless of location. With up to 4000 hours of lamp life, low cost replacement lamps, filter-less design and a non-degrading DLP light engine, the PJ551D has one of the best “TOTAL COST OF PROJECTION” ratios in the industry. The PJ551D makes giving presentations enjoyable for educational and business users alike.
Bright in virtually any setting
Packs 2200 ANSI lumens in just 2.8kg, and with a high 2000:1 contrast ratio, your presentations are guaranteed to be vibrant – even with a lot of ambient light.
DLP® technology
Latest Brilliant Colour Technology delivers stunning all-digital clarity with life-like colour, sharp graphics and outstanding video. The sophisticated 5-segment colour (RGBWY) wheel provides greater colour accuracy than standard DLP projectors with a 4-segment colour wheel.
Lowest “Total Cost of Projection”
Top cover lamp replacement ensures easy and cost-effective maintenance, while prices for replacement lamps are incredibly low. High performance is guaranteed by 3500 hours of lamp life or 4000 hours in eco mode! In addition, filter-less design means there is no need to clean or change filters.
Protection & Personalisation
Assign a PIN code to prevent unauthorised use or theft, and customise your start-up screen to suit your needs.
Ease of use
The PJ551D comes with a suite of electronic features to make the set-up process easy. Electronic keystone correction (+/- 40 vertical degrees) maintains a squared image, while 7 preset modes adapt to any environment – including chalkboard modes for educational uses. In addition, this projector’s automatic signal detection reduces set-up times, while a new button on the remote enables easy toggling between high brightness and true colour mode.
Wireless projection (WPG-150)
Optional WPG-150 provides unparalleled wireless performance for data and video applications. The PJ551D projector networks seamlessly via wireless connections to a notebook or desktop PC.
