Vivitek unveiled two new portable projectors at the 2010 InfoComm show, the D330MX ($899 MSRP) and D330WX ($999 MSRP). Weighing in a mere 3.2 pounds, these DLP projectors offer a 3000 lumens of brightness and a reported contrast ratio of 2500:1 (though we suspect that's probably a little inflated).
The Vivitek D330MX has an XGA native resolution (1024 x 768), with inputs for VGA, composite, and S-video. For $100 more, the D330WX has a WXGA resolution (1280 x 800) and an additional HDMI input. They join the relatively small line-up of "portable projectors" offered by Vivitek, though they will be the brightest in the series.
