NEC NP43, aren't as impressively light as LED-based sub-three pound projectors, but they offer a lot brighter image. The NP43, for one, lives up to its 2300 lumen rating while weighing only about a pound more than a typical 500-lumen LED model. Beyond that, it offers a high quality data image and some welcome conveniences for portable use.
In most ways, the NP43 sticks to the basics. It's built around a 1024x768 DLP chip and skips some features that are rapidly becoming all but standard. In particular, it lacks an HDMI port, which limits it to analog connections, and it isn't 3D ready. However it goes beyond the basics in other ways, with a 1.2x zoom, auto keystone, and, most notably, auto focus.
What these extras have in common is that they all enhance the NP43's portability by making setup easy. Simply connect the power cord and cables, turn the projector on, and adjust the image size with the zoom control. In my tests, the auto sync worked well enough so I couldn't improve on it with manual adjustments, and the auto keystone and auto focus took care of everything else. For anyone who needs a bright, portable projector as a traveling companion, the NP43's combination of weight, brightness, image quality, and easy setup makes it a strong contender, fully worth the $899 street price.
