Expert review by : Robin Morris (



No amount of praise can do justice to the incredible portability of NEC's LT20. At just 1kg, it's a cinch to carry for long distances - even after walking with it for an hour, the LT20 still felt as light as a feather. All too often, underweight can...

The LT20 manages to keep down bulk without compromising too much on specifications or image quality. For the travelling executive, it'll prove a welcome companion. However, size and weight will have to be your main criteria if you're to justify the...

Expert review by : John R. Delaney (



The NEC LT20 is light enough to take with you wherever you go. There are a few design tradeoffs, but the bright image helps make this a worthy road companion.

Product Specifications

The LT20 is ideal for people who need ever more flexibility and mobility. It's about the size of a paperback book and weighs only 1 kg, thus fulfilling one the most important requirements so that it can virtually accompany your every move. And that's not all: with a luminance of 1500 ANSI lumens, DLP, XGA resolution and a contrast ratio of 2100:1, the LT20 is equally impressive in its performance. With useful high-tech features such as digital trapezoid correction and onscreen menus in 11 languages, it gives you more, not forgetting its very modern and elegant design. In addition, it has remote control, Plug&Play, and intuitive controls for device functionality. It is also extremely easy to operate. In short, for unrestricted mobile presentations, this projector can hardly get any more convenient and handy.
