Major Features

⬛Ultra-light (1.6 kg), high brightness mobile projector with wireless, computer-less pre-

sentation function

The efficiency of the use of light is improved thanks to the combination of the DLP™ system and a unique optical design. The three primary colors necessary for expressing colors (red, green and blue) are produced with a single DMD (an ultra-high precision digital device), thereby achieving high brightness, compact size and light weight. In addition, wireless LAN technol- ogy enables wireless presentations without the need to connect the projector to a computer using an RGB cable. The image viewer function can be used to present PowerPoint files (including picture files and animations) stored on a CF card without a computer.(*1)

*1. For details, refer to the “Image Viewer / Network” manual.

⬛Sharp, clear picture

The DLP™ display system affords RGB color fidelity and inconspicuous gaps between the individual dots, thereby permitting the display of small characters and diagrams with distinct clarity.

⬛High contrast ration of 2000:1

Use of a new generation of DMD devices has given birth to an amazing 2000:1 high contrast ratio.

By widening the difference of brightness between black and white, you can see a degree of sharpness that is greater than just the brightness based on specifications.

⬛Great moving image playback capabilities using the same principles as DLP Cinema™

technology

Plus DLP type projectors have the same makings as the DLP Cinema™ technology used in movie theaters. Because of their extremely fast response, even images with much movement – sports, movies – play smoothly without blurring.

⬛Security lock function

The lock can be set so that a password must be input when the projector is started up. Without the correct password, no operations other than turning the power on and off can be performed. This function effectively protects the projector from unauthorized use.

⬛Powerful functions for presentations

A wide variety of easy-to-set functions have been built into the projector, from a digital keystone correction function (used when making settings) that corrects picture distortion, to an auto adjustment function that automatically identifies the PC signal.

There is also a built-in “Presentation Timer” function for further presentation convenience.

⬛Beautiful reproduction of high-quality images from DVD

Faithful reproduction of color tones gives rise to the display of natural images. High-quality images such as those from DVD and digital high-definition television broadcasts bring out the display capabilities that are an essential strength of the DLP™ display system projector.

⬛Digital/analog RGB input

by using a DVI cable to connect the projector with a personal computer equipped with a DVI connector. This will allow fully digital pictures to be enjoyed.

⬛Econo-mode switch function for the lamp output

Using the lamp Econo-mode will extend the life of the lamp and lower the power consumption.

By switching the lamp mode to suit your operating environment, you will save on lamp cost as well as contribute to energy conservation and ecology.
