The 3D Reform projects images from an angled position. A next generation mobile projector supporting a LAN environment.
The highest freedom in setting up the projector*1. With the 3D Reform function that is NEC's newly developed technology, it is possible to project images from a position in a range of up to 40 degrees vertically and 34 degrees horizontally from the projection angle.
A newly developed NEC chip provides the 3D Reform function, a keystone correction feature that corrects trapezoidal distortions, something which was beyond the capabilities of traditional "up-down-left-right" correction functions. With this function, more vivid images can be projected. If the projection is distorted, simply set the four corners of the screen to square the picture. This allows greater freedom in setting up the projector, because it can now be set up at an angle in relation to the screen. You can set the projector anywhere it does not become an obstacle, and no longer needs to be placed right in front of the screen.
With the Geometric Correction function capable of projecting square images onto cylindrical or spherical screens, applications for large-sized projection will be expanded.
* Under some environmental conditions, this projector may not be set up.
A PC card slot is provided to support wireless/wired LAN and PC-less presentations.
In case of a conference with many participants, it is possible for them to transfer data from their own PC's and project images directly without reconnecting cables. By installing an optional wireless LAN card, you can proceed with conferences without interrupting the discussion. It is also possible to use multiple projectors simultaneously to project images in a large venue.
By using a commercially available LAN card, you can collectively monitor and control the projector's state (confirmation of the time duration for using the lamp, On/Off of the power etc.) from your PC through the network. Furthermore, you can send a notification of the lamp lifetime or error messages to an e-mail address set previously.
You can project images without connecting the projector to a PC by recording documents onto a flash memory card and installing it in the PC card slot. It is convenient since it is not necessary to bring a PC. (Acceptable formats are JPEG, BMP, TEXT, HTML, and INDEX*.)
* A file format produced with the Dynamic Image Utility stored in the attached CD-ROM.
* Do not install any compact flash type card other than the memory card in the equipment. If such cards are installed in the equipment with a PC card adapter, the card may be damaged.
Brightness of 2000 ANSI lumens at a contrast ratio of 2000:1
Since high brightness of 2000 ANSI lumens is achieved, it is possible to project sufficiently clear and vivid images even in a bright room. Furthermore, the high contrast ratio of 2000:1 is achieved by introducing the advanced DMD and a newly developed optical system for optimizing the image. As a result, contrast between black and white becomes clearer and the capability for expression has improved drastically.
Low noise operation less than 29 dB is achieved. (With Lamp Eco Mode)
By combining a feedback type fan controlling circuit to set suitable cooling conditions according to the operating conditions and a newly developed motor, quietness of 29dB is achieved with Lamp Eco Mode. No noises will disturb your conference. (32 dB in Normal Mode.)
Its low power consumption and a max. lamp life of 3000 hours contribute to saving energy.
Power consumption of 280 W is achieved by introducing a newly developed high-efficiency power supply and high-efficiency engine. Power consumption in the Standby Mode is as low as 0.6 W or less.
By using the Lamp Eco Mode, lamp life is extended to 3000 hours, running cost and labour for replacing lamps can be saved. (Brightness in the Lamp Eco mode is 1600 ANSI lumens.)
Security Function preventing use by unauthorized persons
By setting passwords, it is possible to prevent from changes in the settings of the projector without permission. By registering a flash memory card as a protection key, it is impossible to project if the registered card or USB memory is not installed in the equipment when the power is turned on.
USB memory and a USB memory card reader can be used.
Not only the flash memory card but also USB memory can be connected to project images stored in USB memory or used as a protection key. Furthermore, by connecting a commercially available USB memory card reader, you can handle various kinds of data in memory cards or use various kinds of memory cards as a protection key.
For the available USB memory and USB memory cards, please refer to this.
The pull-down operation menu is easy to understand. If you use a USB mouse, the operation becomes easier.
Various operations can be easily with using understandable pull-down menu like PC operations. You can choose either the Basic Mode as displaying a basic operation menu or the Advanced Mode in which you can make adjustments to details. It is also possible to customize the menu to display frequently used functions. By connecting a commercially available USB mouse, you can also access the menu with it.
Furthermore, with the chalkboard function, you can draw on the projected image directly to make more impressive presentations.
A soft case is attached as a standard option.
A soft case for containing the projector is a standard option.
It can contain cables along with the projector.
The Multifunctional Presentation Wireless Remote Controller with a built-in laser pointer* is attached.
All basic operations required during a presentation are concentrated in the Wireless Remote Controller. You can operate various operations, including mouse operations of a PC, as well as controlling the projector with the simple operation of the Wireless Remote Controller. The signal receiver is located at both the front and the rear of the Wireless Remote Controller. Since there are no limitations to the position of the presenter, you can concentrate on your presentation.
* This product is compliant with Class 2 based on laser standards (JIS C 6802:1998)
