Projector P420X/P350X/P350W
Projector P420X/P350X/P350W


Optimal capabilities with the inclusion of lens shift, 1.7x zoom and centre lens with ceiling mount support.

Functions and Features

Features designed to make installation and maintenance easy.

Vertical lens shift mechanism to adjust the screen position

Vertical lens shift mechanism to adjust the screen position

The projector is equipped with a lens shift function that can easily move the position of the projected image up or down by rotating a dial left or right, which means that the projector does not have to be moved. The focus can also be easily adjusted using a focus lever. The keystone correction function also makes it possible to move the range up or down ±30°.

The 1.7x zoom provides excellent flexibility for installation locations

The projector supports a 1.7x zoom to cover a wide throw distance. When combined with the lens shift mechanism, this makes ceiling mountings much easier.

Ceiling mounting kit for centre lenses (option)

A geometric correction function to enable projection to a screen on an angle

When the projector is hung from the ceiling using the ceiling mounting kit (NP12CM), the lens centre of the projector is positioned at the centre of the mounting kit. This design makes it easy to determine the position of the projector.

A convenient test pattern for picture adjustment

A convenient test pattern for picture adjustment

You can check the screen projection condition while setting up the projector by using a test pattern (grid). The projector can be checked independently without having to connect image devices and output test images.

A geometric correction function to enable projection to a screen on an angle

A geometric correction function to enable projection to a screen on an angle

The Geometric Correction Tool (GCT) of included Image Express Utility Lite software enables the projection of images from a computer to screen on an angle and to screens with complex shapes.

An optional cable cover is available

An optional cable cover is available

The optional cable cover (NP01CV) can hide cables even in situations where cables standout, such as with ceiling mountings.

Equipped with a large, maintenance-free filter

Equipped with a large, maintenance-free filter

The large filter has the two-layer construction. It provides excellent dust protection and eliminates the need for regular cleaning. Just replace the filter when you change the lamp.

Advanced functionality designed for ease of operation

A USB display function for simple connection with a single USB cable

A USB display function for simple connection with a single USB cable

The USB display function lets you connect the projector and a computer with a standard USB cable to easily project computer screen images without computer cables.

“No-signal guidance” for easy cable connections

“No-signal guidance” for easy cable connections

When there is no signal being input, the "No-signal guidance" display appears on the screen. Since you know in a glance where the cable should be inserted, your setup runs smoothly.

Crestron RoomView® support

This support provides unified management, including the ability to switch the power on and off for multiple projectors connected to a network.

Supports wired and wireless LAN (IEEE 802.11b/g/n) and various network controls

Optional Wireless LAN unit

  1. For Microsoft Windows Media Connect, still and video (streaming) images are sent to projectors connected to the network. (Exceeding segments is not supported)
  2. Files in the shared folders of computers connected to the network can be viewed.*
  3. WPS (Wi-Fi Protected Setup) is supported. Projectors can be synchronized to an access point and infrastructure wireless LAN connections can be performed automatically.
  4. Includes an access point connection for improved stability of wireless LAN connections.
  5. Supports Windows Network Projector and PJ Link

Supports Virtual Remote Tool for operation of projectors from a computer

  • *Use the included Virtual Remote Tool software.

Added functions for the economical use of energy and the reduction of total cost of ownership

Equipped with an automatic Eco Mode to automatically control picture brightness

Equipped with an automatic Eco Mode to automatically control picture brightness

Eco Mode reduces light intensity automatically and imperceptibly when switching from white screens like charts or bright images to a dark screen or image. This function can reduce the power consumption by up to 24%. Both the projector and its remote are equipped with an Eco button for easy setting of Eco Mode.

Lengthen lamp lifetime

Replacement lamp

Using Eco Mode can increase the lamp lifetime to 5000 hours*.Furthermore, the low-energy design keeps power consumption to 0.2W(100-130V AC)/ 0.4W(200-240V AC)during standby (Power-saving Mode), which helps reduce total cost of ownership.
*For P350X. This is not a guaranteed value.

The Carbon Meter lets you visually check the amount CO2 you reduced

Equipped with an abundance of handy functionality.

Built-in monaural speaker with a powerful 10 W output

Computer-free presentations

The projector allows you to project images without a computer. Simply insert a USB memory device loaded with image data directly into the projector. In addition to still images in JPG, BMP, and PNG formats and video files in MPG and WMV formats, PowerPoint* and Adobe® PDF* files can also be displayed without a computer.

  • *Limited to specific fonts, etc.

Basic DICOM mode allows simple display of medical images

Basic DICOM mode allows simple display of medical images

The projector is preset with gradation characteristics for medical images (similar to DICOM standards). You can display medical images stored as DICOM files for presentations at academic conferences, etc.

  • *Cannot be used for the display of images for medical diagnosis.

The Quick start function starts projection a mere 3 seconds after the power is switched on

Quick Cooling and Direct Power Off allow speedy clean-up and transfer after use

Designed for a low noise level of 29dB* (in Eco Mode) that doesn't disturb conferences or lessons

The RPM of the fan has been reduced and operation noises have been suppressed for a substantial reduction in noise.

  • *For P350X.

The security function uses password settings and key locks to prevent unauthorized use
