V311W / V281W / V311X

Functions and Features

WXGA models available

Two WXGA models (V311W/V281W) with a resolution of 1280 x 800 are available to support aspect ratios of the more and more popular widescreen computers.

High brightness 3100 lumens (V311W/V311X)

High contrast ratio 3000:1

Built-in 7 W speaker for integrated audio solutions

Equipped with an HDMI input port

This series is equipped with an HDMI port, which enables them to project digital image signals in high resolution. The HDMI input also supports audio signals.

Quick power off & Direct power off

The Quick Power Off function stops the cooling fan immediately after turning off the power to the projector, which makes it possible to remove the projector quickly. For a rapid shut down, the projector can be turned off without powering off the projector using the Direct Power Off function and a power strip equipped with a switch and breaker.

Project 3D images with a single projector

Project 3D content* from various sources with a single projector. The V311W and V311X are certified as a display device for NVIDIA® 3D Vision.

  • *Commercially available DLP Link compatible LCD shutter eyeglasses are required.

Carbon meter for visualizing ecology

Carbon meter

The projector employs the Carbon Meter indicating the reduced amount of CO₂ emissions in Eco Mode. Visually confirm the numerical value indicating the reduction in CO₂ emissions in comparison with Eco Mode Off operation.

Low power consumption in power-saving mode

Power consumption in power-saving mode is 0.4 W (100-130 V AC) / 0.5 W (200-240 V AC). These enhancements help to reduce the TCO (total cost of ownership).

Crestron RoomView

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

Security bar and password protection functions

Security bar

By using passwords, the projector cannot be used by unauthorized persons. Furthermore, since the main unit has a security chain opening, unauthorized removal of the projector is prevented by inserting the security cable or wire commercially available into the opening.
