BenQ LW720 4000-Lumen WXGA Laser DLP Projector

Project high-resolution images and presentations in nearly any environment with the BenQ LW720 4000-Lumen WXGA Laser DLP Projector. Its 4000 lumens of brightness overcomes ambient light in many situations, while its dynamic contrast ratio helps keep images and text clear and distinct. Its 1.45 to 2.24:1 throw ratio and 1.5x zoom provide a range of installation options.

The LW720 has composite video, S-Video, two VGA, and two HDMI inputs to support both analog and digital video sources. Its VGA output allows you to daisy-chain multiple projectors or displays to show the same video source, and the 1/8" audio output to connect external speakers. It is controllable via Ethernet or RS-232 and includes a remote control.

BlueCore Laser Technology

Enhanced Brightness

The virtually zero-deviation alignment of the BlueCore laser diodes helps boost luminous flux into the light tunnel to produce up to 4000 lumens of brightness.

Secondary Yellow-Infused Color Wheel

Dual synchronized BlueCore color wheels use an additive yellow segment, simulating the RGBY spectrum for augmented chromatic performance that achieves up to 90% of Rec.709 color coverage.

Hermetically Sealed DLP Chip

The DLP chip is hermetically sealed to resist heat to help it provide up to 100,000 hours of life without degradation.

Infographic Mode for Enhanced Presentation Quality

Infographic mode is designed to showcase text and graphics in detail, and Vivid Mode helps provide augmented color performance during video or image presentations

LumiExpert Ambient Light Detector for Eye Comfort

The 4000-lumen brightness level of the LW720 allows presentations to be viewable in comfortably lit medium-sized conference rooms supporting 20 to 40 people. LumiExpert technology is engineered to automatically detect the ambient light conditions of a meeting room and adjust the projector's brightness to enhance clarity and comfort.

Instant On/Off and Signal Power On

The laser light source allows for spontaneous response, requiring no wait to turn on or resume from image blanking. Additionally, the signal power on feature turns the projector on automatically once a signal is detected over VGA or HDMI.

Engineered for Enhanced Reliability

DLP Technology

The BlueCore line of projectors use a single-chip DLP designed to produce true-to-life colors and legible text with virtually no blurring, shadowing, or interference patterns. The DLP chip can last up to 100,000 hours without degradation.

Constant Brightness Mode

The LW720 is designed to deliver up to 80% of brightness with clear image quality for its lifetime.

Dustproofing for Severe Conditions

The LW720 is designed with sealed laser modules and enclosed light engines to help protect the DMD chip, color wheel sensor, laser light source, and other optical components. The design has passed the JIS Class IP5X dust chamber test standard.

Installation Flexibility

Zoom and Lens Shift

The horizontal and vertical lens shift options, as well as 1.5z zoom, help you align images in nearly any challenging venue, such as when lights or vents are located in the mounting area. Lens shift enables you to move the image up or down, while the zoom offers a wider range of throw distances for installation flexibility in various scenarios.

Image Calibration for Projection Alignment

The LW720 is equipped with a two-dimensional keystone correction range of ±30° to counteract the trapezoid effect, which occurs when a projector is installed off-center. You can also use Corner Fit to adjust each corner independently to achieve your desired image geometry.

QCast Mirror-Compatible

To satisfy BYOD needs, the optional QCast Mirror HDMI wireless adapter lets meeting participants share Full HD content wirelessly from any compatible mobile device or laptop. The LW720 has a hidden slot for the adapter.

Compatible with the InstaShow WDC10 for Wireless Presentations

The separately available InstaShow WDC10 is a zero-software solution that allows up to 16 presenters to connect from any compatible device. InstaShow requires no driver installation and is compatible with virtually any OS or hardware platform, making it easy for presenters to wirelessly take turns delivering presentations. The LW720 has a designated space for the InstaShow module for a streamlined appearance.

Integrated Network Control and Management System Compatibility

Designed for Comprehensive Control System Compatibility

The LW720 is compatible with a number of projector control systems, including Crestron, AMX, and PJ-Link for network control via LAN, making it simple to integrate into corporate network infrastructures. When there is no LAN infrastructure, the LW720 also supports RS-232 for reliable long-distance installations up to 49'.

Centralized Control with BenQ MDA Software

BenQ Multiple Display Administrator (MDA) software provides centralized multiple-projector management, including automated opening and closing procedures for public spaces, remotely controlled power on and off, and scheduling for institutions and corporations. Also, up to 253 projectors on the same LAN can be updated at once within one interface.
