Brighter, Smaller, Safer

Reliable Long-term Performance

The laser technology offers a maintenance-free lifespan up to 20,000 hours (4 hours per day for more than 13 years). And the cooling design enables 24/7 operation without degradation of quality or performance.

Bright Images for Public/Commercial Display

Packed with 4,500 ANSI Lumens and 3,000,000:1 contrast ratio, this projector can deliver bright and razor-sharp images in open spaces with high ambient light.

Larger Screen Size with Lower Cost-per-inch

Flexible installation and effortless transportation of the projector to show a 100’’ screen in comparison to 4-way split images on 4 commercial displays that requires more manpower and money.

Cost-effectively Receive AV Signal over Long Distance

With an integrated HDBT receiver, this projector can receive uncompressed HD video and audio over long distances (100 m for 1080p) via a Cat.5e/6 single network cable.

360° Creative Applications

The projector can freely rotate at any angle vertically to aid with creative applications, allowing projection onto ceilings, walls, or angled signage.

Easy Image Adjustment

Horizontal and Vertical Keystone correction along with 4 corner adjustment features eliminate crooked or distorted images for a perfectly proportioned picture every time.

Remote Control of Motorized Focus

Make your images sharp and clear effortlessly with the motorized focus triggered by commands on the remote control. Free from manual adjustment that requires approaching the ceiling-mounted projector and may disturb the original projection setting.

Centralized Control for Management Efficiency

This projector comes equipped with Control 4, Crestron, AMX, Extron and ViewSonic vController, an easy-to-use network management tool.

*The Control 4 driver will be built into the device in advance and get certification once it has finished the verification process.

A Simpler Way to Update Projector Software

ViewSonic Projector Software Update is available online and enables you to keep your projector firmware up to date easily and conveniently with your laptop and USB cable connection; no need to take your projector into a service center for software updates.

*The latest projector software update can be found in the download section at the bottom of the page when available.

Powerful Audio with 3 Modes

Three audio modes (speech, music, and movie) powered by 20W cube speakers and DSP chip to deliver the fine-tuned sound performance suitable for different scenarios.

SuperColor™ Accuracy

ViewSonic’s proprietary SuperColor™ Technology displays a wide color range, ensuring that users enjoy a true-to-life color performance in both bright and dark environments without sacrificing image quality.

Advanced Sealing with IP5X Certification

The sealed optical engine prevents dust and moisture from entering the projector and affecting the thermal system to ensure that the image quality and long lifespan are maintained.

Vivid and Immersive Display with BrilliantColorPanel™

Engineered with innovative panel technology, the ridged surface of optional BrilliantColorPanel™ is designed to deflect 90% of ambient light, and keeps the true color displayed on the screen unaffected. Meanwhile, it achieves a contrast ratio 4-times higher than that of an average projector screen and helps to eliminate washed-out images.
