The ViewSonic LS831WU has revolutionized short-throw projectors. With 4500 Lumens combined with WUXG resolution, this projector delivers a very bright high-quality image that can be used in cassroom setting or retail stores for signage. With a 0.25 throw ratio, users can easily get 100” image from less than 1 foot away from the screen. Screen size can further be expanded to up to 150" at a lower cost-per-inch compared to commercial flat panel displays. The ViewSonic LS831WU Adopting the 2nd generation laser phosphor technology offers consistent high brightness for a reliable 20,000 hours lifespan. Built-in HDBaseT receiver and 360° projection capability together ensure the ease of use desired. The embedded 20W cube speakers offer powerful audio right out of the box with three fine-tuned audio modes suitable for different application scenarios.









Maximum Space Saving


The 0.25 ultra-short throw lens allows for projecting a 100” image from only 21 cm away. Save your space!

0.25 Ultra-short Throw










Upgraded Performance


Thanks to 2nd generation Laser Phosphor technology, it improves brightness (by 20%), heat-resistance and reduces the product size in addition to excellent color performance, lamp-free design and instant on/off switch.

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.
