ViewSonic’s LS850WU is an advanced 5,000 ANSI Lumens WUXGA installation projector. Adopting 2nd generation laser phosphor technology, it offers high and consistent brightness for a reliable light source life of 20,000 hours.

High Brightness
Packed with 5,000 ANSI Lumens, it is guaranteed to produce high levels of brightness suitable for large spaces with a lot of ambient light.

Ultra-high Contrast Ratio
Boasting a 3,000,000:1 ultra-high contrast ratio, even the finest shades of colour are enhanced – a key characteristic for delivering razor-sharp images.

2nd Generation Laser Phosphor Technology
The ViewSonic new laser projector adopts the 2nd generation laser phosphor technology. In addition to inheriting excellent colour performance, lamp-free design, and instant on/off switch from the previous generation, technology on the new generation improves around 20% of brightness, better heat-resistance, and a smaller module design, making the images consistent in ambient settings as well as increased reliability with a more compact size for extended use in various scenarios.

Long-lasting Lifespan
Laser technology offers a lifespan of up to 20,000 hours (4 hours per day for more than 13 years), delivering reliable long-term performance with no degradation in brightness over time so that your installations are consistently vibrant.

Adaptable to any environment
Equipped with a 1.6x optical zoom lens, the projector provides mounting flexibility with a wider throw distance range.

Installation Flexibility
The tool-free, lens shift control knobs make adjusting the projection lens up, down, left, and right easy. It provides flexible installation options with a wide adjustable range (H: +/- 23%, V: +/-50%) and less placement restrictions.

360° Creative Applications
The projector can freely rotate at any angle vertically to help with creative applications, allowing projection onto ceilings, walls, or angled signage.

90° Portrait Mode
Portrait mode allows users to turn the projector 90 degrees to increase the vertical field of view and add more applications for projection mapping, staging, and advertising.

Lighter Weight and Compact Size
It is almost half the weight and 35% smaller in size compared to its predecessor, which reduces the cost of transportation and enhances the ease of installation.

Built-in HDBaseT Receiver
Its built-in HDBaseT receiver is a cost-effective solution to transmit uncompressed high resolution audio and video at a lengthy distance (100 meters for 1080p) when combined with a Cat.5e/6 cable and is compatible with any certified HDBaseT transmitter.

Non-stop 24/7 Operation
With an advanced cooling design, it enables 24/7 operation without degradation of quality or performance, making the projector ideal for applications that require continuous projection.

A Simpler Way to Update Projector Software
ViewSonic Projector Software Update is available online and gives you the ability to keep your projector firmware up to date easily and conveniently; no need to take your projector in to a service centre for software updates.

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.

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

Sealed Optical Engine with IP5X
The advanced 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.

Reduced Energy Consumption
When no signal has been detected, the projector will automatically power off to conserve energy and therefore prolongs its lifespan.

Energy Efficiency
Power Saving Mode allows users to extend the projector’s lifespan and minimise energy consumption. When in Power Saving Mode, the projector will automatically switch into Eco Mode and SuperEco Mode whenever there is no signal input detected.
