BenQ LH850ST 1080p Laser Installation Projector - 4000 Lumens
Effortless Blending for an Interactive, Immersive Experience
The BenQ LH850ST laser projector is a simulation projector featuring user-friendly colour calibration technology to effectively reproduce dynamic images for a sleek, immersive experience during multi-projector scenarios.
Simulation Mode for Lifelike, Immersive Visuals
4,000 ANSI Lumen Brightness with a Simulation Mode for Enhanced Visual Precision
Equipped with 4,000 ANSI lumens of high brightness and a dedicated Simulation Mode, LH850ST elevates colour intensity and visual clarity. Its Simulation Mode specifically enhances greens, yellows, and reds, bringing your content to life with vivid realism.
Dual Colour Wheels Reproduce Colours Accurately
The LH850ST laser projector utilises DLP technology with a dual colour wheel system. The two synchronised colour wheels feature an additional yellow segment, producing a precise RGBY spectrum for optimal chromatic performance.
DLP Technology for Long Lasting Vibrant Colour
BenQ’s LH850ST laser projector adopts Academy Award-Winning DLP projection technology, providing stable and long-lasting accurate colours. With a durable DMD chip that lasts over 200,000 hours, it ensures vivid colours and true whites without yellowing over time. Designed for 24/7 operation, it offers instant power-on for meetings, eliminating the need for a warm-up period, while also saving time and money on lamp replacements.
Vivid Clarity in Bright Ambient Environments
LH850ST’s 4000 ANSI Lumens high brightness and 1080p high resolution produce high quality images under bright ambient lighting. And its 3,000,000:1 native high contrast reproduces true blacks, vivid colours, and exquisite details.
IP5X Dust Guard™ Dustproofing for Severe Conditions
LH850ST utilises sealed laser modules and enclosed light engines to protect the DMD chip, colour wheel sensor, laser package, and other optical components. This lock-and-key design hermetically seals the engine from dust to prolong projector lifespan. The technology has also passed the dust chamber test standard for the international dustproof rating of IP5X.
Optimal Installation Flexibility
LH850ST has high installation flexibility and T/R 0.5 short throw design that are best for small-room multi-projector display.

White Balance Calibration for Seamless Edge Blending
BenQ LH850ST with exclusive white balance adjustments reduce variables between images projected from different projectors that the most people cannot see any difference. This allows for seamless and accurate picture quality without disruptive discrepancies, saving the installation staff from repetitious fine-tuning.
Short-Throw Design Shatters Space Constraints
A LH850ST short-throw laser projector is best for indoor interactive entertainment, training simulation, and commercial space exhibitions. It’s easy to project images larger than 100” within 1.07m and short-distance projection prevents people or objects from getting in the way and casting a shadow on the projected image for the most immersive viewing experience possible.
Digital Shrink and Shift for Accurate Image Adjustment
After the projector is installed, LH850ST allows installation staff to adjust the projected image by reducing and moving it by 0.5% to where you want accurately.
Corner Fit for Precise Image Adjustment
LH850ST’s digital trapezoid correction function allows users to correct images easily. Use the remote control to correct the images in a few clicks. Furthermore, the Corner Fit feature also allows users to fine-tune to the final image.Seamless Alignment and Sharp Focus From Any Angle
Achieve flawless visuals and crisp images with the push of a button. The Large 2D Keystone correction ensures quick alignment, while Quick Focus delivers clear and precise visual from any projection angle.
Large 2D Keystone Correction
Easily adjust and align images with just a few clicks of the remote control for a convenient and seamless setup.
Quick Focus
Press the Focus button on the remote control as well as make slight adjustments to deliver sharp images.Wireless Scalability for Enhanced Flexibility

Wireless Casting from Smart Devices
To meet the growing BYOD trend, BenQ’s optional Wi-Fi dongle lets meeting participants project Full HD multimedia content wirelessly from any mobile device. This wireless technology supports up to four presenters via a four-way split screen, enhancing collaboration and creating an immersive experience in dynamic settings for all participants.Durable and Secure Design Suitable for Any Environment

An Enhanced Security Bar for Secure Installation
With a 40% wider security bar, the LH850ST offers improved stability and ease of installation, allowing users to securely set up the projector with confidence.Easy-to-Maintain
Centralised Remote Management
Multiple Control System Compatibility
