      BenQ LH820ST laser DLP projector with low latency and user-friendly color calibration technology to effectively reproduce dynamic images for sleek immersion

      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.

      BenQ LH820ST’s Fast Mode offers latency as low as 16.67ms to ensure smooth dynamic images

      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.

      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.

      BenQ LH820ST’s 3600 ANSI Lumen high brightness and 1080p high resolution produce high-quality images under bright ambient lighting

      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.

      BenQ LH820ST has high installation flexibility and T/R 0.5 short throw design that are best for small-room multi-projector displays

      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.
