The BenQ LW820ST is a BlueCore laser education projector that combines ultra-short-throw projection, high brightness, and interactive capabilities to deliver engaging, immersive learning experiences in classrooms of all sizes.
With 3,600 ANSI lumens, a dual color wheel system, and a 0.49 short-throw ratio, the LW820ST produces crisp, vibrant images up to 100 inches while eliminating shadows and glare. Its fully sealed laser engine and Dust Guard™ technology ensure 20,000 hours of maintenance-free operation, resisting brightness and color decay over time. PointWrite™ multi-touch functionality allows students and teachers to interact directly on any flat surface, with multi-user support, gestures, and multi-screen drawing for collaborative learning.
Superior Dustproofing & Sealed Laser Engine
Dust Guard™ technology hermetically seals the laser modules and engine, protecting critical components and prolonging the projector’s lifespan while maintaining high brightness performance.
Brilliant Image Quality & High Brightness
BlueCore laser projection with dual color wheels increases RGBY purity and saturation, delivering clear, vivid images. Custom Brightness allows precise control of light output in 1% increments for energy efficiency and perfect edge blending in multi-projector setups.
Laser-Enabled Ultra-High Contrast
Native contrast ratio of 100,000:1 produces deep blacks, vivid colors, and fine details. Spontaneous response ensures instant on/off and true black blanking for flexible performance.
Instant Power-On
The LW820ST powers on and off instantly, reducing setup time compared to lamp-based projectors and enabling quick transitions during lessons.
