BenQ leads the way with future-proof interactive projectors, featuring innovative BlueCore laser technology and superior dust-proofing design for superb picture quality and maintenance-free operation. Maximizing education investment and collaborative learning with short throw projection, BenQ LW820ST utilizes the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, energy efficiency and environmentally friendly choice for the leading school.
BenQ BlueCore laser technology for pure color
Powerful BlueCore laser projectors employ dual color wheel systems to unleash outstanding color performance by increasing color ratios and purity of RGBY color, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.
Superior dust-proofing design to prolong projector lifespan
BenQ LW820ST is designed with Dust Guard technology including sealed laser modules to protect the laser bank. This lock-and-key design hermetically seals the laser engine from dust to prolong projector lifespan.
Anti-dust accumulation sensor resists dust build-up
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LW820ST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colors, or even shutdown.
Long-lasting high brightness
LW820ST produces 3,600 lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms with lights kept on during lessons. LW820ST's Custom Brightness function also allows manual light output adjustments in 1% increments to precisely control projection brightness to fit ambient lighting and conserve energy, as well as providing perfect edge blending for multiple projector applications.
Laser-enabled ultra-high contrast
LW820ST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colors, and fine subtle details. LW820ST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
Long-lasting performance
With a fully sealed laser light source and an innovative sealed laser engine design, BenQ BlueCore laser education projectors guarantee durable maintenance-free operation, preventing extra expenses on lamp replacement and maintenance. The laser light source resists color and brightness decay over time, offering significantly more reliable performance after a period of operation.
Unmatched readability
With amazing high contrast, BenQ education projectors utilize advanced DLP-optimized optical lens systems to provide precise readability and crisp resolution for every single sub-pixel.
