Superior Dustproofing Design to Prolong Projector Lifespan
BenQ LH890UST is designed with DustGuardTM 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 Buildup
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LH890UST 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.
Brilliant Display of Lecture Content
LH890UST’s powerful BlueCoreTM laser projection utilizes a dual color wheel system to produce outstanding color performance by increasing color ratios and purity of RGBY colors, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.
Laser-Enabled Ultra-High Contrast
LH890UST 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.
LH890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
