BenQ LH890UST 4000 ANSI Lumens 1080P Education Projection comes with IP5X Dustproof Mechanism, BlueCore Laser Technology or superb image quality, Lens Control: Manual Focus, 2D keystone and Fixed Zoom Ratio. Here, Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens. This Projection has Dual synchronized BlueCore color wheels, that utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance. The Hermetically Sealed DLP Chip, Comprising over two million micromirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation. This latest BenQ LH890UST Projection, designed with DustGuard technology including sealed laser modules to protect the laser bank. This lock-and-key design hermetically seals the laser engine from dust* to prolong Projection lifespan. Here, Anti-Dust Accumulation Sensor Resists Dust Buildup and also 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. In this Projection, the BlueCore 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 Projection to deliver superior viewing experiences, Laser-Enabled Ultra-High Contrast, Long Lasting High Brightness and give you 20,000 Hour Long-Lasting Performance. This Projection is comptible with Advnced Interactive Module, Control System Compatibility (Crestron, AMX, PJ Link, and Extron IP Link for network control via LAN,) and Multiple Choices for Wireless Compatibility. The latest BenQ LH890UST 4000 ANSI Lumens 1080P Education Projection has 3 years Parts & Service warranty and Lamp.
