    LX820ST Projector

    BlueCore Laser Projector with Short Throw XGA LX820ST

    Uninterrupted Learning Through Long-Lasting Projection

    The World’s No.1 DLP brand BenQ leads the way with futureproof interactive projectors featuring innovative BlueCoreTM laser technology and superior dustproofing design for superb picture quality and maintenance-free operation. Maximizing education investment and collaborative learning with short throw projection BenQ LX820ST / LW820ST utilize 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 BlueCoreTM Laser Technology 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 Bright

    Precision-Aligned High-Output Laser Source

    Zero-deviation alignment of BlueCore laser diodes boost luminous flux into the light tunnel improving light efficacy to 3600 lumens.

    Superior Performance

    Secondary Yellow-Infused Color Wheel

    Dual synchronized BlueCore color wheels utilize an additive yellow segment stimulating precise RGBY spectra for optimal chromatic performance.

    Superior Durability

    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 100000 hours without degradation.

    Superior Dustproofing Design to Prolong Projector Lifespan

    BenQ LX820ST is designed with Dust GuardTM 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.

    *Dust chamber test standard: JIS Class IP5X

    Sealed Engine for Laser Light Source

    With a fully enclosed laser light source and an innovative sealed engine design powered by BenQ Dust GuardTM technology BlueCore education projectors guarantee 20000 hours of maintenance-free operation to prevent extra expenses on lamp replacement and maintenance. The laser light source resists brightness decay making BenQ laser education projectors highly stable while ensuring high brightness performance through years of usage.

    Anti-Dust Accumulation Sensor Resists Dust Buildup

    Incorporating color wheel sensors with an ingenious anti-dust accumulation feature LX820ST 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

    LX820ST’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.

    Long Lasting High Brightness

    LX820ST produces 3600 ANSI 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. LX820ST’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

    LX820ST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100000:1 for true deep blacks vividly rich colors and fine subtle details. LX820ST also features spontaneous response requiring no wait to turn on or resume from blanking in true black for flexible performance capability.

    Instant Power-On

    BenQ BlueCoreTM education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.

    20000 Hour Long-Lasting Performance

    With a fully sealed laser light source and an innovative sealed laser engine design BenQ BlueCoreTM laser education projectors deliver 20000 hours of 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.

    Unobstructed Instruction Without Space Constraints

    Offering a big screen in short distances with a 0.63 short-throw ratio LX820ST eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.

    Bigger Images

    BenQ education projectors offer a range of resolutions and projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 100 inches BlueCore short throw education projectors deliver increased classroom versatility at reduced costs.

    Create Interaction on Any Surface

    PointWrite™ technology works on any flat surface so no expensive digital whiteboard or additional equipment is necessary. With the PointWrite™ module images can be projected onto a wall for multiple students to easily share and write on the same screen creating vast new opportunities for classroom interactivity and enabling possibilities for modern digital classrooms.

    Multi-Touch with Pens and Multi-Screen Drawing

    PointWrite™ projectors offer multi-user capability and two PointWrite™ projectors can be used to double the projection surface. With QWrite* Whiteboard Mode teachers can run different applications or display view and annotate across two monitors.

    * BenQ exclusive annotation software QWrite™ is compatible with BenQ PointWrite™ module.
