BenQ MW809ST interactive WXGA short throw education projector with 3000 ANSI Lumens, offer flexibility and image quality to enrich your teaching. Incorporating colour wheel sensors with an ingenious anti-dust accumulation feature, MW809ST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colours, or even shutdown. Offering a big screen in short distance with a 0.49 short-throw ratio, MW809ST eliminates distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board. MW809ST produces 3,000 high ANSI lumen brightness and resolution for perfect projection performance with crisp images and sharp text even in bright lecture room. High brightness provides clear content under high ambient lighting, allowing lights to be kept on during classes for note taking and interactive collaboration. BenQ education projectors offer a range of resolutions and projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 120 inches, our ultra-short throw education projectors deliver increased classroom versatility at reduced costs. With sealed design that protects the DLP chip from dust-induced image degradation and the industrial-grade durability of DLP projection technology, BenQ education projectors are capable of maintaining long-lasting picture quality by eliminating colour decay. Unlike non-DLP projectors, BenQ education projectors deliver premium picture quality equivalent to the result from brand new projectors after lamp replacement. BenQ DLP projectors feature class-leading high fill factor, minimizing black borders around each pixel to eliminate the dreaded 'screen door effect' commonly observed in non-DLP projectors. BenQ education projectors produce superior definition and clarity in small-size text and fine details for beautifully rendered images instead of pixelated graphics. Ideal for text, numbers, and tables widely used in instruction, BenQ education projectors leverage the native DLP advantage of digitally controlled micromirrors on the DMD chip. By completely toggling off reflective micromirrors to generate deep true blacks, BenQ education projectors create high native contrast ratio for sharp readability and crisp resolution at every single sub-pixel. PointWrite technology transforms BenQ education projectors into collaborative platforms that turn any surface into an interactive whiteboard. Seamless integration of PointWrite kit and QWrite software with BenQ projectors encourages a truly collaborative learning environment where students and teachers work together using intuitive templates along with annotation tools.
