A total classroom interactive solution, the MW853UST offers superior connectivity with ultra short-throw design, and optional PointWrite interactivity. The 10,000:1 ultra-sharp contrast ratio, 3,200 ANSI lumen brightness and lamp life are enhanced by the SmartEco technology for long lasting, reliable and vibrant images. BenQ DLP Projectors are built with enduring enjoyment in mind, ensuring razor-sharp clarity, ultra-readability and true-to-life color for years to come. We use leading-edge DLP Technology to reflect pure light from millions of micro mirrors on a DMD chip through our advanced color wheels. Since the mirrors are colorless and protected within a nearly-sealed engine, BenQ DLP Projectors have no aging problems and are virtually immune to image decay, consistently delivering picture excellence time and time again. In fact, after 2,000 hours of intense usage, inserting a new bulb produces image quality comparable to a brand-new projector. BenQ MW853UST is built with latest DLPR technology to support 3D functionlity, allowing schools to bring an immersive learning experience to their students with a simple preparation of 3D glasses and 3D content.
