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 2000 hours of intense usage inserting a new bulb produces image quality comparable to a brand-new projector.
