High Native ANSI Contrast Ratio
Native contrast, otherwise known as ANSI contrast, is what drives the perceived quality of an image. As demonstrated in the patterns below, ANSI (American National Standards Institute) measures and compares the brightness of black and white segments, offering a more accurate representation of a projector's contrast performance besides FOFO (Full On/Full Off), which measures and compares the brightness of full black and full white screens. Since the reality is that most of the images projected are not strictly 100% black and white but a mixed of black and white segments. With a high 560:1 ANSI contrast ratio, the HT1085ST is built to reveal the subtlest details in the deepest, truest blacks.

BenQ DLP® Projectors︱ Long-Lasting Image Perfection with DLP Technology
Timeless Image Quality:
BenQ Colorific 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 Colorific 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 DLP Projector
DLP Technology also affords a filter-free engine design for carefree confidence in long-lasting image quality and reduced total cost of ownership. BenQ's SmartEco™ Technology further boosts contrast performance and image quality endurance while saving up to 70% on lamp power consumption.
Razor-Sharp Clarity with Ultra-Readability:
Enabling a 96% fill factor, DLP Technology supplies pixel circuitry behind the pixel, thereby eliminating the thick dark bezels around individual pixels, which diminish color and detail. A higher fill factor and less black border translate to noticeably purer, more intense color and smoother image quality.
BenQ Colorific DLP Projectors also feature high contrast ratios for flawless rendering of small text, fine lines, and dark scene details. Blacks are deeper and overall image quality is more focused and clean. Your presentations will be easily readable and highly effective, even from the back row of a well-lit venue.
