## Description

From the manufacturer Saving More on Power Consumption with BenQ's SmartEco Technology Efficiency Installation with BenQ Wall Mount Alignment Designed to help ensure a fail-proof projector installation, BenQ has implemented extra help into its wall mount design. this installer-friendly ultra short-throw projector wall mount features an installation chart and a measuring ruler to help you find the most suitable projector screen alignment and image position for your classroom. Offering lower TCO and optimised projection through dynamic power saving, uncompromised brightness, exquisite picture quality and optimised lamp life- SmartEco technology has enhanced what a DLP projector can do. With this innovation, schools and corporates are able to save up to 70 per cent of lamp power consumption and lower maintenance through dynamic power saving features while bringing an ultra-vivid viewing experience into every presentation. SmartEco Mode: Power Smarter By detecting the input content to determine the amount of brightness required for optimum colour and contrast performance, the SmartEco Mode is able to reduce lamp power while delivering the fine image quality. No compromise. Eco Blank Mode The Eco Blank, which lowers power consumption up to 70 per cent, can be used to blank the projection screen when the projector is not in use, in turn eliminating distractions in class and redirecting students' focuses back on the teacher. No Source Detected Mode The No Source Detected mode, which can be set to enter the Eco Blank mode after three minutes of inactivity or to the Auto Power Off mode after no display source has been detected for over 30 minutes, can keep the projector from running with full lighting power. Zero Space Constraints You don't need a big room or a lot of free ceiling space to create a big picture when you've got an ultra short-throw projector. Teachers can think outside the box to turn every corner into the ideal place for educational use. Zero Shadow Disruptions An ultra short-throw projector can be placed close to the screen in front of the class and well out of students' way, decreasing the occurrences of shadow disruptions. Teachers can enjoy teaching without worrying about the class being interrupted. Zero Eye-Blinding Light An ultra short-throw projector keeps the projector light from shining directly into everyone's eyes. The intensity of the projector beam may be potentially harmful. So it's ideal to keep it out of the way. Blu-Ray Full HD 3D Supported BenQ MX842UST is built with DLP technology to support 3D functionality, allowing schools to bring an immersive learning experience to their students with a simple preparation of 3D glasses and 3D content. Long-Lasting Image with DLP Technology BenQ DLP projectors are built with enduring enjoyment in mind, ensuring razor-sharp clarity, ultra-readability and true-to-life colour for years to come. BenQ uses DLP technology to reflect pure light from millions of micro mirrors on a DMD chip through the colour wheels. Since the mirrors are colourless and protected within a nearly-sealed engine, BenQ DLP projectors have no ageing 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. DLP technology also affords a filter-free engine design for carefree confidence in long-lasting image quality. BenQ's SmartEco technology further boosts contrast performance and image quality endurance while saving up to 70 per cent on lamp power consumption. Razor-Sharp Clarity with Ultra Readability Vibrant, True-to-Life Colours The MX842UST achieves the optimal balance of brightness and colour accuracy, with BrilliantColor Technology additionally boosting true-to-life colours that captivate. Enabling a 96 per cent fill factor, DLP technology supplies pixel circuitry behind the pixel, thereby eliminating the thick dark bezels around individual pixels, which diminish colour and detail. A higher fill factor and less black border translate to noticeably purer, more intense colour and smoother image quality. BenQ 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.
