Power Saving, Eco Friendly

Power Saving, Eco FriendlySaving More on Power Consumption with BenQ's SmartEco™ Technology

Offering lower Total Cost of Ownership (TCO) and optimized projection through dynamic power saving, uncompromised brightness, exquisite picture quality and optimized lamp life – SmartEco technology has perfected what a DLP projector can do. With this innovation, schools and companies are able to save up to 70% of lamp power consumption and lower maintenance costs through dynamic power saving features while bringing an ultra-vivid viewing experience to every presentation.

SmartEco Mode: Power Smarter

By detecting the input content to determine the amount of brightness required for optimum color and contrast performance, the SmartEco Mode is able to reduce lamp power while delivering the finest image quality. No compromise!

SmartEco Mode: Power Smarter
*SmartEco Mode, the dynamic power saving mode,can save at least 70% power based on the projection content level.

Eco Blank Mode

The Eco Blank Mode, which lowers power consumption down to 30%, can be used to blank the projection screen when the projector is not in use, eliminating distractions in class and redirecting students' focus back on the teacher.

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, prevents the projector from running at full lighting power. It's just another way of doing your part in saving the planet.

Good Things Come in Short Distances

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 perfect place for educational use.

Non Short-throw

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, greatly decreasing shadow disruptions. Teachers can enjoy teaching without worrying about the class being interrupted.

Zero Eye-Blinding Lights

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 short throw technology keeps light out of the way.

BenQ DLP® Projectors
Long-Lasting Image Perfection with DLP Technology

Timeless Image Quality

BenQ's DLP Colorific 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.

DLP technology also affords a filter-free engine design ensuring 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, 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 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.

Razor-Sharp Clarity with Ultra-Readability

Vibrant, True-to-Life Colors

Even in lit venues, BenQ DLP Colorific Projectors achieve the optimal balance of brightness and color accuracy, with BrilliantColor™ technology additionally boosting true-to-life colors that captivate. BrilliantColor enables up to six-color processing by incorporating the secondary colors Yellow, Cyan, and Magenta along with primary Red, Blue, and Green. From intense hues to elusive mid-tones like aqua blues and light yellows, your presentations are rendered in pure, living splendor.
