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 the occurrences of shadow disruptions. Teachers can enjoy teaching without worrying about the class being interrupted.

Non Short-throw

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 it's for the best to keep it out of the way.

BenQ Projectors ︱ Long-Lasting Image Perfection with DLP Technology

Digital Light Processing (DLP), awarded 2015 Academy Award of Merit (Oscar statuette), is the leading projection technology used in 90% of world’s digital cinemas and 100% of IMAX theaters. With DLP dominating the worldwide projector market with over 50% share, BenQ is today the #1 bestselling DLP projector brand, delivering unmatched world-class performance.

Timeless Image Quality: Colorific Technology Delivers Lifelike Color, Year After Year

You'll also experience dramatic contrasts for remarkable clarity, higher impact, and greater legibility. BenQ's Colorific projectors are dependable year after year.

HT1075 Timeless Image Quality

BenQ DLP Projector

HT1075 Timeless Image Quality

DLP Technology also includes a filter-free engine design for carefree confidence in long-lasting image quality and reduced TCO. 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 diminishes color and detail. A higher fill factor and less black border translate into 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 room.

Razor-Sharp Image Clarity

Vibrant, True-to-Life Colors

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

Vibrant True-to-Life Color
