Uncompromised high brightness MW826STH produces 3, 500 high ANSI lumen brightness & resolution for perfect projection performance with crisp images & sharp text even in bright lecture room. High brightness provides clear content under high ambient lighting, allowing lights to be kept on during classes for note taking & interactive collaboration. Crisp readability via high contrast ratio Ideal for text, numbers, and tables widely used in instruction, Ben Q education projectors leverage the native DLP advantage of digitally controlled micromirrors on the DMD chip. By completely toggling off reflective micromirrors to generate deep true blacks, Ben Q education projectors create high native contrast ratio for sharp readability & crisp resolution at every single sub-pixel. Enduring picture perfection from DLP technology With sealed design that protects the DLP chip from dust-induced image degradation & the industrial-grade durability of DLP projection technology, Ben Q education projectors are capable of maintaining long-lasting picture quality by eliminating color decay. Unlike non-DLP projectors, Ben Q education projectors deliver premium picture quality equivalent to the result from brand new projectors after lamp replacement. High DLP pixel fill factor for superb viewing experience Ben Q DLP projectors feature class-leading high fill factor, minimizing black borders around each pixel to eliminate the dreaded "screen door effect"commonly observed in non-DLP projectors. Ben Q education projectors produce superior definition & clarity in small-size text & fine details for beautifully rendered images instead of pixelated graphics. Bigger images Ben Q education projectors offer a range of resolutions & projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 120 inches, the ultra-short throw education projectors deliver increased classroom versatility at reduced costs. Interaction on any surface Point Write technology transforms Ben Q education projectors into collaborative platforms that turn any surface into an interactive whiteboard. Seamless integration of Point Write kit & QWrite software with Ben Q projectors encourages a truly collaborative learning environment where students & teachers work together using intuitive templates along with annotation tools. Multi-touch &multi-screen drawing With enhanced multi-touch capability for pens or fingers, two Point Write projectors can be used in conjunction to double the interactive projection surface, creating vast new opportunities for interactive learning in modern digital classrooms. In QWrite Whiteboard Mode, teachers can also run different applications or display, view, and annotate across two surfaces. Intuitive setup Reliably accurate in any ambient lighting, Point Write auto calibrates & saves its settings immediately when plugged into a computer's USB (Universal Serial Bus) port, remaining ready with no manual configuration or complicated training for teachers. Windows gesture support Point Write projectors support intuitive Windows gestures such as zooming in & out or scrolling while browsing webpages, pictures or Google Maps. All multi-touch commands & gestures are supported for Windows 8 or above & future applications.
