High brightness provides the ability to project crystal clear, vibrant images from a long distance on a large screen even in daytime indoors. Dynamic Black improves image contrast by analyzing onscreen content frame-by-frame & then dynamically adjusting lamp power to optimize black levels. The black can be extremely black & white is brilliant white. Project in either light or dark environments with Acer Lumi Sense+ which adjusts the image based on available light. Equipped with an intelligent ambient light sensor, projector can optimize image brightness & color saturation based on ambient lighting conditions. What's even better, content-aware process also analyzes projected contents frame by frame & dynamically adjusts image visibility to the optimum level. Acer Color Boost 3D presents true-to-life colors through an optimized 6-segment color-wheel design, advanced lamp illumination technology, & powerful TI image processing. It can reduce brightness decay & color shift while displaying 2D & 3D content through enhancing color brightness, while also compensating color saturation & color temperature. Color Safe II technology combines the dynamic RGB control techniques, & advanced projector lamps to extend projector lifespan. The technology prevents yellow hues, the sign of color decay, so even after thousands of hours of usage, projector continues to deliver consistent, natural colors. Image distortion sometimes happens when the projector is placed with improper distance or in a wrong position. Finding the right angle for your presentation will come easier with keystone correction which corrects vertical & horizontal distortions. Built-in speakers provide powerful sound, eliminating the need for external speakers. The audio ensures movies come to life, songs have more depth, & games are more engaging.
