1080p (1920x1080) is a set of HDTV high-definition video modes. With the superb clarity of available 1080p Full HD, you'll enjoy exceptional details no matter on Blu-ray movies, video games or business presentation. 4,000 lumens high brightness provides the ability to project crystal clear, vibrant images from a long distance on a large screen even in daytime indoors. The contrast ratio is up to a whopping 20,000:1. DynamicBlack improves image contrast by analyzing onscreen content frame-by-frame and then dynamically adjusting lamp power to optimize black levels. The black can be extremely black and white is brilliant white. Project in either light or dark environments with Acer LumiSense+ which adjusts the image based on available light. Equipped with an intelligent ambient light sensor, projector can optimize image brightness and colour saturation based on ambient lighting conditions. What's even better, content-aware process also analyzes projected contents frame by frame and dynamically adjusts image visibility to the optimum level. Acer ColorBoost3D presents true-to-life colours through an optimized 6-segment colour-wheel design, advanced lamp illumination technology, and powerful TI image processing. It can reduce brightness decay and colour shift while displaying 2D and 3D content through enhancing colour brightness, while also compensating colour saturation and colour temperature. ColorSafe II technology combines the dynamic RGB control techniques, and advanced projector lamps to extend projector lifespan. The technology prevents yellow hues, the sign of colour decay, so even after thousands of hours of usage, projector continues to deliver consistent, natural colours. Acer Bluelight shield allows users to lower levels of blue light to lessen the negative effects of blue light exposure. There are three levels of filter which suitable for different scenario.
