Superior Lighting with LED Light Source
LED lighting lets you enjoy a wider color gamut and greater bulb durability than traditional lamps. Your ideas will pop with the brightness of LED technology, creating vibrant visuals and delivering consistent color saturation. In addition, by eliminating the potential pollution from mercury lamp disposal, your projector is free from environmentally hazardous substances.

Expressive Levels of Dynamic Black Contrast
The contrast ratio is up to a whopping 100,000:1. 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.

Acer LumiSense+ Ambient Light Detection
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 color 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.

Give Color a Boost with ColorBoost3D
Acer ColorBoost3D presents true-to-life colors through an optimized 6-segment color-wheel design, advanced lamp illumination technology, and powerful TI image processing. It can reduce brightness decay and color shift while displaying 2D and 3D content through enhancing color brightness, while also compensating color saturation and color temperature.

Immune to Color Decay with Acer ColorSafe II
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 color decay, so even after thousands of hours of usage, projector continues to deliver consistent, natural colors.
