The Acer H7850 are HDR-compatible (High Dynamic Range), reproducing a greater dynamic range of luminosity with expanded contrast and a wider range of brightness. The projectors adjust to brighter scenes so the highlights glimmer with detail, while in darker scenes, rich blacks are preserved and details typically hidden in the shadows are enhanced for greater overall luminance. Both projectors provide a DynamicBlack contrast ratio up to a whopping 1,000,000:1 thanks to frame-by-frame analyzation and dynamic adjustments of lamp power for black-level optimization. Catering to a wider range of user preferences, the H7850 has a brightness advantage with a 3,000-lumens rating. The H7850 projectors also support Acer's AcuMotion technology that enhances picture clarity in fast-moving scenes and reduces motion blur. It generates intermediate frames and inserts them between existing ones, which prevents unwanted flickering, making it ideal for watching the big game or action movies.
