In practical terms, the projector can be set on any of its 12 faces, so that the lens can be pointed horizontally for wall or screen projection, vertically for a ceiling projector, or at various downward or upward angles. The cylindrical-looking projector is actually 12-sided, with each side employing a twist that gives the C250i a stylish, swirled appearance. The second hole is for when the projector is in landscape orientation. One is on its base, and the other is on its side, a quarter of the way around from the lens. The C250i has two threaded holes that can fit a tripod. Above the lens is a small plastic focus wheel, which, alas, proved difficult to use to bring the image into precise focus. When so positioned, the center of the lens is 5.5 inches above the tabletop or other surface the projector is placed on, giving it exceptional clearance for a mini-projector. As it can be positioned in several orientations, I am treating its height as its longest dimension, and standing-tall portrait as its default configuration. A Projector With a Twisty StyleĪt 7.5 by 4 by 4 inches (HWD), the C250i is larger than other entertainment mini-projectors we have reviewed recently, and is suitable for either portable or home use. It’s flexible we just wish it were cheaper. It also can be tilted at a wide range of angles. When placed on its side, it projects in landscape mode. When set upright, it can mirror a smartphone’s screen and project videos and other content in portrait mode-in what Acer calls Auto Portrait Projection. At a glance, it’s hard to tell what kind of beast the C250i is: A vase? A twisted log? An all-black barber pole? But for all its unique styling, form does follow function, and it’s a fitting design for an entertainment projector/Bluetooth speaker mashup that’s unusually versatile in how it can be positioned. The Acer C250i Portable Projector has a highly distinctive appearance for a projector.

Its wide color gamut and up to 85 percent color saturation create deep color tones. The hybrid technology is a system of LED light and lasers. Hybrid laser-LED bulbs can achieve 20,000 hours of life with little or no picture degradation. Laser lights degrade over time as well, but much more slowly, leading to more than quadruple the average lifespan of a typical bulb. Bulbs degraded over time, becoming weaker and reducing color accuracy. Laser lights burst onto the scene in the projector market this year, making a bid to replace standard bulbs that were always the Achilles’ heel of that form of display technology. The K520 uses hybrid laser-LED technology that has an exceptionally long life span, reducing maintenance and lamp replacement costs while also providing a great picture. Acer America is about to bring lasers to the classroom, boardroom and any government offices that pick up the K520 hybrid laser-LED projector.
