As prices drop, consumers are increasingly buying digital projectors to cast big images in company conference rooms, home living rooms and backyard “drive-ins.” Two technologies—micromirrors and liquid-crystal displays (LCDs)—have been vying for these markets, but they are doing equally well in today’s home and business arenas, says Art Feierman, editor of ProjectorReviews.com. Both varieties can project sharp images from DVDs, digital cameras and presentation software such as PowerPoint. The choice depends on what buyers value most. In the inexpensive range (below $1,200 or so), micromirror machines may be slightly smaller and lighter and may project higher-contrast images. LCD machines may have better color accuracy, however, and run quieter and cooler. More expensive models of both types often compensate for any inherent technological weaknesses.
