Ray, a liquid crystal on silicon(LCoS) pico projector from Ray Displays, features 10 lumens ofbrightness, a 20,000-hour LED light source, VGA resolution, a2-hour battery life, and stereo speakers. Measuring 0.7 by 2.3 by4.4 inches, the 5-ounce (with battery) Ray isn't much larger than adeck of cards; but at a distance of 5 feet, it can display aviewable 40-inch diagonal image on any light-colored surface insubdued light--and even larger sizes in truly dark settings. Overall, the Ray projected videos, photos, and other media fairlywell, but it earned better marks for displaying text than forrendering graphics. In an iPod PowerPoint presentation, forexample, the Ray displayed bright, legible text in various fonts,but dull, washed-out color hampered its graphics quality. In motiontests, the Ray displayed smooth action throughout a screening ofthe Monsters vs. Aliens DVD, but the projector's muted color palette made the images lookless vibrant than in the original film. The Ray's built-in speakerswere rather weak at any significant distance from the projector;we'd recommend investing in a separate sound system for betterresults. Like most pico projectors, the Ray is a snap to set up and use. Itsstreamlined design includes a power switch and focus knob, a single2.5mm audio/video input, and a power input. It comes bundled with aflexible mini-tripod and various video cables for connecting theRay to mobile devices. To connect the Ray to an iPhone 3GS or a fifth-generation iPod Nano that uses a 30-pin connector for video output, however, you'llneed to use a third-party cable (not included). Not surprisingly, the low-cost Ray lacks some features thathigher-priced pico projectors--notably the 3M MPro120 , the Aaxa P2 , and the Aiptek PocketCinema V10 Plus --provide. For instance, the Ray has no built-in memory or cardreader for displaying stored content, it has no VGA port forconnecting it to a laptop, and its rechargeable battery isn'tremovable. Once its 2-hour battery charge is exhausted, you cancontinue to use the Ray via its bundled power block, but rechargingthe dead battery may take upward of 5 hours. Most competing pocketprojectors use removable batteries that take only 2 to 3 hours torecharge. Ray Displays offers a typical one-year warranty on theprojector and battery. The Ray is worth a look as a low-priced, no-frills pico projectorthat displays readable text but mediocre color quality.
