Good warranty for projector and bulb 3D capable Can run presentations from a USB stick Cons Rainbow effect in video The Casio Signature XJ-M provides a good data image quality, and video suitable for typical business or classroom presentations. This 3D-capable projector has a good range of connectivity choices, including the ability to project via Wi-Fi or from a USB stick. The projector is rated at 3, lumens and has an XGA 1, x native resolution.

Instead of producing red, green, and blue using a standard lamp and a colour wheel, it produces red with LEDs, blue with lasers, and green by shining the blue laser light on a phosphor. Its optical system directs the red, green, and blue light to the DLP chip, and out of the front lens.

The lifetime of standard lamps typically ranges from 2, to 5, hours, and replacement bulbs can cost several hundred pounds. It comes with a soft carrying case, complete with a pocket for cables. When you plug in a USB drive, the projector will automatically switch to it and give you a menu of options to find the files on the stick and show them. Other connectors include an HDMI port for a computer or video source, and a VGA port for a computer, which doubles as a component video port.

Image quality The XJ-M is bright enough to throw a fairly large image even in a brightly lit room. I did most of the still and video image testing under cinema-dark conditions with the projector about 8 feet from the screen, projecting an approximately 70in diagonal image.

In general, the projector did well on our suite DisplayMate tests. Colors were a little dull in Graphics mode; some images with white or grey backgrounds showed a trace of green tinting. The image was brighter and colours were bright and well saturated in Standard mode, though there was also more tinting. Some yellows looked mustardy. The XJ-M did well on our text tests, with type readable if a bit blurry at our smallest white-on-black size.

The XJ-M, like all single-chip DLP projectors, has the potential for showing a rainbow effect in which light areas break up into little red-green-blue flashes when you shift your gaze or in moving images, particularly ones with bright areas against a dark background. Though I saw the effect in data images, it was not severe enough to be an issue, even to people who are sensitive to it.

The XJ-M is adequate for shorter video clips as part of a presentation. I frequently saw rainbow artifacts in video scenes, more so than in a typical DLP projector, and people sensitive to the effect will likely be distracted by it. Casio sells its own branded glasses, although active-shutter DLP-link glasses are available from other manufacturers for considerably less. They both have the same generous set of connectivity choices.

On the downside, both showed significant rainbow effect in video. Verdict The Casio Signature XJ-M is a good projector for classrooms and conference rooms, able to handle almost any data presentation and show passable video. Its light source should last the lifetime of the projector, saving money in the long term over projectors with conventional lamps that may need to be replaced every few years.
