The unusual zoom lens allows for a wide range of placement options, and the included software and wireless connection hardware make the XJ-A a solid performer when it is inconvenient to drag computers and cables along on a presentation. When you switch the projector on, there is about a ten-second delay while the zoom lens adjusts to your last setting, and then a fully lit image appears without the usual gradual increase in brightness. It slips neatly into a slim briefcase and travels with you easily to presentations outside your office. Adopting a new semiconductor-based light source system combining a blue laser, phosphor and a red LED, we have achieved both high-brightness performance enabling projection in well-lit rooms and environmental friendliness with mercury eliminated from the light source. This source achieves high luminance safely by employing a phosphor device to modify the wavelengths and phases of blue laser light. New illumination technology The new and innovative semiconductor light-source technology developed by CASIO combines LEDs and laser light to create a completely new, mercury-free light source.

Port for USB thumb drives. Some data image issues, including tinting. Somewhat pricey. Relatively pronounced rainbow effect in video. Instead of producing red, green, and blue using a standard lamp and a color wheel, it produces red with LEDs, blue with lasers, and green by shining blue laser light on a phosphor.
Its optical system directs the red, green, and blue light to the DLP chip, and out the front lens. It comes with a soft carrying case for easy portability. It sports a futuristic look, with rounded edges and lens set far to the side. There are no manual lens sliders or wheels; you can change focus or zoom a generous 2x zoom either with the remote or from touch-sensitive nubbins on the projector itself. It has automatic keystone correction, though you can also manually correct keystoning through the remote.
You can run presentations computer free from a USB thumb drive plugged into the port. Testing I tested the projector from about 10 feet away from our test screen, where it projected an image about 60 inches, measured diagonally. The image looked slightly washed out, though still usable, when exposed to a fair amount of ambient light. I tested data image quality using the DisplayMate suite with the room darkened.
Quality was about average for an XGA data projector, though I noticed several issues. While I could bring the rest of the image to a sharp focus, the focus was a bit soft in the upper left corner. The smallest size white-on-black type was blurred enough to be barely readable, and it was a bit blurred at the next smallest size as well as the smallest black-on-white.
Colors were bright in Standard mode, though there was also a bit of tinting. Some grays looked slightly green, and white backgrounds had a mild greenish tinge as well. Switching from Standard to Graphics color mode reduced the tinting, but it also muted the colors somewhat. Switching from a VGA to an HDMI connection had no appreciable effect on image quality, which is good enough for typical business presentations, but perhaps not for ones in which exacting color is important.
Video was of a quality suitable for showing short clips as part of a presentation. The chief issue was the appearance of rainbow artifacts: Little red-green-blue flashes, especially in scenes with high contrast between dark and light areas. Few DLP projectors are totally free of it, and people vary in their sensitivity to it, but with the XJ-A it was a little more obvious than usual.
It would likely be distracting to people who are sensitive to it. Audio was of decent quality and of good volume for a 1-watt speaker, loud enough to fill a small to midsize room. The Epson W has better still and video image quality, and not being a DLP projector is free of rainbow artifacts. Between the two Casio Slims, if you want higher native resolution and a widescreen aspect ratio, the Casio XJ-A is the one to get. The XJ-A also had slightly more image quality issues in our testing.
