Video Review: Casio Super Bright XJ-S57

A high-brightness projector tucked into a small form factor.

Similarly, the S57's scaling was very good, but only if the source was XGA or SXGA. With higher- and lower-resolution sources, I noticed more artifacts on fine text and images than I would like. Of course, XGA and SXGA are likely to be the most common resolutions that the projector is called on to display.

I measured an impressive contrast ratio of 1463:1 in Presentation mode; this was again less than what the company claimed, but it's within an industry margin of error and effective enough in its own right. The S57's grayscale ramp was also fairly good, particularly for a high-brightness projector, with only a little of an “S” shape at the top between 90 IRE and 100 IRE. On the other hand, color temperature was variable with a range of more than 1000K as brightness increased from black to white. Clearly, that's an effort to compensate for the extra light that Casio is moving through the projector.

Color performance was something of a mild surprise, at least in terms of accuracy. Green was a little undersaturated and blue was a little toward green, but red was right on in my tests. The secondary colors of yellow, magenta, and cyan were surprisingly good for a high-brightness projector. The caveat is that while the color is fairly accurate, saturated colors dramatically limit the light output of the projector by negating the huge white section of the color wheel. The sum brightness of pure red, blue, and green measures was less than 50 percent of the brightness of white.

Of course, Casio bills the XJ-S57 as the Super Bright model, and it has a second Super Color model that could be a better choice if the use will be more heavily oriented toward displaying photographs and other colorful images. The Super Color model uses a six-segment color wheel that includes red, green, blue, yellow, cyan, and white — but even with that model, the white section is the largest of the six.

Casio has been building a projector brand that focuses on road-warrior presenters and that leverages a very slight form factor that can be slipped into a bag and carried anywhere. However, that same super-slim form factor, high brightness, and a few helpful setup features — such as powered focus and zoom, serial control, and a USB viewer — could make the XJ-S57 and its Super Color sibling very practical and low-cost installation projectors as well.
