As a business projector, the EP-731 is quite good. While resting just below average in our tests, it showed some strength in data projection, as well as a reasonably high score for DVD playback.

The Plus U4-112 suffered from some persistent problems when we tested it, including some noticeable moire and thick banding that showed with highly detailed test patterns.

Plus Corporation's U4 136Z projector is a fairly small unit measuring just 53 x 190 x 239mm and weighing only 1.5kg, and while it can be held easily in one hand its got the goodies where it counts.
