Sitting just below the WUXGA-capable EB-U04 this year is the brighter 3,200-lumen EB-W31. Unlike Canon's LV-WX320, this EB-W31 uses 3LCD tech. In the past, we'd hand the color advantage to 3LCD projectors, and the size advantage to DLP projectors - but such differences are mostly negligible today. In fact, at 2.4kg, the EB-W31 is the lighter of the two.
The EB-W31 is well endowed in terms of connectivity, sporting a wide range of video inputs, including VGA, S-Video, composite, and HDMI. In addition, it has a USB Type-A port for connecting to peripherals, such as USB memory and Epson's own document camera. There's also a USB Type-B port for display and input control over just a USB cable.
The EB-W31 is able to sense incoming signals and turn itself on automatically and change to the correct input. Startup only takes a few seconds, though full brightness is reached in only about 45 seconds. The front exhaust is a nice touch to keep hot air away from the audience, and we like that the lamp lasts up to 10,000 hours under Eco mode (light output drops about 30 percent in this power-saving mode). There's an air filter you need to change; in most cases, you only need to change it when you change the lamp.
To nitpick, the projector has no built-in networking support, though the saving grace is you can add wireless connectivity via a separately sold adapter. Paired with the Epson iProjection app, which you can download from Apple App Store or Google Play, your can then walk around with your mobile device to conduct a presentation.
