EPSON EB-W31

HWM (Malaysia) - - TEST -

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.
