Expert review by : Tony Hoffman (



As a portable data projector for business or classroom, the NEC NP-V311W provides 3D capability and good image quality.

Good range of connection choices. 3D capable. Good data image quality.

Significant rainbow effect in video. Lacks port for USB thumb drive. No carrying case included.

The NEC NP-V311W is still a very solid model for classroom or conference-room use, and if you do need 3D capability it could well be your projector of choice.
