NEC's U321H is a 3200-lumen ultra short throw projector that packs a multitude of features while delivering an extremely short throw distance for education and corporate applications. A complete interactive projector solution can be created using the optional NP04Wi interactive system (dual pens) with auto calibration. With its ability to be mounted to the wall directly above the screen on which it projects, this model helps eliminate the shadows and glare typically found with standard projection systems. The U321H includes a powerful 8W speaker, closed captioning and RJ-45 for remote management over a network, and its input panel includes dual HDMI, VGA.
