My problem was that in the conference room where the projector is to be used, the distance projector / screen is just over 2 m. Nevertheless, the projected image should rd. Be 2 m wide. The search was lengthy. Normal Beamer require approximately 4 m distance, short-throw projectors only max. 1 m. Both are impossible in said space. Dealer could not help me either. A call to NEC gave a tip for this device. And that was worth it. 2.4 m distance, image 2 meters wide. Clear and bright. Resolution can be adjusted. Many connection options, including two entrances. In addition, USB, LAN, ... image is also displayed on the monitor when the projector is still turned off (was with the predecessors of Acer and BenQ not so well read not be selected). The unit is very quiet, making fast a bright image, cools after barely. And the sliding door in front of the lens is also good, you have to protect against dust the lens ..., not always put on a cap. The device is quite large, but what bothers me in any way. If the bulb still holds the specified 5000 to 6000 hours, everything is super.
