The picture is good, for a decline of 4.5m it must give a screen width of 3m, the focal length is average (not melt or room to put a 3m). And adjusting the focal length mini mini, one gains / loses 3m 30cm projection. I think it is quite noisy, it would trap her. The sound output jack did not work, so use an output sound of the amp or the media center. At it's me XBMC - XBMC HDMI to Projo and audio to audio amplifier via jack. That is quieter but it'd be really great. He died quickly in eco mode (which is enough for me). J would have preferred a Benq but too short focal problem.
