After doing some research on the net I came on the ACER P1340W and can say he has absolutely met my expectations. The projector seems to quality, the workmanship is impeccable. And the included accessories (cables, bag) is perfect. Small gripe: there is no lens cover and there is only a "Quick Guide" with minimal information. One can indeed download the manual on the internet, but if you're looking for something and just no Internet at hand has the annoying - me at least. Unfortunately, this is generally a trend for devices. Otherwise, very bright image and "Great Wall" still super in the resolution. Even in a bright environment, the light intensity is sufficient. When connecting the PC or TV is due to the extensive connection options easy super, only mitgebrauchte speaker is a bit "weak chest" - to look in a quiet environment although probably sufficient, but for the great sound can PC boxes right on be connected projector. On balance I would recommend the Beamer definitely, I do realize that there are certainly in a higher price range even better, but for my purposes to have namely from time to time cinema feeling and to be mobile, the device top and exactly what I wanted.
