Short summary for those who are interested in the device: I read a long time test reports and reviews and I've - although all the volume is criticized for purchasing the Acer, although BenQ would have been very interesting. The key for me was the fact that the BenQ projector probably often have a dust problem, this will hardly criticized at Acer. I have now overcome the equipment in use and am. In Eco mode (perfectly adequate) super sharp, color intensive image. Fan noise is absolutely bearable (and I am very sensitive - for example, can not do anything with a loud notebook). In addition ... Great menu and all easily accessible via the remote control. Furthermore, in the top price range: 2 x HDMI input .. very important for me, because in addition to the PC and the TV can be constantly (on the PC) connected without changing plugs. Had ordered to the projector a 120 inch screen, but does not use. The image has been displayed perfectly on my living room wall (though I really wanted to look only on the size of the image). Have therefore to beat the image still further ado the wall in the display area painted white and not hung the canvas. Result .. wear-free "canvas" with more than 120 inches (see attached pictures - at a I have to compare my 60 inch TV in front of it.). Now I can surf from the couch comfortably on the Internet or daddeln or watch TV. For me as a gamer is a dream come true. Lights out, Elite Dangerous purely and start .. Oh .. rainbow effect I have been unable to discover and "smears" or the like in fast games either. In short ..'m thrilled. For questions, just let me know
