the projector itself be very good . bright picture with the 2500 lumen but actually when I check on the viewsonic website it say 2700 lumen . the fan be not that noisey . for I its quiet . and I be also use the economic lamp option so the fan be on low and the brightness also on low but still with light turn off you get a bright picture . I project it on the wall for now still get the pull down screen from the rebate . the contrast be also good even on the wall . setup be quick from out the box only take I 5min less and it be on live ! well I read the manual before it arrive so I get the idea of what to do already . when it shut down you have to press the power button twice , one then another one with a bit longer press then it start the cool down , for a minute or 2 then it turn off fan and lamp but the power button will still be blinking blue let you know that it be still plug in . it blow warm air on its side . I have not try the 3d feature yet . it be very light weight easy to carry around and smaller than I expect . overall I be very happy with my purchase and I and my family be now enjoy a very big screen for movie in we bedroom .
