I have the Benq W770ST bought after a long and detailed research, so the short-throw projector. About the technology: as a player, I use the PS3 and the shutter glasses I have 2 pieces 3D glasses "BLUE HEAVEN" brand VIDIMENSIO Fourth Generation in 2013 and 1 piece BENQ 3D glasses f P6series / MP7serie.. Is illuminated with an electric screen 244x182 cm. Was seen: Thor 3D Tron Legacy 3D, The Hobbit An Unexpected Journey 3D, Merida legend of Highlands 3D, Ice Age 4: Continental Drift 3D Open Season 3D. My impressions: I am really flabbergasted, producing a sharp, color and high-contrast image of the projector. I had really concerns me to buy these projectors and not Full Hd Bamer. However, the picture is as sharp (at 110 ') that I can not imagine a sharper image. Also, I feared that the colors are not nice and the black is not black. But the colors are amazing and the contrast is excellent. A improbable 3D experience. Have the projector on SmartEco run on because I use it in the hobby room, which I can darken good. I also had doubts as to whether I am in favor of rainbow colors vulnerable, but I can not perceive rainbow colors, and not provoke. The shutter glasses are both at a high level, which I slightly prefer wearing the Blue Heaven. The Blue Heaven may occasionally times losing the sync., but find it again, but this contrast default at very high levels and color fidelity. The original glasses never lose Sync., but sometimes they make the colors differently there. I found it a pity that so few have evaluated the Benq W770ST, so I wanted you to describe my impressions. Furthermore plays my daughter often PS3 Move, therefore it had to be a wide-angle projector. By the way I can the noise of a fan here do not confirm, although here a video review is, which says the opposite. Perhaps this is also because the Beamer 2 meters is facing the screen and the fan slots are directed to the screen, but I'm sitting 4 meters behind the screen. I hope I could help you in your purchase decision and wish you also enjoy using this device. PS: About one click with helpful perceived review I would be happy.
