great value, great quality if you only need 4000 lumens

Summary: If 4000 lumens is all you need then this is a great projector for you in an office/conference room setting. We have put several into different clients in boardrooms and conference/presentation areas. They have no compatibility issues with PC, Mac, appleTV, and various HDMI matrix boxes we've used. This fits all the different kinds of ceiling mounts we have tried (we usually use Chief), and the keystone and screen motion adjustments work well.
Summary: By far the best projector I have ever owned or used, in every respect. Produces a beautiful, perfectly sharp, brilliant image. Love the adjustability of the throw length of the lens. It means I can correct for the distance between the projector and the screen to some degree, and not have the image limited by the space of the room I am in. Do yourself a favor, if you don't buy this projector, buy one that has an adjustable image throw length on the lens.
Summary: Fantastic projector we have it projected on wall 108 across and it looks stunning. The 4000 lumens is incredibly bright and the picture does not degrade when the blinds are open during the day. We got this projector to replace a viewsonic pj1165 that did not have a hdmi connection. Very happy only disappointment is that the Roku is not compatible with projectors.
