Summary: I have this projector and love it. I don't even have a screen, it is just projected 100 inches wide onto a tan wall, and it is super bright doesn't matter if the lights are on, the blinds are open, the picture is amazing. Colors are bright picture is sharp, couldn't ask for anything better for the money. You can spend more and end with less from other manufacturers.
Summary: Buy a different brand with better support especially if you want to connect to the projector using TCP/IP.
Pros: Nice bright display with pretty decent sharpness for a projector.
Cons: The projector failed in less than 1 week. It started automatically powering down after about 15 minutes of use with no overheating LED warnings. Viewsonic replaced it with a new projector with a manufactured date 1 year newer than what newegg sent me. Viewsonic wireless adapter only supports WEP (sold separately). DHCP server is either on or off so thier is no way to bind it to just the wireless card. vsPresenter software is NOT COMPATIBLE WITH WINDOWS 7! vsPresenter ...
Summary: Got one this bright, because my wife likes the light on. About 770 hours on the bulb in 5 months time, so just over 2 years of estimated bulb life left. The bulb has dimmed enough, that the bright white is no longer painful in a dark room. The unit is ceiling mounted and back far enough for a 100 inch diagnal.
Pros: Super Bright Picture. Bright enough to project on a matte white textured wall and compete with 150 watt light bulb turned on with out too much wash out.
Cons: Any loss of signal (i.e. switching inputs or sources) causes the projector to show the ViewSonic logo with an eye searing white background...not so great for a darkened room. Some flickering issues with the bulb. Occasionally forgets the settings; mine in on a UPS, so it isn't power loss related. Doesn't appear to have a picture any better than my NEC LT245 (1024x768). I know signal source has alot to do with this, but the NEC had an incredible scaler. My point in com...
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: I've tried everything I can to correct this but when I get text sharp in one corner, the other gets blurry. Thinking it was an axis problem, I adjusted it every way I could but now am determined that it is a problem with the lens. Also, it decides to go wonky and cycle through display modes (just guessing...like when you switch between theater and presentation modes) for a few minutes every few days. This is annoying when giving presentations.
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.
