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 ...
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.
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....
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.
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.
