The ViewSonic Pro8400 is an advanced high brightness DLP installation projector which includes BrilliantColor technology to produce more vibrant colors. The Pro8400 delivers 4000 lumens with a 1920x1080 (1080p) superb image resolution, allowing it to shine in virtually any lighting situation. The Pro8400 provides maximum mounting flexibility with a wide 1.5X optical zoom adjustment and a multitude of connectivity options including Network Display, USB, and WiFi (optional WPD-100 Wi-Fi Dongle required). The filter-less design and long lamp life provide for easy maintenance and low total cost of ownership.
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.
Other Thoughts: Buy a different brand with better support especially if you want to connect to the projector using TCP/IP.

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 comparing to the NEC is that I think for upto a 100 inch screen, a 720p resolution is sufficient.
Other Thoughts: 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. The diagrams in the manual about the picture size, height above(below) the lens, and the distance from the wall, and zoom, are right on the money, so pay attention to the numbers before you buy. I have tested both HDMI, the composite, and component inputs.

Beautiful Picture - with a bit of a aim issue
Pros: Beautiful 1080 picture, 2xHDMI inputs and fast refresh rate, bright on wall even with daylight shining through blinds. PIP/POP for sharing 2 HDMI signals! - but also includes all the other inputs as well.
Cons: Aims straight with NO zoom, at MAX zoom the picture is High on the wall even having to prop up the back of the projector to get a picture straight on the wall.
Other Thoughts: I had RMA'd the first projector because of the aim issue, besides contacting ViewSonic about the issue and being told that this is not Normal, receiving a second projector with the same issue leads me to believe it is infact normal.
