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...
Summary: 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. However a distance of 16' from the wall projects a 12' image at max zoom, and is most definitely a beautiful picture!
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. The image is that the lowest part of the image does not move with the zoom like normal projectors do, the bottom of the image is always the bottom, causing the zoom to make a bigger picture upwards only.
