Before this one we bought the FAVI RIO 2 projector and in comparison that one was like a children's toy. You couldn't set it up right. The resolution was way off, color non existent, and you couldn't use it for anything except movies. Forget about computer presentations. The letters were blurry and muddy.
To tell you the truth I was afraid we were not going to find a projector to suit our needs under a $1,000.
None of those were a problem for the Viewsonic. Granted this review is after a very short period of time. If it changes I will update this. However, as of right now, this projector is as good, if not better than the one I have at work which probably cost more than a $1,000. That one is a VieSonic as well but much bigger.
First of this projector is BRIGHT. You will have no problem displaying it in a room with light. Haven't tested it in a sun lit room yet though, but I would venture to guess that you wouldn't have a big issue.
My wife needed a projector that will do presentations and display her Macbook computer screen on White or Blackboard. No problem there. Letters are clear and bright. If anything this projector is almost too bright. Had to have a lower setting on the coloration.
So far I have tested DVD playback, a couple of presentations, and the wife is testing the overall use in the classroom as wee speak. Movies were good (even through VGA display...can't wait to have an outdoor movie beside the pool on the side wall), and presentations clear and crisp.
Oh and the size of the display seems like it could be huge. I was not able to test the actual distances. It says it could display a 250" screen. That's enormous. My test was around 55" screen size. Plenty good for classroom applications. I did rotate it slightly to the side and saw a much bigger screen and preserved resolution. So no problems there.
SO far A+++ on this projector. These ViewSonic ones seem really good for the price. I will update as we go along and report any problems.
