Summary: White dots. I got 5 of these projectors for our small school, and all 5 had the white dot problem. Fortunately I actually bought the extended warranty, so I'm only out shipping and warranty price, but what a pain. Do not buy this!
Summary: After 2.5 years of moderate use, the projector is unusable because of stuck pixels that are proliferating across the screen. There are about 50 of these with new ones appearing daily. My previous projector from Dell lasted twice as long. This will be my last ViewSonic product.
Summary: I have this projector as a replacement after having the same issue that is all over the internet! (white dots, dead pixels that multiply over time) IT IS HORRIBLE!!!! Works fine the first few months and then all these pixels start going white, and their warranty process takes a few months to get through!!! Only for it to happen all over again!!! STAY AWAY AND SAVE YOURSELF THE TROUBLE PLEASE!!!
Summary: Our company has had to replace over 20 of these projectors. When they work, they are decent, but they have two known defects: 1. Will not power on or 2. Display tiny dots all over the image I would not recommend this product.
Summary: Viewsonic does NOT stand by thier products. We received this projector 5 months ago as a replacement for another Viewsonic projector that started giving us problems. Well now, only 5 short tmonths later we are experiencing the same exact issue and Viewsonic refuses to help us. The problem we have experienced with both issues is that white dots (pixels) start appearing on the screen.
"3D ready" is at best misleading and at worst a LIE!!

Summary: If you are looking for a projector than can play 3d movies...keep looking! This projector must be connected to a computer to function so forget 3dtv or blu ray. If you have a desperate need for 3d powerpoint presentations, this may be the machine for you. Otherwise, its a complete waste of time and money!!
