I want to buy a projector, preferably an HD 1080p one that is similar to the projector in this review. I find it hard to believe that a 1080p picture can be projected onto a screen like this. If the projection isn't a perfect 1080p then I don't want it and would go with the 1080p LCD TV. Is the picture comparable to an LCD HDTV or is there a noticable difference?
