I be extremely happy with this projector . I be use it at home to project across a 15 foot room onto a white wall . the picture come out to probably about a 8-10 foot screen . even without hd it look amazing . I have yet to try hd or 3d , but I be sure they will look great as well . the brightness of the projector be better than I expect . it do not quite work in the middle of the day with the shades open -lrb- darker color be hard to tell apart -rrb- . but it do work extremely well in a dim room . overall , very impressed .
