this be a really bright projector and project very sharp image . need quite a bit of color adjustment out of the box but I get it to look really good . however , the DLP rainbow effect be very noticeable to both I and my son on this machine . what be odd be that we be replace another DLP projector and we do not see rainbow with the old one . the old projector be a SharpVision xv-z3000 -lrb- 720p\/1080i -rrb- . we think the reason for the DPL rainbow effect now be a issue with the BenQ vs. we sharp be that the Sharp be a 5x speed color wheel while the BENQ be only 4x speed color wheel . too bad ... I have to return the BenQ . I would have keep the BenQ if not for that since it be otherwise a really nice machine . we wind up get a Epson PowerLite 8500ub . very nice machine right out of the box -lrb- in term of adjustment , performance in general , sharpness , black , etc. -rrb- - a keeper ! Amazon be awesome with regard to take the benq as a return . thanks Amazon !!!
