I be replace a older projector use in a business environment . the ViewSonic Pro8200 offer a lot of feature that I want -- mostly the hd\/1080p level of projection , plus good sound capability . in all area -lrb- except sound volume -rrb- this projector look like it will be a wonderful replacement . setup be very easy -lrb- I be use Windows7 Enterprise -rrb- . on the occasion of first usage , several people comment on the quality and improve visual impact of the image . my only modest disappointment be that the speaker do not put out as much sound as I be expect . I be hope not to have to take extra speaker with I -- the sound output be sufficient , but just barely . the multitude of connective possibility be amazing !! the inclusion of a hdmus cable with the projector be great . I really think I be go to enjoy use the Pro8200 very much .
