we buy this ViewSonic PJD5122 projector to replace we older projector that be maybe 5-7 year old . what a amazing difference !! the brightness and picture quality\/sharpness be outstanding . I do not think we really realize how bad the old one be get until we start use this one . anyways , the pjd5122 be very easy to set up , adjust and operate . we have only use it twice so far for company meeting , yet everything so far about it be outstanding and above we expectation . -lrb- we use it for PowerPoint presentation , Excel spreadsheet , photo and a occasional video . -rrb- we would recommend it to anyone look for a excellent projector for a great price . definitely 5\/5 star .
