when I first get this product , I think it be not work , because I have not adjust the lens . of course I feel like a idiot when I do , but I also feel like I be on top of the world when I do , too . the clarity of this projector be second to none . if it be hd ready , you can plug up to it which be the simplest way . I hook up my Mac Mini and my Sony to it , and after a little over a month of usage , I still can not believe how vibrant the picture be . plus , in the simplest form of the concept of a projector , you do not need to lug around a T.V. All you need be a wall . bulb life I have not see yet , but it seem to be pretty nice , because it 'll sleep itself the same time you computer sleep itself with no screensaver and I can leave it on over a two day weekend and have no problem with it . like it , love it , want some more of it . on the other side of thing , I have now become addict to hi-def , so if it be not hi-def , it 'll show on this projector all the little detail and pixellation , but that be completely the fault of the quality of video or medium be show . however , if it be hd , get ready for a wild ride ! Ideal for anyone start up or want a home theater . Optoma , you have certainly win I over . buy it !!!
