if you only want to use this projector to watch sport in hdtv , then I suspect you will be quite satisfied . in a dark room with hdtv it can be truly breathtaking ! keep in mind that you will not get a good picture until you have eliminate almost all surround light . but , the `` rainbow effect '' make watch movie almost painful . Whenever the movie have a bright light mix with a dark background you will not see a white light , but a fast-moving rainbow . I have not see this when watch sport . normal analog tv channel do not look very good on a project screen like this . even digital channel look grainy . but hdtv look awesome ! there be not really a `` screen door effect '' in hd to speak of . I get a huge 100 '' picture at about 14 foot away . at $ 700 , I consider this projector to be a bargain . even though this projector seem to be ideal for hdtv sport , I be concern about the ability to view future hdtv signal because this projector be not compliant with the hdcp stanard that may govern future hdtv broadcast . if that happen in the US , like it have in Europe , this projector would become worthless . the noise level of this projector be higher than I expect , but once the sound be on you hardly notice .
