question about shadows and blacks on 8350

i recently bought a 8350 and for the most part im very happy with it. the only problem that im finding is when im watching a movie with really dark scenes that may have a portion of bright light in it i get a foggy/blotchy looking image around the lighted area. i am not sure if this is just a settings problem or just that the projector is too low end to have better shadows. i have also checked and cleaned the lens and filters, so any ideas would be great!

thanks, keith
