With my TW8200 projector displaying "BLANK" black image, I hover my hand in front of the projection path to cast a shadow on the screen. The shadow is blacker/darker than the projected black image. Is this normal for projector at this price range? Am I demanding too much? I know JVC do have uber black...but I'm not sure how far Epson is from the elite group. FYI, this is my first projector.
