Good article but one thing on the DLP. I read somewhere that if get above or below eye level, the brightness starts to drop off. I wanted to check this out, since my son likes to sit on the floor and play his GC.That's absolutely valid - but it's also valid for nearly all RPTVs due to many using a "type" of fresnel surface screen (inside) for focusing the image to a viewable area and a lenticular screen used for reshaping and directing light output within the target viewable area.
