Do any other RP91 owners have their vertical alignment off? Does anyone know of a way to adjust it (like you can for horizontal alignment)? When I watch movies with higher aspect ratios than 1.85:1 on my Elite 710, I notice that the black bar on the top is smaller than the one on the bottom. Is this by design? I guess it's not a huge deal, but I was thinking that if you can adjust the horizontal alignment, you should be able to adjust the vertical.
