my tv stand is 27 3/4" off the ground.

My viewing distance is around 10 1/2'

My eye level from the couch is 35-40" On side couch it could be lower (I tend to fall asleep watching tv).

Will the above be an adequate angle for the 60"XBR2 who's dimensions are
66x40x20.3 inches WHD?

I am considering upgrading from the 50"XBR which seems perfect to me insofar as viewing angle/distance, etc. (green blob issue)

I want to be as sure as I can before I go for the 60" that I will not be losing PQ or anything with my setup. I am not changing stands or anything like that.

I am also looking at the LED DLP by samsung, but it seems that it is sensitive to eye level (anyone with this TV please comment as well.)

Any opinions are greatly appreciated.
