BTW, Great PJ! I love my NX5.
My viewing distance is 18FT (room is 26' x 22' x 14' ceiling). Screen size is 150".
And my wife complains all the time that the 150" screen is TOO BIG (from 18' distance) !!!
I am glad I didn't get a 200" screen.
So you might want to factor in your wife if she is going to be watching movies with you all the time.
