There have been quite a few new projector and screen threads so I thought I would add mine.
Well my screen came yesterday. And lets just say it is a bit bigger than I thought. I ordered a 84" thinking that the screen would drop nicely between my two mains that are(were) set apart a little over 6 feet.
So the Yellow delivery guy comes with this monster of a box that measures over 90" long. Needless to say I'm nervous when I see that. I open the box only to see that the tension bar at the bottom of the screen is 84 inches.
That is a foot wider than I planned.

I have moved the speakers apart as far as I am willing and have found when they are toed in (thank god they are curved cabinets) that it will just fit. I will have to get a new mount for my tv so it is closer to the wall which will give me a couple of more inches.
So my point is that get the full specs of your screen (or any products) before you order so you don't have to go through this.
I can only imaging what my wife is going to say when she sees this.
