I just bought a 32 inch lcd tv and swing mount that goes out 15 inches. How many degrees will it go?

I have a wall to the side of my bed and I want to mount it on the wall and swing the tv in front of my bed. The mount goes out 15 inches but the tv is 31.5 inches wide. Since the center point is around 16 inches is that extra inch going to really mess things up? My goal is to swing it 180 degrees but I know that won't happen. Any one have experience with this?|||simple physics man. u wont get the tv perpendicular to u or 180degrees cuz the arm is too short, but ull get it close enough and you wont notice a difference, the viewing angles of lcds are pretty wide. a few degrees wont mean a thing.
