Those are beams in the middle.
The the first beam in the top pic is 6 feet 2 inches from the floor & the 2nd beam is 6 feet 6 inches from the floor.
The wall behind the TV is 8 Feet 4 inches from the door to the other side & about 6 feet 8 inches floor to ceiling .
I am thinking to get a Epson 5020UB since so far it seems like its does not have the plague like the 8700UB. Can I project a 100 inch image diagonally ? The lighting is not an issue but wondering if should paint anything black? Newbie here please help.
