You can get a carpenter to attach your projector to the ceiling. If it is in the living room on one of the 4 Aramco compounds there are no chandeliers in the living room where you would probably put your projector.
May I send your contact info to a friend of mine who has a projector?
aerternum8, My friends wrote me back instead of to you.
They said their projector was sitting on a shelf not on the ceiling.
Also, they looked for a long time for a projector screen and could not find one here. They ended up stumbling on one in the souq area in an old camera shop about 5 years ago. Someone had ordered the screen and not ever picked it up. It was just lying diagonally on the floor in the shop in its box so it would fit in the small shop and he tripped over it. He asked about it and they sold it to him.
