Ok, so i wanna turn my room into like a home cinema type of thing. I have a wall space of 80" and want to know is it better to get a TV or a projector to fill that space? I'm thinking why not fill the whole wall with an 80" projector screen but then i'm told the bulbs on projectors don't last and they're expensive. I know nothing about this sort of thing myself so advice is needed, thanks.
