I know this is probably talked about over and over, but I don't have time to search through here like I would like to. Basically my simple question is that when you purchase a blu ray or dvd or even download a torrent they come in different aspect ratios. My projector is a 16:9 projector. When I watch my HD tv stations the whole projector screen is filled, but when I put on a movie with whatever aspect my projector goes to 16:9 or even 4:3 with older dvd's and I get the black bars. Is it possible to make it the whole screen instead of 16:9?
