I have been reading on this forum for years and have learned so much but decided to jump in and ask what I think may be an easy question. I have an InFfocus X1 Projector. I used it for a few months before deciding on the screen size and aspect ratio to go with. The projector is zoomed out all the way for the largest projection I can get. I ended up with a 7.5 foot wide screen by about 5.5 feet high this is at a 4X3 ratio. When I switch the projector to a 16X9 ratio the image looks stretched and is no wider than the zoomed out 4X3 ratio. Is this because I am zoomed all the way out?
