Lots of settings discussed but read http://forums.cnet.com/7723-13973_102-297796/just-scan-picture-sizing-for-samsung-ln-46a550p/
I have a Samsung TX-82782H HDTV. My issue is it cuts off the picture on the sides. It doesn't bother me much watching TV, but video games it ruins things because there's tips, maps, etc that are cut off. This happened with my Xbox 360, and now it's happening with my Xbox One. They are both hooked up by HDMI. I have set the at 16:9 and 4:3. It's not zoomed in or anything. No matter when I do, it cuts off the edges. I've heard of something called overscan that can supposedly fix this issue, but I do not see this in the limited menu offered to me. If I can't fix this, I will have no other choice then to buy a new TV, which I would hate to do because besides the sides cutting off it's a fantastic TV.
