This way we are all on the same page. Although usually it's the HDTV, the source may also have settings that are adjustable for certain types of content. E.g. Comcast cable box, etc. YMMV
In the meantime, take a quick peek at the user manual online- pp.113-115, and also p.163

My new TV doesn't display the full picture. It cuts off the picture at the edges of the screen. I've tried to find a way to adjust it, but haven't had any luck.
Does anyone know how to fit the picture to the screen so the entire picture shows? Thank you!
