I have a Mitsu 55613 TV. I bought it just before a bunch of hurricanes and have been too busy to really figure it out. I have a bunch of viewing modes, Normal, Stretch, Stretch Plus, Standard, Expand, and Zoom. Maybe a few more. My confusion comes in when Broadcast TV has black bars on the top and bottom of the screen. They are not always the same size. Typically, I use stretch plus. That is the mode that fills the entire screen without making the middle look distorted. Sometimes, I use normal when I want to make sure that I looking at the correct picture. How do I know which mode to use with the different size black bars? FYI, I don't mind the black bars, I would much rather have the correct picture.
