Tap the picture and one of the buttons that appears cycles between three ways of fitting the picture to your screen:
- Fit — the whole picture, in its correct shape, with black bars where it does not match your screen. The right choice almost always.
- Zoom — fills the screen by cropping the edges. Useful when an old channel broadcasts with black bars already built into the picture.
- Stretch — fills the screen by distorting the picture. Everyone looks slightly wider.
Your choice is remembered for next time.
