Some of the reasons why your picture may not fit on your screen:
- Viewing an SD channel on an HDTV will show black bars on all sides of the picture
- If you are currently tuned to an HD channel, the program airing may not be available in HD (the picture will return to normal once the broadcast is complete.)

If you have an SDTV
- SD programming broadcast on an HD channel will have bars on all 4 sides.
- Tuning to the SD version of the broadcast will result in a properly sized picture.
