If you have a standard definition TV set and an HD set-top box, your aspect ratio (the screen size displayed on your TV) may change when Auto HD is enabled.
To fix this, turn off Auto HD using the following directions:
- Press the Settings button on your remote.
- Scroll using the right and left arrow keys until High Definition is highlighted.
- Scroll using the up and down keys until Auto HD is highlighted.
- Press the Select button on your remote to turn Auto HD on or off.
