The visual qualities of digital channels may vary depending on the original production method

originally an analog program which has been converted to digital.

The HD(High Definition) caption that appears when switching channels or when pressing the
Information button on the remote control means the selected channel is a digital channel. If the
broadcasting station converts an analog signal into digital and transmits the signal, the visual
quality may not be perfect.
If Just Scan is selected in some external devices, a distorted picture may appear in the corner
of the screen. This symptom is caused by external devices, not the TV.
This appears when you press and hold the EXIT button for a while. The product settings are
reset to the factory defaults.
