connection, if it is supported on your TV.

Screen burn-in
Images such as letterbox bars or side bars, bright closed-captioning backgrounds,
station logos, or any other stationary images may cause the display in your HDTV to
age unevenly. This is known as screen burn-in. Refer to the owner’s manual that came
with your HDTV for more information about avoiding screen burn-in.
CAUTION: Do not display the same fixed images on your HDTV screen for extended
periods of time.
