Avoid 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.
CAUTION:
Avoid screen burn-in. Do not display the same xed images on your HDTV
screen for extended periods of time.
