Precautions When Displaying a Still Image
A still image may cause permanent damage to the TV screen
Do not display a still image on the LCD panel for more than 2 hours
as it can cause screen image retention. This image retention is
also known as screen burn. To avoid such image retention, reduce
the degree of brightness and contrast of the >screen when
displaying a still image.
Watching the LCD TV in 4:3 format for a long period of time may
leave traces of borders displayed on the left, right and
center of the screen caused by the difference of light emission
on the screen. Playing a DVD or a game console may cause a
similar effect to the screen. Damages caused by the above effect
are not covered by the Warranty.
Displaying still images from Video games and PC for longer than
a certain period of time may produce partial after-images. To
prevent this effect, reduce the ?brightness? and ?contrast?
when displaying still images.
I thought that LCD's were immune to burn-in, that only plasma TVs had
this problem.
