Image persistence

•
Please

Image
Persist ence
occurs when

“ghost”
image of

emains
visible on the scr

Unlike

LCD

constant images being displa yed for
a
long period of time should be avoided.
T
o
alleviate
image persistence, turn off th e monitor for
as

as
the pr
evious
image was displayed.
For
example,
if
an
image was on the monit or for

the monitor should be turned off for
one
hour to
