The previous image
remains slightly visible
on the screen
• This phenomenon, called “image
sticking” is normal if the same
image has been on the screen for a
long time. The ghost image will
disappear after some time.
Over 10 hours operation with the
same image content is not
recommended. Switching on DPMS
on display and PC and activating a
good screen saver may decrease the
risk of image sticking (image
retention).
• A slight case of image sticking can
be solved by continuously displaying
a full white image during a number
of hours.
