Screen burn?

Question

Hi, and sorry if it's a stupid question. I've looked through the FAQ but can't find an answer. The questions is: do lcd screens suffer from burn? i.e. do I need to use a screensaver or power off the screen to prevent burn? I have an Inspiron 9400 which is on pretty much all day every day, and stands for hours at a time with only the Windows screen, that is, not being used. Thanks in advance.   David

my experience differs - obviously the specifics of it differ from CRT's.  i helped a guy with a bunch of dell LCD's at a local college. he had set the wallpaper as the school mascot and left these systems with this wall paper and no screen saver. after about a week the latent image of the beloved school mascot was noticeable when viewing anything on said monitors. the idea that LCD's do not suffer from image burn in is a myth. we were able to reduce and in some cases remove the effects by a process known as 'exercising' the pixels; set the background to plain white and leave it on for a couple of days.   http://compreviews.about.com/od/monitors/a/LCDBurnIn.htm   apple describes the 'exercising' process:  http://docs.info.apple.com/article.html?artnum=88343   clipped from another article: .   Here are some guidelines on how to take care of your LCD to prevent image persistence or burn-in Use a screen saver Change your background image periodically Use the power save feature of your monitor or Windows to turn off the monitor after a period of inactivity.  This extends the life of the backlight too. Here are some methods on how to reverse or remove afterimage or image burn-in Turn your monitor off for several hours/days/weeks. Use a screen saver that uniformly 'exercises' each part of your screen Display a white image on your screen for several hours/days/weeks

Thank you bweed6, I think, to be on the safe side, I shall use the power off option after 10 minutes or so. Thanks again for taking the trouble to reply.   David

Powering off is a good idea.

Burn in or not, the primary failure method of LCD displays (other than externally induced damage, i.e. breaking the screen from impact) is backlight burnout. CCFL lamps are difficult to replace and often expensive.

While "burn-in" is prevented by ensuring that the displayed image is always changing, backlight burnout can only be postponed by dimming or turning off the backlight.
