Burnt On Images

How long on average does it take for an image to burn itself onto a LCD screen? :cool:

LCDs don't get burn in, unlike CRTs or Plasmas.

edit: excuse the double negative.

Yes they do but unlike CRT's it can be cleared in few minutes but refreshing the pixels with a screen saver or a game.

how is that a burnt-in image if it can be cleared by refreshing the screen?

[Yojo]

by that logic then, you could leave the same image on an LCD 24/7 without harming it and that screen savers, especially for LCD's are completely unnecessary?

On a slightly related note, are dead pixels caused by anything the user does to the LCD or are they a manufacturing defect?

manufacturing defect

With LCD's its not really 'burn-in' as with CRTs, they call it image persistence--which is similiar, but fortunately not permanent.

I had a little bit of image persistence happen on my LCD once...it scared the crap out of me at first. But it went away in a couple minutes.

Here are some things you can do to get rid of 'image persistence':

* Turn your monitor off for awhile (may take several hours/days/weeks)
* Use a 3D app or screen saver that uniformly "exercises" each part of your screen.
* Display a white image on your screen for several hours/days/weeks.

I got rid of mine by simply changing through different backgrounds, but in the future I'll probably just run 3Dmark for a bit and that should take care of it.

The only way an LCD could suffer from burn-in were if one image was on the screen for a really long time and a multitude of pixels became stuck over that period. It could happen, but is unlikely. In any event, LCDs are much less prone to burn-in than plasma or even CRT technology is. Acurax nailed the issue.
