    I've never used screensavers. I've just had my monitor sleep after a given period of time. It saves energy especially on my notebook.

    I usually just turn mine off when I leave or go to bed at night, I do a lot of random alking by and seeing an im and repsonding to it, so if I can leave it on all day without a screen saver that would be great. I just want to know if you can burn the screen with a LCD?

    It doesn't get burn like a crt does.

    But I know to unstick a frozen pixel, you use a program that switches it on and off rapidly. So I wonder if it could work the other way around.
    Leaving every pixel stuck on the exact same color over time could make some stick?

    If the blotch area was stuck pixels, I don't thing you wouldn't be able to see the image change in that area. It sounds more like a manufacturing flaw, or maybe shipping damage.

    Well it was a 19in widescreen, 5ms, 800:1 contrast for $180 shipped brand new so it is probably a manufacturing flaw lol

    The way I checked for stuck pixels on my monitor, is I opened up paint and expanded the image space to the size of my screen.

    Then I used the "fill" function to fill the entire space with one color at a time to see if I could see a the twinkle of a stuck pixel.

    With black, dark blue, red and lime green you would be able to see a stuck pixel, and I don't see any on mine.

    That's not so far off of normal prices that you shouldn't expect it to be correct.
    You should contact the place you bought it at, and rma it while you still can.

    I think I'll do that, it isn't so bad that I can't deal with it,, but the thing is brand new so it should be right

    Despite the misinformation in this thread, LCDs can burn-in. It's not as prevelant os CRTs, but it does happen. I recommend power-saving the unit.

    Nyet, Captain.
    On a crt, it literally burns the image onto the inside edge of the front of the tube.
    On an lcd, there are no temperatures capable of doing that. The only burn-in that could happen would be like I stated, where the pixels might get stuck.
    And that's called image persistance. Something that can be reversed by using one of the apps that switch the colors on and off at a rapid pace.
    And there is zero chance of that happening on a brand new lcd, unless it was a display model somewhere.

    wrong. They most certainly can "burn in" and it's not the same as a stuck pixel.

    and on this, we disagree.

    It's like trusting "howstuffworks.com". It gets the very basics of the topic, but I wouldn't trust it beyond that.

    I've seen the reversible type of "burn-in" on my laptop and desktop LCDs, but never anything permanent.

    LCDs can burn-in, yes. It has nothing to do with temperature.

    Jolly is right. I've seen LCDs in data centers that have had burned in images on them.

    They're not physically burned in though. Burn in was literally the electron gun
    burning an image into the inside edge of the glass.
    (or the coating on the glass, whatever)

    Needless to say, lcd's don't work that way. What happens is that the pixels
    get stuck. I challenge somebody to show that liquid crystals can "burn" an image into the panel material.

    Yep, we have LCDs and Plasmas at school with burn-in.
