do screens still suffer from 'burn in'

Discussion in 'Photoshop Tutorials' started by fractalenthusiast, Sep 26, 2007.

  1. (Apologies if this is OT, but since it's about computers, there are a
    zillion newsgroups I could have chosen - I just happen to know this
    one well).

    At the college where I work, I often have to work in a room that has
    100+ computers in it.

    When they're not being used, they display a dialog box telling you how
    long a session is available.

    This box is programmed so that it slowly moves around the screen in
    little jumps. With over a hundred screens doing this - and not in
    phase, either - it's really annoying. No matter where I sit, I can see
    them out of the corner of my eye.

    I'm thinking of going to the IT department to ask them if they could
    get these boxes to just stay where they are, but before doing this, I
    want to be sure there isn't a good reason why they're like this.

    In the old days, anything in one place on a screen would eventually
    burn in an image, which is why screensavers were invented. But I've
    heard that burn-in doesn't happen anymore. Is this true?
    And if not, would there be any other good reason for these boxes to
    have to move about?

    The screens here are very flat ones, about a year old, BTW.

    Thanks in advance.

    Modern CRT screens (if you can call them modern) are not supposed
    to... and LCD-screens are certainly not supposed to.

    Still, I've noticed that the flat *LCD* screen at my work -- that
    pretty much
    shows the same thing all day every day -- appears to have been "burnt
    in". At least you can see a permanent "shadow" of the edges of the
    window it usually displays. Honestly, I didn't think that would be
    possible on a LCD-display.

    The different technology -- and the better grasp on the old CRT-type
    technology -- *should* prevent it on all modern screens, but it
    appears
    that it doesn't. (Though I guess a LCD-display can't actually become
    burnt in as the old CRT ones did, but the result seems similar.)

    Hi,
    I have heard that too and I don't know about LCDs but I do know beyond
    any doubt that if you leave the same pixels excited on a CRT, even a
    modern one, that area will be visible with either the monitor off or
    showing a bright screen - I have seen it.

  4. Hi All
    I've read that flooding the screen with a bright white image, just what in
    the old days would have been called a "raster" will cure that. It may take
    a few hours of the white screen but it's supposed to fix the problem.

    I didn't think an LCD would burn in, but I'm not certain. As for those
    CRT's, I think it would be best to just blank them after a preset
    non-use period. The log in or session time notification would come up
    with keyboard or mouse action. I see no reason to have anything on the
    screen during non use for any type of display (except perhaps for
    entertainment value).

    My practice for LCD screens is to have them turn off (in the Power
    Options Properties box) after some period (10-30 minutes or so) of
    non-use. No screen saver. Reason is that the light source behind many
    LCD's is fluorescent and gets dimmer as more hours of use accumulate.

    Hi John,
    That's interesting. I got one a few weeks ago that was so bad I just
    tossed it. Now I wish I had it back. It was really bad though. The
    machine must have sit idle for years.

    Thanks,
    Ron
