Better to leave LCDs on or off??

    I was wondering whether it's better to leave LCD monitors on or off when not using them, i noticed mine puts out a pretty good amount of heat and i didn't know if that was bad or not to leave it on all the time. Anyone have an answer for me?

    Sorry I don't have a real answer, but why leave it on if you're not using it?

    off.

    if you are only stepping away from the computer for 10-15 i'd leave it on but other than that switch it off.

    What Mob said. Actually, just program your computer to shut off the LCD automatically after 15 minutes or so, and stop worrying about it.

    In any event, LCDs don't suffer from burn-in as badly as old-style monitors do, but the liquid crystals can still get permanently polarized if they show the same image for too long, so one way or another, you don't want the thing to show your desktop for a week straight.

    +1 for setting it to shut off after 15 minutes.

    Or doing it manually.

    Leave it on all the time... Just kidding. At my college we actually had 2 different LCD monitors burst into flames after being left on all the time, so my CIS teachers were always sure to tell us not to leave them on.

    I'm sure the LCD monitor is incurring no damage from being incessantly on but, for energy considerations, a timeout of the manner that every on this thread has suggested is a good idea.


    I'm curious to know whether LCD monitors suffer from burn-in at all. From what I know of the technology, I don't see how they can be susceptible to such a thing...

    LCDs do burn in -- but not to the same degree as CRTs or Plasma.

    The backlight has a MTBF so turning it off or using power saving WILL increase it's lifespan.

    ...but how? That doesn't make any sense. I highly doubt that the liquid crystals can retain the helical structure without the electrical current and colour filters aren't known for their burn rates...

    You may highly doubt it, but the liquid crystals nonetheless don't stay liquid forever when exposed to constant stress.

    Neither your post nor that article explained why they burn in...

    So... You're saying that the liquid crystals do maintain their helical structure after the current is removed? In other words, if you charge the liquid long enough, they will form a permanent crystal lattice?

    you would probably need to keep a still image on an lcd screen for a long time to get the pixels to stick

    i'm guessing that a program like pixel fixer would help correct most problems if they do occur.

    Both your graphics card and monitor had to support it. My ATi Mach32 let me do that.

    Put simply, they become "stiff", losing their ability to switch on/off. I posted the long ass explanation in a previous thread if you want to search it, or use Jolly's link, or google "LCD Image Persistence". I can say, from personal experience, that they do "burn in". We have some monitors at one of out DR sites that never turn off and 360 days out of the year show a login prompt. On the other 5 days that we are at the site doing a recovery exercise, you can see that damned login prompt burned in clear as day.

    That's not a real burn in, that's a stuck pixel. It can happen on a brand new LCD that hasn't been turned on before. It's hardly the same thing as a CRT burn in, though the effects are similar.

    Calling it a burn in is like calling MP3 of some talk show posted on a website somewhere with an RSS feed a podcast. Stupid labeling for something that already has a name.
