Are Screensavers necessary and still needed?


  1. Actually and LCD can also get screen burn. Just takes longer. I know this for a fact, since we have on at our office with screen burn. Same information displayed 24/7 for over 6 months on an LCD, and it will begin burning it in. The LCD monitor was almost never turn off and a good portion of the information, such as window frames or titles didn’t change, only content in the middle.

  2. They have not been necessary or needed, not even with CRTs, since Windows 95.

    All one needs to do is simply set the monitor to tun off after a specified time in the Windows power settings. Not only saves your monitor….but also reduces the demand on your processor by actually letting it idle rather than running a screen saver.

  3. Unlikely.

    While LDCs and Plasma displays do have a image retention issues similar to “screen burn”…(called images persistence)…it is never permanent and can be cured by simply turning the display off and unplugging it for a couple of days.

  4. @AnandK, Thanks for the article it was informative. I also put the fish tank as my new screen saver after I finished reading it.

  5. What a confusing article. There is a good reason to keep the monitor on and to use a screen saver. First, if the screen is off people tend to just switch the computer off when going home. Since the screen is off there can’t be a program which needs a proper shut-down running, right?
    Secondly, leaving the computer open to anyone who only has to turn the monitor back on is poor security. If you leave the computer alone often, use a screen saver with password unlock.
    Safe from hands with ill intentions and safe from unintended but still inappropriate shut-downs.

  6. ” saving each Ohm of energy is a necessity.” The Ohm is a measure of resistance, not energy. You might say Watts instead. (a measure of power)
    I use a screen saver at work, because I can display pictures of my interests. I am supposed to lock the workstation when I leave it as it is, so no it is not required. The monitors are set to shut down (standby) after a half hour anyway. Reviving the computer turns them back on, so you can log back in to the computer.

  7. Normally, when I leave my computer, I lock it. All you have to do is to press Windows Key + L. That will keep people away from peeking into my computer because they’ll need password to unlock the computer.

  8. LCDs -CAN- get screen burn in. Luckily it’s not persistent as in CRTs. Most of todays monitor manufacturers embed a ” PIXEL SHIFT” solution to avoid this

  9. If screensavers are no longer needed why when I mute my Samsung LED tv does the mute speaker icon move every few seconds? According to the manual it is to prevent screen damage.

  10. Time to rant and rave. Actually I would like a screensaver and would also like my computer to sleep when I instruct it to but since loading Windows 10, this is a big problem with many others including myself. Come on Microsoft we need a fix for this problem.

  11. Because someone might leave the TV on for days or weeks at a time- say, at a restaurant that displays the news constantly. But it takes days at least for any burn in to occur (more often known now as “image persistence”, or “transient image persistence”, the latter of which is temporary). Computer monitors are rarely left on for that long nowadays, what with power saving options that are built into the OS, or the monitor itself even, that can turn it off or at least dim the display; even then they are usually in motion from usage or background programs, which shift the power state.

  12. Why would people switch the computer off if the screen is off? That’s some serious old-school thinking there; most people at my workplace jiggle the mouse if the screen isn’t on. Its almost universally accepted that if the monitor is off but the power light is on, then just the screen is off. Only people I’ve seen turn off the computer when the monitor is off are kids.

    Plus you CAN secure the computer by automating it to “log out” or at least “lock out” after a long period of inactivity (15~30 minutes if you’re paranoid or have work-related stuff on it; up to an hour if not). Plus, whenever its allowed, people often use encrypted flash drives to store information off the computer, instead of leaving it physically where someone can get to it quite easily. So no, it’s not really that insecure.

    Additionally, I’ve come across a really weird problem since upgrading my home computer, where the screen saver will accelerate until it freezes up entirely. So I’ve just done away with the bubbles and ribbons entirely, and reconfigured it to shut the screen off after a period.
