Why screen sever?

Question

Does the screen indeed needs a screen sever? Come on computer guys, reply this Q. Is there any scientific explanation?

Answer 1

Screen savers are indeed overrated, and I believe it is better to simply set up your monitor to turn off after a reasonable period of time, for several reasons.

You can experience Screen-Burn on an older CRT (bulky style) monitor. This means that if you leave your monitor on long enough and always keep your iTunes on top, when you close your iTunes one day, you'll see a faint image of where iTunes was that will never go away. LCD's and plamsa screens can experience this is well, although it's called "image persistance".

Also, having your monitor turn off will save you money and your electric bill and help to save mother earth.

Answer 2

It is screensaver, O.K.

Before the proliferation of LCD screens, most computer screens depended on cathode ray tubes (CRTs). Images on a CRT monitor are generated using electron beams which are emitted from electron guns at the back of the tube, and manipulated by electromagnetic fields to form images line-by-line on the phosphorescent screen many times per second. In some situations the images displayed on the screen constantly change, but in other cases some areas of the screen, or the screen as a whole, change very little (the taskbar in Microsoft Windows, for example). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen. Televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.

Screensaver programs were originally designed to help avoid these effects by automatically changing the images on the screen when the computer was not in use (thus "saving" the screen). They can be usually set up to launch automatically, waiting a specified amount of time after the last keystroke or the last mouse movement made by a user. The screensaver then blanks the screen, or more commonly produces animation effects, thus avoiding any "fixed" images. The screensaver remains active until a user presses a key or makes a mouse movement. At that moment, the screensaver closes and the former screen contents are restored, allowing the user to work again.

Answer 3

If you have a CRT (Cathode Ray Tube) type monitor, the screen can get BURNED IN with the persistent image. Some Plasma screens also can get BURNED IN with the persistent image. So a screen saver is useful for these types to change the image to prevent that burn-in.

But if you have an LCD monitor, this does not happen. So turn your Screen Saver OFF (if you want). An LCD monitor also uses much less power and lasts much longer (if you take care of it properly). So get an LCD flat panel monitor TODAY.

Good luck and Happy Computing!

Answer 4

Screen savers should be designed to vary what appears at any given point (or pixel) on the screen at any given time, not "burning" an image into the monitor as was a problem with CRT (tube) monitors. I don't know that it's an issue with plasma or LCD monitors but I'm not willing to gamble on it either.

Answer 5

Yes you should use a screen saver because if you leave your PC on all the time and do not use a screen saver you will end up burning desktop impressions into your computer screen. Good luck. Mikie.

Answer 6

today your screen don't need a saver anymore - it was necessary to keep old monochrome monitors from 'burning' the display (still-)picture into the screen. you could see it even when the mon was turned off!
new screens don't do that anymore - you can use a screensaver 'cause it's fun if you like!

Answer 7

no the screen doesn't always need a screen saver but you should put one on just to look cool

Answer 8

No you do not have to have a screen saver I didn't for a long time.

Answer 9

It keeps screen pixels in good working order.
