screen? Thanks.

Once upon a time in the early days of computer the image on the monitor if
left stationary for a certain period of time would "burn" an image onto the
monior screen...the screen saver by constantly moving stopped this from
happening.
Todays screens are not so susceptible to screen burn in and people use the
screen saver more out of habit,to stop others from seeing their work or
???..it looks nice!!

Screensavers are used more for privacy now than for preventing screen burn.
If you left your monitor on in th eearly days nine times out of ten whatever
was on the screen would leave an image when the monitor was turned off -
hence screen burn. Nowadays the new monitors are not so suseptable.

It still applies. Leave a banner on a monitor for a year or two and it will still happen. You see it in shop windows. It's just in the past it happened quickly.

It doesn't (at least not very much). The name is a misnomer.

Back in the old days of mono monitors, if the same screen was
left in place unchanged for very long, the image would tend to
"burn" itself into the screen.

Modern color monitors are not immune to this, but the problem is
much less severe than it used to be. So the screen-saving value
of a screen saver is not particularly great.

In general, the only real reason for using a screen saver these
days is to keep curious eyes walking past your desk from seeing
what you've been doing.

And for all of those people out there who never get to see your
screensaver.. Check your power-saving options in Windows. If you have your
screensaver set to kick in after 15 minutes and your power-saver feature set
to 20 - only 5 minutes of screensaver. And the best is when you have your
screensaver set to kick in after your power-saver and it turns back on your
monitor. Nice.

I used to have an old mono (amber) monitor in my shop that I used to
illustrate burn-in.

The monitor was used for about 5 years on the prescription counter of
a local pharmacy. Even when the monitor was turned off you could read
about 80 percent of the information from the prescription entry form
that they used.

It comes from the old days when monitors left a "burnt-in" "after image" in
the screen (the days of those mono-chrome green/yellow/orange screens.
Todays modern monitors are not affected so much, and therefore screensavers
are more a mode of 'entertainment' rather than practical use.

Else they wouldn't have progressed to things like full colour animated
fish/underwater rather than "star fields" or the "Mystify" type savers.

You replied on July 18 to a question posted on July 8. That's ten
days later. You also said essentially the same thing that *seven*
others of us said on July 8 and 9.

The original poster almost certainly has long ago stopped looking
for answers to his question.
