Screensavers are now obsolete?!?!

Hey there, this may be a stupid question, but what is the purpose of screensavers anymore?

I thought they were used to prevent burn in images on screens from happening, and also to prolong the pixel life on LCD monitors so they are constantly changing rather than being stuck displaying one color.

Is there any disadvantage of turning off the screensaver and just leaving your computer monitor(s) on all the time, if power consumption was not an issue?

Looking for some clarification on this thanks.

Screensavers to prevent burn in on CRT monitors aren't necessary on LCD monitors.  Occasionally an LCD monitor will act similar to a burn in but it is transient.  The onyy real real reason for them now IMHO is entertainment.

Actually, no, you don't need a screensaver on your computer. In reality, screensavers haven't been a necessity for many years now! Advances in display technology and the advent of energy-saver monitors have virtually eliminated the need for screensavers. Its not a good idea to keep the screen on for long time, as it could count the life of your LCD/LED; its better lock the session and power off the screen, when you are not near to your computer for sometime, end of the day completely shutdown the computer.

i hope the below article will give you an idea on screensaver

Yes, screen savers are still valid but their role is not as important as in the past. Now days most systems are being more power wise. Therefore monitors are in power save after 15-30 minutes of inactivity. So while the screen saver may start before the monitor enters power save it doesn't help very much. And with flat panel monitors being the norm, they recover from power save much faster then the older CRT type. However if you going to leave the monitor on all the time (i.e. no power save on the monitor), you should still configure a screen saver to avoid potential issues with permanent imaging or "burn-in".

Alright, so I can leave my blank desktop up for 12 hour sessions unlocked, since no one is going to access it, and it will not destroy the pixels in the monitor?



And before you ask why I dont just shut it off 1)i have things downloading and
                                                                          2)i have server apps (ftp,telnet) that need to be up

They shouldn't call them screen savers anymore. They should call them screen shows or something. I like to let my pictures do a slide show. I rarely turn my machine off. I just put it in standby.
