I believe that screen savers were originally used for CRTs so that an image would not be burned into the coatings on the CRT and also to provide access security.

Is a screen saver still required for LCD screens (aside from security concerns)?

The key word is..."originally."

I don't think anyone uses a screensaver these days for any reason other than self-entertainment.

Lots of good ideas from "the old days" have no value today, if not entertainment.

CRTs did suffer screen burn from static images after long periods. LCDs can experience image retention, but with the exception of a few abnormally susceptible models, it's a transient effect and is more of an irritation than harmful. Most people's screens change enough that it isn't a problem. If an LCD is on for long periods and displays the same application background all the time, a moving screen saver can still help avoid image retention by exercising the pixels.

Although it's not required, I agree with Platypus. It's a great measure to protect against image retention. I accidentally left my PC on overnight at work. When I came in the next day I had what one would think was burn-in on the screen from the background picture. I let it go for a few days hoping that it would wear off, but no dice. Fortunately we had warranty coverage and two extra monitors lying around that I could use to replace them.

So it's not a requirement, but it's a good idea nonetheless. At least you could set your power settings to turn off the monitor after a few hours or so to protect your screen, in case they're POS's like the one's I had were.

believe it or not some LCDs will still burn images, not as bad as the old CRTs, but it is still feasible. pixels do sometimes "stick" when left on to long. Its a rare occurance, especially in good quality LCDs, but I would. I always use one myself. even if I know it wont hurt anything, I still use my screen saver, most of the windows default screensavers do not hurt the performance of your PC, they do look pretty, and they can't hurt anything so I would go ahead and use them. :D

Personally, I have my pc set to shut my monitor off after 30 minutes of no use, I figure that way maybe my backlight will last longer.
