I simply turn off the monitor when I'm not going to use my PC. Not sure? Read the piece @ A third of people believe screen savers cut PC energy use - Telegraph

They're not and never have been for saving power. That's why they're not called "energy savers." They're called "SCREEN savers" because if you leave the same image on a monitor for long enough, it will become "burned in" to the display, and there will always be a ghost of that image visible, even if there's a different image being displayed. It affects CRT monitors the most, although it can also affect LCD displays. Don't know if LED displays are susceptible.

Mine goes into sleep mode after ten minutes, sleep mode for whole computer after 15.

Old monitors that did not have these features or were displaying the same thing constantly as Swagger mentioned would get whatever was being displayed burned into the display. Find an old arcade game and the thing can be off and you can see it. I can remember this being an issue going back to the Atari's which had very little movement on the screen and kids would be playing them for days on end, "Combat" for example.

I remember those 3D pipes would actually consume more CPU power and heat.

An LED display for TV or a computer monitor is an LCD display. They get called an LED display because the back lighting for the displays uses white LED lights. A typical LCD display uses white florescent tubes for back lighting. So a modern LED would have the same problems with burn-in that a modern LCD display would have.

However the very large stadium "Jumbotron" LED displays are colored LED lights and have nothing to do with LCD technology.

Most of what I have read about LCDs say that the burn in is not the same as the old CRTs. They can get what is called transient image persistence or retention which is similar but can be made to go away by not using the display for a while.

I've only had one lCD with an image burn (a very old model), and it had some lines that matched dark portions of the desktop image on it. I was able to run a solid white screen saver on it continually for a few weeks, and it mostly went away.

Screen Savers Don't Save $, I'm curious as to why this is worth a post, who claimed they saved money?
