Best way to protect Laptop display when not in use

Hello everyone.

A quick question please. Sometimes I leave my Latitude switched on the whole night to do some work calculations while I'm asleep.

What's the best way to protect the machine's display?

a. Function D to turn off the display + Windows' Blank screensaver
b. Reduce the brightness to its very minimum + Windows' Blank screensaver
c. Change Power options to "Do Nothing when I close lid" and I close the lid

"b" is what I do on my old D520 and never had display issues but I prefer to read what you guys believe is better.

Thank you.

 

I'd say, don't worry about using the "Windows blank" screen saver or turning the brightness down. Just configure Windows to turn off the display completely when the machine is not in use (for 10 minutes or so?). It's in the power options, separate from the screen saver.

 

+1 This works fine IMO

 

I set my power option to turn the display off after X minutes, usually 20; Because I've wondered off and probably taken on another non-computing task.
I also don't set the screensaver, that is, I set it to none. And in the evening when quitting either close the lid (set what closing the lid does option to nothing) and leave it on (the display should turn off), or set the power button to sleep and sleep it overnight.
For running computing tasks overnight (leaving it running) then just close the lid. Screensavers require resources and blank uses some lighting still.

Since I don't use the screensaver the workstation can't/won't lock itself automatically after idle period.
It is said that this can be accomplished using a task: rundll32.exe user32.dll, LockWorkStation
Path %windir%\System32

 

This when I do backup or virus scan. And the above.

 

Cheers guys, I completely forgot about the turn off monitor option in the power options

 

Sometimes it doesn't always work, and there are situations that could cause the monitor to turn on or stay on, so you'll be better off just closing the lid.

 

I don't get it, how any of those option (turn off, screensaver, etc) "protect" the display?

 

Leaving static content on an LCD for hours will cause burn-in. You can see this on displays that show restaurant menus, airport departure/arrival information, etc.

 

A poor choice of words? Perhaps OP would like to clarify exactly what he means by "protect"?

An inaccurate description since by design (the lack of a scanning beam) an LCD is immune to burn-in. At least in the conventional sense.

Perhaps there is an equivalent phenomenon that manifest similarly, but the term "bun-in" is misleading. Especially without further clarification.
