Best way to protect Laptop display when not in use

When I read screensaver and such, it lead me to think about burn in, but similar to krane, I thought it is a non issue for some years already?

 

Well, maybe it's just myself going back to the old days of CRTs and indeed "protect" as in to avoid burn-in. But yes, funnily enough, as I think about it, I'm not even sure what's there to protect. My old D520 has been going strong in terms of display for 7 straight years!

Maybe I should go back to Johnny Castaway

 

Maybe it would be more accurate to call it image persistence, but regardless what it's called, LCDs can be damaged by static content.

In the same sense, people don't usually bring firewood to housewarming parties anymore, but they're still called that. LCDs aren't susceptible to burn-in by the original CRT context, but the term has taken on a more general meaning and can refer to any screen that was damaged by static content.

It's definately still around...I've seen it on plenty of airport terminal LCDs. Screensavers don't serve much purpose anymore because they have largely been replaced by aggressive power saving policies, which have the same effect and also save power.

You'll still be prolonging the life of the LCD and its backlight. If anything, you'll protect yourself from dead pixels.

 

This can happen. Closing the Lid removes all doubt and concern.

 

Does it damage the monitor if you set the computer to do nothing when you close the lid, but also have the screen saver set to blank or none with password protect?

I often need to leave the laptop unattended so need to be able to password protect it too. I had never thought it may damage the monitor.

Thanks.

 

If the lid switch sensor is working, it will switch off the screen when the lid is almost closed. The "do nothing" setting in Power Options will not override this.

 

slimpower, this is correct. The "do nothing" for closing the lid setting simply precludes any sleep state options. If you want to lock the computer use Win + L keys when leaving it. The display will still turn off according to the setting for when to "turn off the display after" elapsed idle time.

 

Thanks Robin24k and rcb.to.ca

 

I wanted to add since I didn't address the question fully.

If you want to walk away from the system and have it automatically lock itself after an elapsed idle time then you have only one other choice besides setting the "screensaver to none" and "password protect on resume". The alternative would be to create a windows scheduled task: rundll32.exe user32.dll, LockWorkStation

--------------

You can put this in a notepad file and name it: LockWorkstation.bat

%windir%\System32\rundll32.exe user32.dll, LockWorkStation

Execute it and the system locks the same as keying Win + L

--------------

You'll notice the command window will open and close. There is no way to suppress it.

Setting direct scheduled task parameters will preclude this behavior.

 

I don't like leaving a machine running with the lid closed since it reduces the cooling ability which could be an issue if the machine is working hard. I leave it somewhere it won't get knocked with the lid angled to about 30 degrees instead.
