Turn off display

How do I turn off the main display when using external monitor or tv, or can you?
Thanks
Arthur

The way to turn the display off is by closing the lid on the MB. Here is a link to an Apple article on the topic:
http://docs.info.apple.com/article.html?artnum=86286
Notice the article mentions using an external keyboard or mouse. But that isn't absolutely necessary. For example, I often close the lid and then wake up the computer using a USB flash memory device. Then I can open the lid and use the built-in keyboard and trackpad and the internal display remains off.

Try Shift+control and the Eject key in the upper right of your keyboard.

Msi p45 platinum - freezes after power save turns off displays

Just put this computer together, everything is stock, no overclocking. Seems to run fine, played a few hours of modern warfare 2 with no issues.
I noticed It seems to freeze after the monitor gets turned off by the power save mode. I just tested this by setting it to turn off displays after 1 minute of inactivity, waited watched the monitor turn off, then I went to the move the mouse and the screen came back on but the cursor would not move. sometimes the screen will not even come back on.
I have turned the computer on, left the room while it was booting to eat breakfast or take a shower, came back the screen was still on but the computer was frozen. Window 7 login screen was up, but there were some graphic glitches. this has happened a couple of times.
If I manually put the computer to sleep it seems to come back properly.

I think it might be the video card or power supply. Was building two systems,
second system has identical motherboard, processor and ram,

Installed from same OS disc and same set of drivers. Second system seems to operate the powersave mode for the monitor correctly. Will have to do some testing switching videocards tonight.

Turn off display mirroring once and for all ?

Hi there,
I have a 13'' macbook pro, recently upgraded to Snow Leopard. Now every time I connect my external screen (a DELL E198WFP connected with the DVI output) the display starts in "mirroring" mode. I have to manually turn mirroring off every time. According to the documentation, MacOS is supposed to "remember" my settings the next time I connect the screen but it doesn't work. Previously I had a Macbook Air with Leopard and I had not this issue (the screen would start with mirroring turned off when I connect it). Is there any possibility to disable mirroring once and for all, as I never use this feature ? Thanks

Ok since you upgraded your system you might have a issue with your preference files for the displays. you need to Delete these two files reboot and Zap your PRAM. (Print this out)
#1. Delete these files:
/Library/Preferences/com.apple.windowserver and ~/Library/Preferences/ByHost/com.apple.windowserver"
#2. Turn off Computer
#3. Reset your PRAM by:
(From Apples instruction page)
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Turning off display

Is there a way to turn off the iBook display when my external VGA monitor is hooked up?

NO. The External Monitor only mirrors the display and when you turn of the iBook out goes the External (that is one reason why you can't close the lid on an iBook when using the External.... other than heat build up -- if the iBook lid is closed it sleeps and so does the External.
GOD Bless and Good Luck

Using Windows won't turn off display

When I am using Windows on my MacBook, I have set my Windows power options to turn off the monitor after 1 minute of not being used. The display never turns off. Is this a Windows or a MacBook problem? I tried setting it to 5mins, 10mins... Nothing works. I don't want to have my display on when I leave my desk.

IIRC, there are power management issues with running Windows on the MacBooks. Could be wrong, but I think I recall hearing this.
This would be up to Apple to fix via driver updates if it is indeed the case.

Turning off display in Mavericks

I have a retina MBP. I am used to hitting shift-control-power to *just* turn the display off and lock the computer -- *without* putting it to sleep -- when I leave my desk.
This still works in Mavericks 10.9, but it creates an annoying pop sound (Mac error sound effect) which never used to happen in 10.8 and previous versions.
I'm told that just hitting the power key for a second now does the same thing, but in my experience it doesn't. It sleeps the computer rather than just shutting off the display. I want the computer to still operate on the network and on full power.
Does anyone have a new key combination that just turns off the display but doesn't pop or beep?
I know I can dim the display brightness but (1) this doesn't turn off the pixels, just the backlight, and that's not what I'm looking for, and (2) this takes too long versus just a single action like shift-control-power.
Thanks.

Hi Fred,
I also organise by year, month, day/shoot. Within the day/shoot, everything is logically organised with RAW automatically downloaded into its own subfolder using DownloaderPro. I use Pixort to further split the RAW images into 4 subfolders depending on whether I want to work on the image immediately, later, or never. Developed images then go into the parent day/shoot folder for easy viewing. It sounds a bit complicated but everything is in the context of one shoot. I can very quickly identify and work with the high-payback images. I can very easily find and view the developed images using fast and simple tools like the file browser or FastStone.
Now LR is proving to be very useful at converting my RAW images, I'm impressed enough to invest some more time exploring it. But I've learned not to rely longer or even medium term on any one vendor or piece of software. And I'm certainly not going to change a proven approach simply because of an inflexible tool!
So come on Adobe, this can't be that difficult. How about adding the option so we can choose whether or not to view subfolder contents.
Cheers,
Mark

GT70 Turn off Display LED Backlight

Does anyone know how to turn off the DISPLAY LED Backlight when using an external monitor on a GT70 running 64bit windows 8?

You mean display all only on external?
Just righclick desktop and go to resolution setting. Set screen output only on external. You can do it in Intel graphic card settings too.
You can use Fn button on keyboard too. If i good rember FN + F2(just check images on buttons).
If you want to have 2 monitors but from some reasons you want to turn of screen on build in for some moment there is button to do next to power button 0 right side.

Turn off display (like an iPad/smartphone)

I have googled all night for this, and only found forum posts where people don't understand what the question is.
I'm looking for a way to make the power button on my helix do the same as a power button on an iPad or smartphone.
I want it to turn off the display and ignore any inputs from the touchscreen. Then touch the power button again and either have to unlock/swipe up or just continue where I was.
Yes, I could just lock the screen, but it would then still be on, thus using more power. I don't want to use sleep mode, since that would stop downloads/IM sessions/and so on.
Any suggestions?

Dont know about using the power button for this - but -
you can search the web for "monitor power off" scipts (Uses windows SendMessage with parameters specifying power off monitor), and create a shortcut for this script.
Then you could click this script, or set it with a hot-key to run it.
The only problem is that the screen will still be sensitive to touch, and will wake up on touch ot keyboard input.
** Did not try this myself.

Turn off display without shutting down?

I'm downloading a pretty large update (nearly 4GBs @ 190 hours estimated time) to my office computer (a Mac Pro w/ large display) and I would like to shut off the screen display, yet leave the computer on over the weekend. Reason being is that I am the only Mac in the entire building and well...lots of curious, lookie-loos like to salivate over my machine. Usually, I simply Log Out every night.

4GB should not be taking 190 hours to download. That is about the size of the 10.7 download, and if you get lucky that should be done in an hour.
You can turn off your display whenever you please, with impunity. If you have multiple displays, you may find all your open windows on the "last display standing" when you resume.

Are you referring to a MacBook Pro? I have the tower.
As far as the time to download...I noticed we were having connectivity/transmission issues before I left the office. Not sure why.
So Grant, are you saying that I can put the computer to sleep and it will still download the files? I have to go back into the office tomorrow so I'll check to see if transmission improved.
Thanks all!

Turn off display for Video Podcast...?

Howdy,
I use an iPhone 4 with the most recent software...
Is it possible to turn off the display while running a video podcast?
With earlier iPhones it worked fine, but the old method does not work, and I have been unable to find a method that will do this.
Thanks for any help,
A.C.

with the following command running in a commandprompt window you can turn your screen black untill you click or type something.
You can easily transform this in a script which runs every 10minutes in scheduled tasks
%systemroot%\system32\scrnsave.scr /s
GPO scheduled tasks
I've added a link to technet article about GPO and scheduled tasks
