How to switch off laptop screen when you connect external LCD?

Hello, being new to Mac I'd like to ask if it is possible to completely switch off the laptop screen when you connect an external LCD screen and use it as your main desktop. My MacBook Pro does that automatically when I launch a full screen game, say World of Warcraft, but I would like to be able to do it manually.

If you have it connected to a keyboard and mouse, you just shut the lid and use it that way. Of course, I'd be curious why you wouldn't want to use the screen. Having two screens can be extremely useful. The only problem with it is that then you may miss it when you are away from your second screen!

i just want to know how to trurn off the screen for save energy and protect the screen,someone tell me please! thanks a lot !

If you are ready to switch off, put to standby/sleep mode you laptop by pressing alt-F3-F4 or through menu, then I recommend you set in power options "when I close the lid-do nothing". In that case closing the lid will switch off the screen for downloading time.

When we connect external LCD display colors get distorted, a NEW problem

We have used an Envision external LCD monitor with this iBook for one year with no problems, and now suddenly when we connect it to the iBook the colors are all way distorted (no red, or all blue), on both the iBook display and on the external monotor. When we disconnect the external monitor the colors on the iBook display return to normal. HELP!!!! What could be causing this?
Thank you!

Changing the adaptor cable solved the problem.

How to switch off primary screen

Hi,
I need to turn off me primary screen on a 2009 27 in imac, how can I do it wile using a second monitor ?
thanks

Hey Joe
It's a little tricky, but it can be done!
1. Switch to Extended Desktop.
2. Then in *Displays > Preferences > Arrangement* move the Menu bar to the connected monitor/projector.
3. Then with Shades you can dim either the iMac display or the connected monitor/projector to any level you like.
http://www.versiontracker.com/dyn/moreinfo/macosx/31515
Shades tips:
1. Shades will only allow you to dim the displays independently in Extended Desktop Mode!
2. In the Shades Preferences you'll have to check the box for *Constrain to its own screen* in both the iMac and NTSC/Pal tabs.
3. Now you should see 2 Shades Icons on the menu bar 1 for each of the displays.
4. Note the Hot Keys and/or set the Min brightness slightly up from 0% at first so you don't get lost in the dark.

How to turn off laptop screen....

when my PB is connected to my Plasma and how do I get the sound through my amp/speakers?
Help appreciated.
Cheers

Could you just put the brightness to the lowest setting, which will turn off the backlight?
As for sound, you can use a 1/8" mini plug to RCA cable to connect your PowerBook to your amp/speakers.
If you have the last PB models with optical audio output and your reciever has optical audio input, you could get a optical audio cable to connect your PB.

How to blank laptop screen when using external monitor/

Hi there
I need some help with figuring out how to configure my xorg.conf for my Arch Linux 64 bit installation on a HP Pavilion dv 5000 laptop so that I can automatically blank my laptop screen when using an external monitor. I have Arch Linux installed along with Ubuntu Feisty. In Ubuntu my external monitor (Viewsonic 1912WB) was not detected at the time of installation but with the native 1280X800 resolution that is good for the laptop takes effect for the external monitor automatically when the external monitor is plugged in. The laptop monitor goes blank when the external monitor is plugged in.
In my Arch Linux installation I have not been able to configure a dual head configuration using the ATI Radeon drivers (fglrx). I have the native 1280X800 resolution set up for the laptop monitor and this resolution takes effect for the external monitor also. However the laptop monitor also continues to function when the external monitor is plugged in. I would like to blank the laptop monitor when using the external monitor.
I am attaching my Arch Linux xorg.conf and the Ubuntu xorg.conf below. Thanks for anyone who can help, I am having a lot of difficulty in figuring out how to set up xorg.conf among all the things that I have had to learn so far in Linux and I am a relative newcomer to the whole thing. I have tried to compare the two xorg.conf files and edit my Arch xorg.conf in accordance with the Ubuntu one but it did not work and I keep getting errors!
I am using XFCE as my Desktop environment.

Xrandr 1.2 provides means for this. But today the only supported configuration is xorg-server-1.3 + xf86-video-intel-2.0. So for Radeon you'll have to wait for drivers that support Randr 1.2.
On my laptop (Thinkpad x60s) that would be:
xrandr --output VGA --auto
xrandr --output LVDS --off

No you can not do this; you can only turn off the Backlight.

How to switch off internal macbook screen when using external monitor(s)

as far as i observed, adding external displays ( running different screens on them, not mirroring) to a macbook pro increases the gpu workload and with that comes temperature rise in the laptop and increase in ventilator noise - and probably increased hardware aging and risk of component faillure due to high temperature inside the laptop.
simply try connecting two external 27" screens and open some flash video on both of them. then run a temperature monitoring software and watch temps rise, compared to running same flash videos / demanding tasks only on one connected external screen or only on the laptop screen with no external monitor connected.
especially in mavericks, due to its increased background routines, such a set-up appears ever the more taxing, then again who does not love apple`s nice adds showing laptops with two 27” screens connected to it and the workspace vision they invoke....
i have seen temps around 100° to 102° celsius on a 13" macbook pro 2012 edition, which i would expect is territory where the cpu / gpu temp safety switches will trigger system shutdown any time soon ( hardware status before verified as fully in order by apple service and default osx installation)
imagine your anti-virus software starting some realtime content screening while runnign some demanding tasks already and the system shuts down easily (all such situation observed in reality)
(would be interesting to see how a retina display macbook fares with 2 external monitors running demanding tasks, considering the retina display already increased taxing for the gpu - any experience from users of such a setup would be very much appreciated as it will provide critical purchase decision intelligence for all of us envisioning a retina-book and two big screens adoring our desks...)
turning down the macbook`s built-in screen`s backlight may reduce power consumption but i have not seen any evidence that it switches off the gpu-to-screen feed and respective gpu load - it certainly did not prevent gpu, cpu, board, etc temps to rise to borderline levels.
so the key question here is, how to switch off the macbook pro`s built-in screen in order to avoid gpu cycles being wasted on that screen ( and the resulting heat developments) when working with big external screen(s) connected to the laptop ?

this thread talks about running several monitors as advertised by apple and running demanding task on them.
with the lid open, the keyboard offers a very efficiant heat escape vector, which is blocked when the lid is closed - this is a basic and commonsense insulation effect. this thread also mentions the use of temperature monitoring software and thus a repeatable test setup. the temps recorded were also mentioned. they rose when the lid was closed, the running task remaining unchanged. as far as i could track down the cpus in discussion will shut down around the 105 degree celsius range. i observed system shut downs when the system approached 103° celsius. not to mention that the fans will run loud well before that.
again this is on hardware checked and ok-ed by apple service.
the question still welcoming an expert answer: is there any way to switch off the built-in macbook monitor while the lid is open ?

As I already said in my first reply post, you cannot turn off the iMac's display. The best you can do is display black, which many applications that have a +full screen+ mode will do, if the full screen mode is on the other display.
Alternately, you can move the menu bar (along with Dock and disk icons) from the iMac's screen to the second display. This is done in System Preferences Displays pane Arrangement tab, by dragging the white bar in the diagram from one screen to the other. Once the menu bar and other features are on the second display, the only thing showing on the iMac's display should be the Desktop background. If you pick a Desktop background that is all black, your iMac's display will be showing a black screen (although it will still not be turned off).

Welcome to the Apple Community.
You can't. Mirroring is just what it says, it mirrors exactly what is on your computer screen, if there is nothing on your computer screen, that's what you will see on your TV screen.
