Turning Mirror Display Off

Turned Mirror Display on for presentation yesterday to do a presentation on a projector. Now does not give option in Display preferences to turn off. Icons on desktop are moving and changing sizes. How do I turn off. Command F7 does not work. Whi is it not an option to turn off in Display Preferences any more.
Any info. would help.
Thanks.

One other thought. The mac detects how many displays you have automatically. You don't have to "turn off" the second display if it's not present.
When you said the icons are moving and changing sizes, Does that mean that when you move the cursor to the dock that the icons get larger as you move across them?
If so, you can turn this off in System Preferences -> Dock. Just uncheck the "magnification" box.

Is there anyway to turn thunderbolt display off while is pluged in?

I have a 27 in imac and a 27 thunderbolt display and i want to turn the thunderbolt off, but i dont want to un-plug it. is there anyway to turn it off without unpluging it???

There's no on/off switch so your options are either standby from the setting menu or main menu using the remote.
, or pulling the power cord.
The device must be designed to be turned off by pulling the plug as there's no shutdown sequence but like many it doesn't fell ideal doing that.
Standby is not a full standby mode and there are still background processes:

Consequently power consumptiuon is higher than you might expect.

Stream7 - bluetooth audio streaming goes off when i turn the display off!

I have a hp stream 7 that is connected via bluetooth to my loudspeakers.
Everything is fine until the display turns off or i press the power butten to turn off the display.
When i turn on the display(press power button) the sound starts and play normally.
I can't find any option to turn off this behaviour in w8.1. Can you help?

The microsoft music player that is on the tiles metro section of windows supports music playback when the connected standby is activated. Unfortunatly if you are looking to go any further than this you will need to change over all your power control settings to that of a laptop.
I instructed another user of it in this post here, http://h30434.www3.hp.com/t5/Windows-Tablets/Stream-7-Can-t-Turn-off-screen-without-putting-tablet-i...

Turning imac display off without putting it to sleep questions?

I like to leave my iMac on overnight but I don't want to put it to sleep COMPLETELY. Just to turn off the display. I heard you press control-shift-eject or do a hot spot on screensaver on system pref. But my question is, would it hurt the iMac in the long run for leaving it on overnight so much or it's made to last like that?
I talked to an apple specialist at the local apple store and he said these aluminum imacs are made to last even if you keep them on overnight? But would it overheat over the years? or I shouldn't worry so much. Sorry this is my first iMac. I have so many questions about it.

So it will not overheat no matter what?
If you are playing some 3D action game, or having the computer encode video for one hour straight, it may start to heat up. But then, the fans should kick up to a faster speed (you'll actually hear them), to keep the temp within the acceptable range. If the iMac is just sitting there, waiting for you to do something, it will not overheat. Now... If there is dust blocking airflow, or the Mac has some hardware issue that prevents the fans from running properly, then it is possible for a Mac to overheat, which may cause it to shut down unexpectedly or give you something called a +kernel panic+ (which is basically a system-level crash).
When a computer is running, for most users, it spends most of its time waiting for you to do something. If you are doing something simple like writing an email or web browsing, 90% of the time, it is waiting for you to do the next thing. If you have it doing something like ripping a music CD, during that time, it is working hard to finish as quickly as possible. But since most people do not rip CDs all day, most of the time, the Mac is coasting along, not working very hard. So, there is not much stress on the hardware most of the time it is turned on.
But if you shut down every night and start up every morning, one stressful time for the hardware is at startup. This is because all the components, such as the hard drive spinning up, display turning on, and the rest of the Mac are being powered up, happens at the same time. Waking from sleep is a similar process, and although it is not as bad as a full startup, it may happen much more frequently if the user is sleeping the Mac and waking it up frequently. That's why I suggested using sleep at the end of the day, to save power compared to keeping it ON, but once you have the Mac running at the start of the day, don't have it sleeping and waking numerous times throughout the day; just let it run until you are done for the day, then use sleep until the next day.

How can I turn my Macbook Pro display off instantly?

Hello.
I love having my laptop connected to my TV via HDMI cable to watch TV shows. But I dont like putting it in Clamshell mode because I have a VLC Remote app that lets me put the next film on instantly without touching the laptop.
I like to have the laptop display fully off / black so that i'm not see two images (TV and Laptop), so what I do is hold the brightness key down to turn off the display.
Does anyone know of a menu bar app, or a command to turn the display off instantly with a single click?
Thank You

No eject key on new Macbook Pros...
I guess it depends on you Macbook Pro. My 15" Macbook Pro (2011) has the eject key to the right of the F12 key far upper right corner of the keyboard.
My wife's 13" Macbook Pro Retina (2013) has a power button there, HOWEVER, Control-Shift-Power does exactly the same as Control-Shift-Eject. That is to say Control-Shift-Power will turn off the screen.
So assuming you have a power button, use
Control-Shift-Power
NOTE: my older 2011 Macbook Pro has a power button in the case, not part of the keyboard, AND Control-Shift-Power also works on my older Macbook Pro to turn off the screen.

Turn display off without turning computer off

Ok so this is driving me completely nuts. I know Steve Jobs hates buttons which is why we don't get a power on/off button on the display so how the **** do I just turn the display off completely? The only shortcut I found was to hit ShiftOptionEject which turns the display off but doesnt actually power it off, and if the computer tries to do something in the middle of the night (start a backup/start an EyeTV recording the display turns back on!!). This is driving me nuts. I'm almost at the point of selling this **** thing and buying a display with a ******* power on/off switch.

Yes you can sleep the display without sleeping the iMac.
The Apple remote is for operating multimedia applications with a Mac, and it can sleep and awaken a Mac, but not just the display.
There is some software that can extend the usefulness of the Apple Remote, such as Remote Buddy.

IMac always auto detects for external monitors after waking from sleep or from display off

I've got a Dell 24" monitor (2408WFP) plugged into my mid 2011 iMac via DVI cord and thunderbolt attachment. Things work fine.
When I need to leave my computer, I usually turn the displays off using the shortcut keys: CTRL + SHIFT + EJECT
This works perfectly and both displays go black. However, when I return to my computer and reactivate the iMac, the iMac display will turn blue as if I have just plugged in a new monitor even the external monitor is still plugged in. It usually flashes blue twice before displaying the password prompt. I can usually just log back in as normal. I've never had this happen before using Snow Leopard. It's annoying but strange.
However, even more strange is that sometimes when returning to the desktop, the iMac will do the auto detect display thing and then when I log back in, the external display just shows static as if there is no signal. I've checked the cable a million times and everything is as tight as tight can be and both ends are plugged in properly. Unplugging the displayport adapter from the iMac and then reattaching it restores the desktop on the secondary display although sometimes, it results in the secondary display showing a gray background picture instead of my normal picture. Replugging the secondary display seems to fix that too although sometimes it doesn't.
Why is this happening?
- Problem with the adapter?
- Problem with the DVI cable I'm using?
- Compatibility issues with my external monitor?
I need to stress the point that this has never happened before with Snow Leopard.
If I am the only one experiencing this then I suppose it may be an issue with the iMac or adapter or even the cable. But if anyone else can shed light on this problem, I'd really appreciate it.

Hi Micheal,
I've been experiencing the exact same issue with my new iMac I just bought. I bought it refurb so I wasn't sure if it was a defect with the hardware or not. Since I'm not the only one I will asume it's not for now.
Setup:
- iMac 27-inch 3.4GHz (Release May 2011)
- Dell 2709W external monitor
- Hooked in with mini display port to DVI adapter
- Lion 10.7.3 all up to date to this day
From what I've been able to gather the issue presents itself only when my Dell 2709W enters "Power Save Mode" after I do CTRL + SHIFT + EJECT or when the diplays simply goes to sleep by themselves.
Although if I hit that combination and the displays goes to sleep but I don't wait long enough for my Dell monitor to actually "Power Save Mode" (wait like 2 sec) then touch the keyboard then the 2 displays (iMac and Dell) resumes from sleep without the issue presenting itself.
I'm tempted to buy the mini-display port to HDMI just to see if the issue is still present with that adapter. If I do I'll update my post with the outcome.
If anyone else has any info to help with this issue it would be greatly appreciated. It's very annoying when you resume from sleep and you find all of your windows that where opened on the external display before sleep squeezed into your main display (iMac).
Thanks!

Effect Screensaver, Sleep and Display off have on Encoding processes?

I'm trying to understand the effect screensaver, sleep and turning display off have on applications such as burning a dvd, ripping a home dvd, encoding processes, etc.
I'm assuming sleep will abort those sorts of processes?
What about screensaver and display options?
Sometimes I have to run certain encoding or converting processes for a while and I'd rather conserve energy, instead of turning the settings to Never for all.

Correct, it seems like ANY attempt to turn the display off is putting the tablet into its low powered conncted standby mode. What is it you are doing that is effected by this?
I havn't tried this, but using the enable hibernation method , that is going to network adapter properties and turning OFF the "wake on" in the advanced tab which seems to disable the connected standby, the tablet may resume working like a regular laptop complete with seperate sleep and screen off modes.
Just keep in mind this disables connected standby for good, you will need to hybernate or shut down to turn the tablet off.

Is it possible to turn off imac display while mirrored display plays video?

I've set up a new 21.5" imac for my parents use in their living room and have connected their 52" lcd tv to the imac as a mirrored display.
One issue that i can't find a solution to is to find a way to turn OFF the imac display when they're watching content on the lcd tv. If they want to watch a film from the imac out to the LCD TV, they want to dim the lights and watch it, but the imac display being on in the dark room is distracting.
Is their any way (3rd party software??) to turn off the imac display while still being able to have the mirrored display running?

You should actually NOT use mirroring, although it would work OK on the 21.5-inch iMac because the screen resolution is identical to 1080p HDTV.
In System Preferences Displays pane Arrangement tab, turn mirroring OFF. This makes the HDTV screen extend the iMac's Desktop. In the diagram on that pane, it shows how the two screen arranged. The edge where they touch is where you can move your mouse cursor from one screen to the other. You can move the two screen around in the diagram, to match how the iMac and HDTV are located in the real world.
In System Preferences Displays pane Display tab, there will be a window for each screen. The 21.5-inch iMac's screen should be set to 1920x1080. The HDTV's screen should be set to 1920x1080 also, if it is a "1080p" HDTV.
To watch video content on the HDTV, first show the video playing in a window. Drag the window to the HDTV screen so that it is completely on that screen. Give the full screen command (usually Command-F). The video will play in full screen mode on the HDTV screen. In most video playing applications, such as DVD Player, QuickTime Player, iTunes, etc., the other screen (the iMac's screen in this case) will go black. It's not OFF, but it will display black.
Note: Some video playing apps have a preference setting for which screen gets the full screen. When playing video content in a browser window (such as YouTube or Hulu), when you go to full screen mode by clicking the +full screen+ button, the other screen will not go black.
As far as I know, there is no way to turn off the iMac display, even with mirroring turned OFF.

IMac 7,1 turning internal screen off while watching a movie via output (second display), possible?

iMac 7,1 turning internal screen off while watching a movie via output (second display), is it possible with Lion?

Actually, Plex does the best job by placing a black background to the internal iMac screen it's called Blanking.
However that does not turn off the backlit which is very bright on the iMac 24" also the internal screen will draw more power that way. As you probably know running bootcamp you can turn off the internal screen while watching a movie on the external. This isn't a hardware limitation, I hope Lion has this feature.

How to turn display off msi 110w

Hello,
I use both android and ios devices and when clicking the power button, the display turns off to allow for background tasks to continue running.
Can this be done on the 110w? I'd like the screen off when listening to music or running updates.
Currently when i press the power button, nothing happens, but when i hold it for a few seconds, the tablet sleeps.
Thanks in advance.

I haven't found a way to do this.
You could set the screen time out to something pretty low so that it blanks if not used after a short time.
I considered that, but found it became quite annoying when I needed the screen to stay on.
I had a program which turned the lcd display off when run, but i'd like the power button to perform that action, not an app.

When I open Numbers it displays every spreadsheet I've ever worked on. I have 100 windows displaying spreadsheets. What am I doing wrong? How to I turn this feature off?

When I open Numbers it displays every spreadsheet I have evr worked on! The screen fills with 100 windows showing different spreadsheets. How do I turn this feature off?

As Jerry said, if you close all documents before quitting Numbers or Pages, you won't have them reopening when you launch the app again. If you don't want to have to close everything first try Lion Tweaks or the latest version of TinkerTool. Both have the option to turn off the resume feature for individual applications.
