miniDisplay to HDMI : How to turn off the Dual Monitor output when the adapter is attached and the TV is off ? And will keeping the adapter connected even if it is not in use, cause damage to the adapter ?

I have my external monitor/tv setup of the left. If I leave the adapter attached with the TV off, I am still able to cross the border/boundry of my MBP screen ! As instead of detecting a TV, the MBP is detecting the adapter as a screen. I do not want to damage my thunderbolt/miniDisplay port by plugging and unpluggin the unit each and every time.

Hi,
that depends on the release u use ... For release <SPS15 u can unasighn the notification method via the TA rz21.
If u use CEN monitoring its easy to unassign --> just goto TA RZ21 --> start: Technical Infrstructure --> configure central systems --> assign central autoreactions
The new mask gives u the possibility in the bottom frame to unassign methods.
If u use lacal monitoring (that u will see when u start the assign central autoreaction and no method where assigned) --> than it will be more difficult u have to unassign every MTE from the auto react methode ... Or u modify the the auto react methode

When mirroring - can I turn off the monitor on my Mac...?

I just set up my MacBook Pro with my AppleTV and everything is working nicely. However, It would be even better if I could get my computer monitor to turn off while I'm viewing on my TV.
Is this possible?

Actually, the answer is YES!
Thought it best to post here again because I discovered that while Mirroring, turning off the monitor on my MacBook Pro is possible (despite a few replies here that it cannot be done). Its super easy to do, just dim the monitor until it goes completely dark, and continue to use your computer as it is displayed on the TV. The trick is not to close the monitor down, that will put the computer to sleep.
While I was hoping I could also achieve the same result while my MacBook is connected to my Cinema display, it seems the dimming capability on the Cinema display is limited to getting very dim, but not turning off completely.
I'll keep researching this some more and if I have any more updates I will post back to share -- hopefully there are other users who will find this info helpful.
For now, I will be using my TV as my primary display while my MacBook Pro's monitor is turned off.

Do you have backups of all the data on the startup drive? If not, do nothing else until you've backed up that data, if you still can.

How can I turn off the monitor but not the computer on my touchsmart 310..

I leave my computer on at night to keep wireless network going, but I want to turn off just the monitor. All of the advice I've seen is to turn off the touchscreen feature -not the monitor itself. Thank you.

You can set the timing for the display to turn off.
Try this:
Click:
Start.
Control Panel.
Hardware and Sound.
Power Options.
On the left bar you'll find Choose when to turn off the display.
At Turn off the display: there is a drop dowm menu to choose the number of minutes before the display turns off. Make your selection.
Try that and see if it works for you.
I hope this is what you were looking for,

This question was solved.

Hi,
Power Button Lockout is displayed.
The monitor's Power Button Lockout function is enabled.
Press and hold the Power button for 10 seconds to unlock the Power button function.
If the above doesn't work then try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up.

Can I turn off the monitor for Mac Mini and use it as a music server?

I am in the process of upgrading my PC most likely to a Mac product. With the non-server version of Mac OS X, can I turn off the monitor connected to a Mac Mini and use it as a streaming server? Or I have to get the server version of OS X to do that?

I plan to run Logitech Media Server on the Mac to stream music to players. Each player interacts with the Logitech Media Server to select songs to stream. When I turn on a player, it will wake up the computer from the sleep mode.
Currently, this Logitech Media Server runs on a Windows Vista machine and it will keep the PC from entering sleep mode while playing the songs. After I play the last song, the PC will start the idle count down and then enter into sleep mode.
Do you see any problem with my intended use of a Mac Mini?

How to turn off the Monitor???

Hey friends!
Is it possible to turn the Monitor (Display Device) ON and OFF from a java application???
Thanks a lot!

Hi! This is completely Windows-specific, and I found it on a website, so I don't take credit for it. Hopefully you do know how to use JNI, so here's the C code you could try out (no I haven't tried it yet).
JNIEXPORT void JNICALL Java_JNative_turnOffMonitor (JNIEnv *env, jclass cls)
SendMessage (HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, 2);
}2 turns off the monitor, HWND_BROADCAST sends the message to all top-level windows, 1 sets the monitor to low power and -1 switches the monitor back on. Please use at own risk, and you'll probably want to have some more error handling in your code if you do plan to use it. You will need to include windows.h and user32.lib (unless you are dynamically linking) for the code to compile.
Hope it helps.
Cheers
P.S. Here's the website I found it in (note, the code's in Delphi, so I just took the API calls, and modified the first parameter to HWND_BROADCAST). http://chiragdalal.tripod.com/howto/monitor_on_off.html

T43 & "Preparing to turn off the monitor"

A recently got a second-hand T43 (I will avoid the current shallowscreen laptops as long as I can!), and one thing that bugs me is that Fn+F3 "turn off screen" seldom works (Windows XP SP3). Usually I just get the dialog saying "Preparing to turn off the monitor", but nothing happens after that. I read somewhere that Windows Media Player can cause this when running, but it is not running. And why should it matter anyway? Is there any way to force the screen to be turned off despite running programs?
Also, it would be nice if this action locked the screen, or if it was available after locking the screen. Is this possible in any way?

I have an Apple monitor model A1316 is using for Windows computer, but I could not adjust the brightness. The monitor is not bright enough when I turned off the lights in my room.

Have you plugged the USB cable into the computer also as the brightness is controlled over USB. If this does not work, you would need the Apple Display Driver for the version of Windows that you are using. The display driver is part of BootCamp software that you may be able to find online

S1 Yoga - How to turn off the built-in display/monitor?

Hi,
Trying to find a way/hotkey to turn off the built-in display whilst I'm connected to another external monitor with the Thinkpad S1 Yoga model. Do you guys know how to do it?
I could even remap any of the default hotkeys if someone knows how to do that as well, as the defaults are not too useful for me...
Thank you!!
Solved!

How can i delete my icloud account but not the password to turn off the find my phone

how can i delete my icloud account but not the password to turn off the find my phone setting

Make sure you are signed into iMessage and FaceTime with your current ID. If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.) Now go to Settings>iCloud, turn off Find My iPad and enter your current password when prompted (even though it prompts you for the password for your old ID). Then save any photo stream photos that you wish to keep to your camera roll (unless using iCloud Photo Library). When finished go to Settings>iCloud, tap Sign Out and choose Delete from My iPad when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your device).
