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

MiniDisplay to HDMI : How to turn off the Dual Monitor output when..

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

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?

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?

Unfortunately there is no on off switch.
The best you can do is sleep the display or

I don’t know what unplugging it will do/cause.
You can try it.

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.
