Turning off monitor
I'm using my imac as a video server and have eyetv running. I'd like to turn the monitor off at times and I have tried using the shift option up arrow which works for about 5 minutes until something wakes up my imac and the screen turns on. I went to an apple genius and they suggested "kiosk mode" but I can't find any option for turning the screen off. It is a waste of power to run the screen al the time, not to mention light that is turning on and off all night which is a bother.
Is there any way to turn the screen off until I want to turn it back on?
I think there is an answer here: http://www.mactech.com/articles/mactech/Vol.19/19.12/KioskModeFeatures/index.htm l
But, it require some programming effort.
And, there is http://developer.apple.com/mac/library/technotes/tn2002/tn2062.html

[SOLVED] How to turn off monitor at CLI
Hi
I've been trying to find a way to turn off my monitor, but the solutions I've found were almost all for X environment.
The best hint I've got was add following lines to /etc/rc.local:
setterm -blank 1
setterm -powersave on
setterm -powerdown 1
With that, monitor was suppose to blank screen after 1 minute and, after another 1 minute, shutdown. But it only blanks and nothing more. Without the first line: "setterm -blank 1", it just don't do anything.
Does anybody has idea of what else should I try?
Thanks in advance.

Even with aliases, I would have to type von with monitor turned off.
I've done a script, witch is not a perfect solution, but works fine.
monitor_off:
#!/bin/bash
# Check if X is running or not, turn off monitor, #
# wait for a key press and turn it on again. #
grep_result_file=$PWD'/x_running'
# Check if X is running.
ps -e | grep -e "\bX\b" > $grep_result_file
ps -e | grep -e "\bxorg\b" >> $grep_result_file
ps -e | grep -e "\bxserver\b" >> $grep_result_file
## If you want to check result file, uncomment following lines.
#echo "===== $grep_result_file - begin ====="
#cat $grep_result_file
#echo "===== $grep_result_file - end ====="
if [ ! -s $grep_result_file ] || [[ $(tty) =~ tty ]] || [[ $(tty) =~ vc ]]; then
echo 'Detected X not runnig or you are at console...'
if [ $UID -ne 0 ]; then
echo 'You need super user privileges to run this script at console.'
echo 'Rerun as super user or start X and run from a terminal.'
exit 0
fi
turn_off='vbetool dpms off'
turn_on='vbetool dpms on'
else
echo 'Detected X running...'
turn_off='xset dpms force off'
fi
echo 'Turning off monitor...'
$turn_off
echo 'Waiting for a key press...'
read -n1 -s
echo 'Turning on monitor...'
$turn_on
rm $grep_result_file
echo 'Finished: monitor_off'
It checks if X is running or not because at X environment vbetool was a little slow, at least for me.
That's it!
I hope this could be useful for someone else.
Thank you for helping, guys.

P.S.: I'm setting this thread as solved, but any suggestion about the script is welcome. -
Bug: Windows 7 DLL call to turn off monitor message crashes LabVIEW 10.0f2
Hi,
I wanted to log this bug on the forum. I have already logged this with NI UK Support: CAR# 286873
I was trying to find a way to turn off a laptop lcd
monitor during measurements. I was trying to replicate this
http://codereflect.com/2009/04/03/how-to-programmatically-turn-onoff-your-monitor/
which uses windows messaging.
I found the attached Monitor-1.vi somewhere on the forum that seems to do the above.
However when I run the VI it crashes LabVIEW 10.f2 on Windows 7 32-bit.
cheers

ITunes disables Power Options- Turn Off Monitor
If I just run iTunes on my Windows XP PC my monitor no longer turns off after the "Control Panel->Power Options->Power Schemes->Turn off monitor" time period has expired. The monitor stays on contiuously. This issue exists even if I exit iTunes. I need to manually go into control panel and reset the "Turn off monitor" setting.
I suppose there might be a reason iTunes wants to disable this when it's executing but how about putting this energy saving setting back they way it found it when I exit iTunes.
Is there a way to do this?
Thanks,

GT70 BSOD or Stuck after Windows puts it to sleep mode of turns off monitor
Hi Everyone!
i have an issue (or 2) with my laptop.
both happens when:
1) whenever i put the laptop into sleep mode or either windows does so automatically (inactive period), - the laptop will go to sleep just fine.
2) windows turns off monitor after a period of inactivity. (sleep mode due to inactivity was disabled in this case)
in both the cases i mentions above, if i wake the computer within lets say 5 minutes, it'll turn on just fine.
but after a certain period of time passes it wont.
with the sleep mode, the computer will wake and will then produce a BSOD STOP error 0x4 and restart.
with monitor turned off it'll simply wont turn on, not responding to neither keyboard, mouse or power button. - i have to do a hard reboot
any ideas?
anything i can check?
note the laptop just came back from a warranty repair, so all parts have been tested and been found ok!
system specs:
MSI GT70-0ND
CPU: Intel Core i7-3630QM 2.4GHz (Intel GPU HD 4000 included)
Memory: 16GB DDR3
Storage: 750GB HDD 7200rpm
128GB SSD (Patriot Pyro SE) - OS installed on this.
GPU: 4GB NVIDIA Geforce GTX 675MX
OS: Windows 7 64bit
Thanks in Advance!!i dont think i have the same problem as in the other thread.
my bios:
my laptop doesnt restart when my screen is turned off and i try to wake it. it would simply wont wake up.
and my BSOD happens only after i wake the laptop from sleep mode and only if it been in sleep mode for a while. meaning i if i wake it up within a few mins of going to sleep it'll boot justfine. -
Turning off monitor detection?
Is there a way to turn of monitor auto-detection. I am using a kvm and have the a monitor hooked up as primary desktop on external dvi connector. Using iMac display as secondary monitor. Every time I use kvm to switch to another monitor the resolution gets reset and the anything i have on the secondary (main iMac) screen gets shifted over because primary sceens is resized to a lower resolution. How can i turn off autodetection or lock in the main screen resolution?
Hi calaban9
Welcome to Apple Discussions
Turn off Mirroring!
If you use Extended Desktop you can choose a resolution for each display, that should not change when the external is switched off.
http://docs.info.apple.com/article.html?artnum=303086
Resolutions
+When you connect the adapter to the computer, the screen may refresh momentarily as the computer prepares itself for the new video output. When the computer is mirroring video, it tries to synchronize the resolution of the built-in and external displays. If they can't be matched, the computer will change the resolution of both screens to the highest common resolution which may cause areas of the built-in display to be blacked out.+

Lock screen + turn off monitor
So I'm currently using slock to lock the screen, and It's working perfectly: I press the hotkey, the screen blanks and doesn't come back on until I've entered my password.
Is there any way to do exactly the same thing but with the screen turning off? The command "xset dpms force off" but it comes back on at the slightest touch and I'd like it to stay off until the password is entered.
thanks!Geissler wrote:2. The screen doesn't stay off until a password is entered, only until it detects user input, at which point you can only turn it back off by executing the command once more.
I use a simple script for slock and dpms handling:
( slock && xset dpms 0 0 60 ) &
xset dpms 0 0 2
xset dpms force off
This essentially turns off the monitor after 2s while running slock and restores the dpms timeout setting (60s) after slock terminates. -

HELP! Connecting shuffle to cradle turns off monitor
Hi, I've been having this intermittent problem that really starting to annoy. Sometimes while connecting my shuffle to the USB cradle my monitor will loose the video signal and go blank (looses video signal). Seems that the shuffle needs only to touch in male prong for the problem to happen. The only way to get the display working again is to reboot the PC.
Here's what I have: 2nd gen 1 gig silver shuffle, Vista (SP1), 4 gig ram, C2D 3.0 ghz, Asus EP35-DS3R motherboard, GeForce 7200GS GPU, Gateway 2200 connected via DVI
Oh, yes the problem happens no matter which USB input I use. I've updated all hardware and software, but I still have the problem.
Anyone have any suggestions or a similar problem?Thanks,
don't know why it'd matter if I had a warranty or not since the function
in question is apart of what I'm supposed to be getting w/ cost of computer.
Time to load the overpriced 1 ton computer into the car and demand they fix it at the apple store. This is absurd since I originally bought this computer for music creating and it's the most unreliable computer EVER as far as stability for music. My audiophile records for like 10 sec. before the sound cuts out, everytime, but of course that's not apple's fault.
Never buying apple again. This is straw that broke the camels back. Anyone wanna trade a pc for my G5?
Sorry for the venting but this is where I draw the line!
Thanks,

Turn off monitor on lid close doesn't work after first reboot
On a fresh installation ( running daemons hal fam alsa gdm bluetooth cups and others present after fresh install ) it worked perfectly. I was so happy, cause this is the last issue Im having.

Cannot turn off MBP monitor/display
I have a 15inch MBP running Boot Camp and XP. I am trying to use the "turn off monitor" setting in power options from the contol panel. However when the time is up it does not turn off the monitor...
Also when the "turn off monitor" feature is suppose to trigger, it disables my screensaver.
I don't want my computer to sleep, I just want to turn the monitor off. Right now I just dim the screen until it fades a little but I can still see my desktop screen so I know it is on.
Can anyone tell me how I can turn off the monitor?Support are now quoting Apple's engineers as saying it is now "expected behaviour" under Lion for the MBP's internal display to reactivate upon opening the lid, even if you want to use only your external display. A new version of the clamshell mode-related knowledgebase article (replacing HT3131) is due shortly confirming this.
This is despite:
- the obvious temperature-related benefits that were achievable (under Snow Leopard) by opening your MBP lid whilst continuing to output solely to, say, a 27" cinema display
- the waste of energy and inefficient use of graphics processing power in needlessly running two active screens (ie if running your MBP in clamshell mode would otherwise make it too hot and/or noisy)
- the negative longer-term impact on the battery and other components from running the MBP any hotter than it needs to be.
If you would like to have the previous behaviour restored, please lobby Apple to change how Lion handles clamshell mode. Options available to them include changing Lion's expected behaviour or adding a user-selectable option within System Preferences.

I'm doing a multicam edit in cs6 and the 5 camera angles I have are straining my system. I have two main angles and three kind of back up go pro angles that I don't need most of the time. But I don't want to get rid of them either. Is there a way to turn off monitoring some of the angles at times so that video will playback smoother? Then when I need the other angles, switch them back on when I want? The video is so choppy with all 5 angles monitoring at once that multicam editing is basically impossible. I'm editing on what's supposed to be a very fast system at work but it's not fast enough...Thanks!
I'm not aware of any way to do this. You might want to invest in a battery case if this is a problem for you; our users here all have them.
Please submit your feature request to Apple at this link: http://www.apple.com/feedback; I agree it's a good idea. -
Cannot wake up screen afer turned off by Power Saver on Tecra M5
Tecra M5; XP SP2.
Screen saver disabled.
Toshiba power saver set to turn off monitor after 10 minutes.
Once turned off, I cannot get monitor to turn back on.
I have tried various combinations of fn and function keys but to no avail.
Only solution seems to be to send to hibernate (power off button is set to hibernate).
Screen lights up to say hibernating and works fine after restart. Not a critical error but very irritatingHi,
For this problem exists a Microsoft Quickfix: http://support.microsoft.com/kb/917332

Display screen is turned off after timeout even when blanking disabled
After a recent update which among other things upgraded gnome to 3.10 my display blanking policy no longer behaves according to a configuration.
Currently it is being turned off (monitor says "no DVI signal" and switches off) after each 10 mins if idle time.
In Gnome's Power Settings I have 'Blank Screen' set to Never.
It used to work perfectly earlier, no blanking, but now it blanks not only when I'm idle, but even when watching some movie in VLC.
I am not sure if this has to do with Gnome update or some other system component is causing this.
Using nvidia driver.
Any hint or link to the topic with the workaround would be greatly appreciated.
I tried google and local forum search and found nothing on the topic
Last edited by dimsuz (2013-10-10 09:49:36)I just noticed myself this annoying issue and I do not use Gnome nor GDM.
The thing is after checking the xset settings with
xset q
I noticed that the DPMS settings for Standby, Suspend and Off were back to their default values (60/60/600) instead of the 0/0/0 as I am using
xset s off &
in my openbox autostart file to avoid the screen blanking.
The way I fixed it was to simply run
xset -dpms
being the DPMS featured as disabled when queried.
Afterwards I checked that the screen did not blank again and 1) logged out and 2) restarted checking both times that the DPMS were the ones expected (0/0/0).
Thus, so far, I have no issues with the screen blanking in a non Gnome environment (Openbox) anymore.

How do I turn off computer monitor when watching DVD movie on TV monitor?
I think this is really a Leopard question because it involves setting up 2 monitors in System Preferences within OSX. 1) I have a wide screen TV connected to my iMac (Intel White Late 2006) through the Mini-DVI port and a separate audio cable. This connection works fine. 2) The purpose of the TV screen is only to watch DVDs using the DVD player and iDVD in my iMac. 3) In System Preferences->Displays->Arrangement, both my computer monitor and the TV screen appear as separate monitors. I have the setting to mirror each other. With this setting, the DVD movie plays on both the iMac computer screen and on the TV screen. 4) FINALLY, MY QUESTION: When watching a DVD on the TV screen, I would like to turn off the monitor in my iMac so that the screen is dark (in sleep mode to save power, etc.); I want only the TV screen to display the movie. How do I turn off only the iMac screen? Thank you. Dale

That's impossible. It can only be done on a laptop but not on an iMac.
