I have a Mid 2011 27-inch iMac running OS X 10.8.4 with the AMD Radeon HD 6970M graphics card and two external monitors.  I don't know if it's related but after installing the 2013-003 security update that came out on July 2, 2013, my iMac's display randomly shuts off.  Up until yesterday (July 3, 2013, which is when I installed the security update), there were no problems. 

 

When the display turns off, sometimes putting the computer to sleep and waking it back up will fix the problem.  Sometimes restarting the computer will fix the problem.  Sometimes, I have to shut if off, unplug the Thunderbolt cables from the iMac, turn the iMac on, then plug in the Thunderbolt cables again. 

 

The frustrating part is that none of these solutions work consistently.  I'll be in the middle of doing something and the display just turns off so I have to spend 5 minutes trying various things just to get the built-in display working.

 

I will paste the log from Console below.  As far as I can tell, 12:51PM is when the display just turned off, and 1:07PM is when the display just turned back on.  I'm not sure why though.  If anyone can help, that would be greatly appreciated.  Thank you!!

  • 1. Re: iMac display turning off randomly with external monitors
    BDAqua Level 10 Level 10 (116,470 points)

    Hmmm, quite curious, I slightly suspect some power issue, possibly USB?

     

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

     

    If that doesn't help Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

     

    Does it work in the new account?

  • 2. Re: iMac display turning off randomly with external monitors
    mrbofus Level 1 Level 1 (5 points)

    Nope, those steps didn't help.  Today, it's been randomly turning off but then turning back on five seconds later.  Which I guess is better than before, since I don't have to keep rearranging my windows anymore.

     

    But, it's still pretty darn annoying.  And I'm hoping that it was something in the 2013-003 security update, because I had zero problems before then, and it seems like it would be far too much of a coincidence for this issue to start happening right after I installed that update.

     

    I submitted a bug report to Apple, but unsurprisingly, haven't heard back from them at all.

  • 3. Re: iMac display turning off randomly with external monitors
    BDAqua Level 10 Level 10 (116,470 points)

    Sorry, I'm at a loss not having the same problem or equipment.

  • 4. Re: iMac display turning off randomly with external monitors
    mrbofus Level 1 Level 1 (5 points)

    Yeah, I figured this was sort of a one-off issue; I haven't been able to find any reports of anything even remotely resembling what I'm experiencing. 

     

    Thanks for the effort though!  Much appreciated. 

  • 5. Re: iMac display turning off randomly with external monitors
    BDAqua Level 10 Level 10 (116,470 points)

    There is a fairly similar one here... with no cure yet...

     

    https://discussions.apple.com/thread/5156535?tstart=30

     

    What all USB things are connected, especially maybe the second monitor?

  • 6. Re: iMac display turning off randomly with external monitors
    mrbofus Level 1 Level 1 (5 points)

    That does seem to be somewhat related; mine isn't flashing over and over, and for me, it's the built-in iMac display that isn't functioning properly.  The external monitors have never spontaneously turned off.

     

    Thank you for pointing that thread out to me though!

     

    As for USB stuff, nothing is connected to the monitors themselves.  On my iMac, I have a secondary webcam plugged into one of the USB ports, a printer in the second, and the occasional iPhone and iPad in the third when I sync those devices.  The fourth remains open for when I need to plug in thumb drives or external drives.

    Hi, I have the same problem but on an IMac 2010.

    Did you managed to find a solution?

  • 8. Re: iMac display turning off randomly with external monitors
    mrbofus Level 1 Level 1 (5 points)

    Unfortunately, no.  I'm keeping my figners crossed that Apple's next software update will include a fix for this issue.  Not holding my breath though. 

  • 9. Re: iMac display turning off randomly with external monitors
    mrbofus Level 1 Level 1 (5 points)

    Just as an update:

     

    It seems like it's a sleep related issue, in my case, at least.  If I don't let my iMac go to sleep [ System Preferences -> Energy Saver -> Computer Sleep: Never ], then all three monitors stay on.  If I let the iMac go to sleep, there's a pretty good chance the iMac's screen won't come back on and then randomly turn on and off.

     

    Ideally, I would like my iMac to go to sleep so it's not using power when I'm not using it, but for now, I guess I'll have to keep it from sleeping.

     

    If anyone else experiencing this issue would like to try setting their computer to not go to sleep and seeing if that fixes it, please do so and report back to see if we can try to isolate the cause.

    Sometimes multidisplay arrangements will not stick in OS X after performing software or hardware modifications.

     

    This could be corruption in the settings file for display arrangements, which is a common reason why settings for any application or process cannot be saved or restored. Try to clear the window server settings and have them be rewritten by the program, which can be done by deleting a certain file

     

    Firstly disconnect your external display

     

    Then go to the Finder and choose the Library option from the Go menu (hold the Option key to reveal the Library in this menu if it is missing). Then navigate to the Preferences/ByHost folder in the window that appears, and remove the file called "com.apple.windowserver.NUMBER.plist

     

    After performing each of these steps, try logging out and logging back into your account and connecting the external display..

     

    NOTE: This will change your display settings to default as well so you may have to re-adjust afterwards

     

    Hope this helps!

    I don't think this is an issue of a multi-display setting not sticking; it's the iMac's screen, not any external monitor, that just randomly turns off.

    Check your console dump...

    Many answers with suggestions to follow. Anytime Apple issues an update, I perform it and:

    - delete all caches (Onyx)

    - perform permission repair

    - perform PRAM reset

    Many say those operations are useless but as many have strange problems here and there after the update, I don't.

    Cheers

    Oh, definitely!  I didn't mean to imply that it wasn't worth a try.  I was also incomplete with my response.  I did try that and that had no effect.  The end result is still the same.  If I let my computer go to sleep, most of the time, the iMac display is very glitchy.  If I don't let the computer go to sleep, the iMac monitor is mostly fine and is only occasionally glitchy.  So for now, the only solution I have found is to not let the iMac sleep at all.
