Screens Blacks out during Remote Desktop

I have a 2008 iMac running Yosemite (up to date) with a boot camp partition with Windows 7 (fully updated). Running in Windows 7, I start Internet Explorer 11 and go to my company's remoting website and initiate a remote desktop connection. While there everything works great but at random intervals from a few minutes to about 40 minutes the screen suddenly goes black and I cannot get it to be visible again. I end up having to power down the computer by pressing the power button for about 12 seconds and restarting.
In ONE case, I left it running in Windows 7 overnight and it was black by the next morning, though in that case I was trying to power the computer down, but instead of powering down, the screen brightened up.
This is VERY irritating. I have tried turning off Windows 7's screen saver which had no effect. I have also tried minimizing the remote desktop connection and moving around some windows thinking the original non remote window might be timing out somehow, but again no effect.
Anyone have an idea of what I could try. Note that in OSX, I NEVER see a problem. When running in Windows XP in Parallels, I also never see that problem. On my other computer (MacBook Air) I have a parallels Windows 7 virtual machine and I don't see the problem there either.
Thanks.

  • Mac Mini 2011 screen blacks out during heavy screen activity

    I have a Mac Mini 2011 i5 2.3Ghz with Intel HD video.  It's connected to a 30" LCD 2560x1600 (Dell WFP3008) via mini-DP to DP cable and a 22" LCD 1920x1080 (Samsung LCD TV) via HDMI to HDMI cable.
    For the first few weeks I had it connected to the 30" only and it was fine.  Then I hooked up the Samsung as a second display and the problems started.
    The problem is that the Dell blacks out briefly, then comes back.  It is not "drawing" the screen black, the signal to the Dell gets disrupted momentarily so the monitor has no signal so it goes black.  Then it resyncs with the signal and the display is back.  This only happens to the Dell, during the disruption, the Samsung image stays put.  I know it is a signal disruption because the Dell shows a displayport icon showing that it has just resynced to that input.
    The problem happens more frequently when more things are going on; like if I have a window or multiple windows playing video, then the disruption happens more.  If I disconnect the Samsung, it happens less.  It could even happen if a web browser window taking up a large portion of the 30" screen does a full page update, it will disrupt.  If I am running Adobe Lightroom, it seems to happen more also.
    When it happens it seems like messages like this appear in the console, although i can't say they are directly correlated:
    6/1/12 8:28:46.000 PM kernel: IOSurface: buffer allocation size is zero
    I'm thinking perhaps the mini is running low on memory since the 2560x1600 is pretty high res and then add the 1080p screen and stuff being updated, perhaps it runs out of memory and disrupts the signal while it garbage collects?  Pure speculation.
    Has anybody else seen this and have any clues on how to resolve it?  Thanks.

    I should clarify that when I say perhaps the mini is running low on memory, I mean low on shared video memory, since the computer has 16GB installed.  I'm not sure how to view or test shared video memory allocation.

  • My imac's screen blacks out during booting

    MY imac froze and restarted recently, then when i got into the computer it froze and shutoff again.  This time when i tried to turn it does one of a few things... 1 it only gets to the Apple logo then blacks out, 2 it goes to the place i requested by key commands, or 3 it has the Apple logo, then a loading bar that only loads for about a second and only reaches a very very small fraction of full capacity, then lastly goes to a spinning loading wheel that lasts 5 seconds at most then it blacks out once again. 

    We do not know which iMac or what OS X your on, but that sounds like a hardware problem.
    Run the Apple Hardware Test, as per > Using Apple Hardware Test and report the results either here or to your local Authorized Service Provider.

  • Screen blacks out during install of 10.6

    Just installed Snow on a Mac Mini and a first gen Intel MacBook Pro. In both cases I lost the video part way through. On the Mac Mini I had to do a restart and the install picked up where it left off. The MacBook Pro had a screen image but no monitor back light, so I had to use a flashlight to go through the install process again in order to see the cursor and screen instructions because I interrupted the install with a power button restart. If you experience a black screen but can just barely make out something on the screen, DO NOT panic and decide to restart. Get a bright light on the screen and you should be able to see the progress bar after you wake up the screen dimming. Before you install set your screen dimming to never. Hope this helps.

    It happened this morning again. Attached a picture I took of my MacBook when it went dark. I have to close the lid to sleep and wake up again to regain brightness.

  • My screen blacks out during phone use.

    Wondering if anyone else has had this issue ...yet.
    Started on Friday 1/20 while watching a you tube video, thought it was going through a random reboot.
    Screen  barely powered on while trying to fix then randomly starts back up.
    Happened again Saturday while on Facebook. Did a battery pull.
    Then again Sunday using Facebook, once again.
    Just curious though... anyone else?
    Also, if I have to take it back to the store for the issue that should be covered by factory warranty are they good with in store switch of a new phone?
    I used to get those when I had my En-V2
    Don't know if smartphones have different ways...
    Thanks

    Limelemoneez, thank you for sharing your concerns with your device. I have not seen this issue with the Nexus so far. Since this seems to happen mostly when using the Browser and web applications, have you tried clearing cache from your Browser? If not, try this first. Open your Browser, press the 3 dots to go to Settings, choose Privacy & Security, clear cache. If you have installed any antivirus applications, please uninstall those. Also, if you notice this started after installing a new application, please uninstall that app also.
    If this issue is still occurring, then I suggest completing a factory reset. This will erase all data from the device and reset to factory default settings. Since this phone does not have an SD card, I would recommend connecting to your computer to backup personal info like pictures, videos, etc. Also, check your Gmail account to make sure pictures backed up.

  • Screen Blanking Out During Phone Calls - Solution

    Previously I noticed many posters complaining about a problem with their iPhone screen blacking out during phone calls. I think I may have found the solution, or at least a solution. I have been advised by the Apple Store technicians that the case I use (and indeed, many cases that are sold in the Apple Store), are so opaque that they block the sensor found near the earpiece. This is the sensor that tells the iPhone screen to black out when it is next to your ear, and to light up when it is away from your ear. Because it cannot sense through the case, it still thinks it is next to your ear and hence keeps the screen blacked out. And sure enough, when I took my iPhone out of the case, the problem disappeared.
    Now here is the question - has anyone got experience with a good case that does not cause the above problem? And those who do have a problem case - have you been able to return or exchange it with the manufacturer?

    You have this product - which is specifically designed for the iPhone 3G?
    http://www.iskin.com/revo2_features.html
    This is the case I've used with my iPhone 3G for the last 6 months or so with no problem.
    There is an iSkin Revo for the first generation iPhone, which is not designed for the iPhone 3G since the proximity sensor and light sensor with the iPhone 3G are in a different location than the location for these sensors with the first generation iPhone.

  • Random laptop screen Black out / Turn off .

     Hi, 
     first of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
    to the problem now
    A few days ago my laptops screen started  out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen  had no lights, and if i use a flashlight on it there is nothing. like its turned off completelly.
    Before this happens. Ths behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a radom color (green mostly) then becomes black/shuts down.
     NOTE: The laptop keeps runing, i can hear the videos playing so it probably isnt a gpu chip or gpu issue , music and games.
    I searched the web for all kind of reasons that this could happen and tried some of the fixes .
    Here are everything i tried and all or the details i could accumulate in past coupe of days:
    1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered (  on both amd and intel ).
    2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
    3. I tried installing 4 different drivers all with clear install. ( didn't work)
    4. I tried to  to recover system with restore point. ( didn't work)
    5. I tried to lower the screen brightness. ( didn't work)
    6. tried this trick: 
    Turn off laptop
    Remove battery
    Hold the power buttong for 30-45 seconds
    Plug-in the charger ( dont put the battery in )
    Turn on laptop and see if it works.
    Very Noticable details:
    7.  Since  on of the rare fixes requires to move the lid  i tried shaking the screen a bit or pushing it slightly to different directions. This actually  does the trick and turns the screen back on ( i am right now typing  this after using this "trick"
    So, with this one as a hint there are a couple of stuff i have in mind but i am not sure  and need help since i am not a technician.
    a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
    b) I read that if you use a flashlight and you cant see  your desktop it means its a bad inverter.
    c) Can the inverter have a lose cabe instead of the lcd ?
    That's all the feedback i could give you that i can recall now.
    Currecntly the screen looks ok ( maybe its the certain angle it has after i moved it  so i would aprecciate a fast reply before  it goes black again
    EDIT: Tried to play a game for a few mins and i got the black screen again. Closed the lid  so the laptop goes in sleep mode then opened it and it worked. Just for the records.
    EDIT#2: Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers? 
    EDIT#3: Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed)
    thanks in advance
    Sincerely,
    Ntas
    P.S. Please feel free to ask me any question if you need more information, i am not a laptop expert but i know   more than the average person
    This question was solved.

    Hi @Ntas 
    I have read through your post and it seems there are a couple of possibilities, and I noted that you have already tried several of the things I would normally suggest.
    I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue.  Of course that last part may just mean the display is on its last legs, but hopefully not.
    First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.This manual is also useful in that it lists all the compatible parts, so if the display is defective you could use this guide to help order a compatible replacement if you choose to do so.

  • Screen blacking out?

    I am curious to know if anyone else has had an issue with their screen blacking out while using the number keys during a call? This has happened four times to me, and I called Verizon, but thought maybe I had put my finger on the on/off switch by accident. However, this happened Saturday again, and I was SURE I did not touch that area of the phone. Please let me know if this has happened to you so we can document this issue with Verizon/HTC.

    I am having the same issue. It blacks out or the screen flashes like it is "waking up" but doesnt fully wake up. It has happened on and off over the past two weeks. I thought it was due to a message coming through or a call but that's not the case. I will have to bring it in to see if it should be replaced. I am also experiencing ALOT of dropped calls. I have reset the phone but the issue happens as soon as I try to make the call again..... It driving me nuts.

  • Does anyone know how to solve my Ipad from blacking out during apps?

    My IPad is blacking out during apps and going back to the main screen.  It will do it in Outlook, Internet as well as games.  Does anyone know how to solve this problem?

    Sometimes its bescause you have to much memory being used up. Id try:
    1. Double tap the home button to bring up the bottom. Hold your finger down on any app until they wiggle. X out of any apps you are not using.
    2. Reboot. Hold the home and power button at the same time. Ignore the red slider. Until the screen goes black and the apple logo appears.
    Try your game or app again. I know if you have a bunch of stuff running in the background, and run a game like infinity blade or a high processing game. The app will close on you.

  • Screen Black Out since upgraded to 10.6.5

    During the update to 10.6.5 using downloaded DMG (from Apple site), my Macbook black out during the installation. My LCD screen became Black, couldn't brighten up using F2 (brightness control). I have to Share Screen from my other iMac to click RESTART after the installation.
    My 2nd black out happened just 20 minutes ago while I was in Mail program. My LCD turned black and couldn't brighten up. So I force Shut Down to restart my computer.
    Any advice on this because the 1st Black Out happen during installation, and today's the 2nd. It never happen before, could it be there's a bug in the software update to 10.6.5?

    It happened this morning again. Attached a picture I took of my MacBook when it went dark. I have to close the lid to sleep and wake up again to regain brightness.

  • 14" iBook screen blacks out

    This is the third time it's done it today and the 5th time ever. My AppleCare ran out the middle of March, so I guess they are right on in determining when it's time to get a new computer.
    When it blacks out, it just goes immediately, no flickering, no warning whatsoever. I can still see the desktop underneath the black and I can still move the cursor. I don't know anything what the insides are like, but the apple light on the top of the case goes out when the screen blacks out.
    When I closed the top and opened it again, it brought the screen back up right away. But this last time, it took a few closing and openings to get it to come back up, making me think it's going to get worse.
    Last week was the first time it ever went black. I initially thought it was falling in to sleep mode and held down the power key to get it to reboot. I'm pretty sure sleep has nothing to do with it, but I set my display to not go to sleep at all today to find out. It's blacked out twice since.
    I don't use a screen saver, it's happened on battery and power adapter. Other people have mentioned the fan not running, I can't remember ever hearing my fan run or else it's just so quiet I can't tell the difference between it and the hard drive.
    My iBook is a late 2004 model 14" 1.33 and, I just upgraded to Tiger (coincidence?) There have been no other problems to speak of other than the keyboard losing letters, battery needing to be replaced and the usual airport glitches. It hasn't been dropped or spilled on. Any suggestions on how to fix this and what I might be looking at when/if taking apart the screen?

    It sounds like you might have a bad inverter cable, especially since it is affected by the position of the display. I think this is just a mechanical failure of the cable caused by many openings and closings of the display.
    You might check out the troubleshooting section of the ifixit site and read about the inverter cable and see if it sounds like what is happening to you. I gather it is a real job to replace it. Ifixit and Powerbookmedic would be two good resources:
    http://www.ifixit.com/
    http://www.powerbookmedic.com/
    Since the job is considered very difficult, I'm not sure there are any instructions on how to do this on these sites. But there is another manual that might be helpful:
    http://node123.cit.geneseo.edu/~stratton/ServiceManuals/
    This is just the index. You will have to find the one for your iBook. Powerbookmedic also has a good manual.
    It may also be possible to repair the cable, but I don't know. Spudnuty is the real expert here, and hopefully he will see this and be able to offer you more specific advice.
    Good luck!

  • Screen blacks out after a few seconds and won't return to normal state.

    I have the 30 gig ipod photo that i got about a year and a half ago. Whenever I look at the screen to access music or anything, the screen blacks out like there's a screensaver or something and won't return back to normal. Even after I reset it, it stays normal for a few seconds and then blacks out again. The backlighting still works so it's just a bright black screen and I have function of the click wheel because it clicks everytime I move up or down. I already tried restoring it so I am all out of options. Anyone PLEASE HELP!!! Thanks
    Steve

    This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.

  • Screen blacks out for a few seconds occassionally

    Sometimes my screen blacks out for a few seconds, then comes back on again. I have an original Titanium powerbook. Is this a warning signal of worse to come? I know I should replace the computer soon, but it's working just fine for now. I just don't want it to die before I've moved on to a new machine.

    Hi Julie,
    Obviously no one can predict with certainty what the future will bring, but if I were in your shoes, I would certainly think there was worse to come.
    Many things could be causing this, but it sounds like a short circuit or bad connection, possibly with the display cables running through the hinges, or where they connect to the logic board. It could also be a sign of the display dying, though they usually just get dimmer and dimmer or simply die.
    Does the "blinking" correspond to any movement of the PB?

    my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone?

    I have to believe this has something to do with iOS 7 issues. I have taken my screen blacked out 5s twice to the Genius Bar and the found a bunch of system apps had crashed.  So if this is the case, is iOS7 the problem?
