Thunderbolt display bootcamp issue

Hello,
I'm having trouble with my MBPr 2012 and my thunderbolt display in bootcamp.
The display is recognized (usb, ethernet, sound and camera are working fine) but I have absolutely no video on the display.
It does not appear in the control panel, only the built-in display shows up.
Tried to download the nVidia driver again, not working
Bootcamp driver not working.
This was working fine yesterday, and today it just stopped.
No problem on Yosemite, everything is working.
I'm running Windows 7 ultimate.
Every update are done for the thunderbolt display
Thanks in advance.

Same thing for me too.  Late 2012 13" MBP Retina.  I have to unplug the Thunderbolt cable and plug it back in.
This has only started for me in the last two days.  The first two weeks of Mavericks was ok.
Update:  I just got back from a trip.  I was using the laptop separate from the Thunderbolt display.  I hadn't restarted since I returned and connected the monitor.  I've just rebooted, and put the computer to sleep.  After resuming from sleep, the display is ok.  Maybe try rebooting?  I'll update if it continues.

  • Macbook, Thunderbolt display, Bootcamp problem.

    I have a Macbook Pro connected with Thunderbolt display. The Macbook has Bootcamp 5.5 and Windows 7 Prof 64-bit. When working in Windows the screen gets blank, but network and USB are still working. Sometime the screen of the Macbook goes blasnk also, not always. After that Macbook does not turn on when disconnecting the Thunderbolt display. This issue is also in OS X Mountain Lion.
    2 weeks worked without any problems, but this started yesterday and today the issue was too time consuming.

    If you read the tips in Boot Camp Assistant, you would know that only Windows 7 is supported with Lion.
    The DVD if it was sold as physical media and your computer is listed as supported, but if you burned an ISO image and did not reduce burn speed to slowest, it will not be accepted or work (even if it appears to install).
    BCA sets the default boot OS volume to the Windows FAT "BOOTCAMP" so that Wndows can restart multiple times to install and update on its own. YOU have to format to NTFS during install.
    And you need to go to OS X control panel (system preferences) and use Startup Disk to make OS X the default again.

  • Thunderbolt Display has issue with weird washed-out colors after waking from sleep (after upgrade to Mavericks)

    I've got a Thunderbolt Display that I use with my Macbook Air (mid 2012) - usually in clamshell mode.
    When I let the computer go to sleep, and then wake it up by clicking the mouse, the monitor turns back on but the colors are washed out and purple looking. 
    The display goes back to normal when I unplug and replug it to my laptop.
    I first noticed this problem after upgrading to Mavericks.
    I made a video demonstrating the issue here:

  • Thunderbolt Display Configuration Issue

    Hello!  I am using a new 13 inch MacBook Pro (running Mavericks) connected to two 27" Thunderbolt displays (one tilted 90 degrees, the other in its regular position).  Sometimes when I connect my computer to the displays the picture on the screen appears in an incorrect configuration.  For example, the monitor that is supposed to be configured to show sideways (90 degrees) shows as a regularly configured monitor.  I did not have any of these problems until I upgraded to Mavericks.  Thanks in advance for your help.

  • MBP Bootcamp install of USB Windows 7 , Thunderbolt Display

    We need support from APPLE! BootCamp
    Here are my issues.
    Like many users, I must abandon the marvelous os x, and head to the darkside -  Windows 7 for work.
    I have a MBP early 2011. I must use Bootcamp, because of the resource hogging the 3d CAD programs I use. have tried to in the past with VMWARE, Parallels ect. with no luck
    I have a Corsair Force GT ATA 120 gb SSD III,  installed and my optical drive removed to accommodate my original Hitachi.
    Remember, not to Install that Hitachi drive, until you have used a CD only install of windows 7 onto the SSD.
    Why?- You can not boot from a USB disc that I am aware of, or use an external optical drive case, for your superdrive.
    This is not ok, we need the capability to install windows 7 from something other than a CD. I went to reformat my SSD I was forced to open up my MBP case again. to reinstall the Super drive. Install Windows 7, then remove my superdrive and reinstall my 500gb Hitachi.
    This is a royal, pain in the butt.
    If a mac air has the capabilities of installing windows 7 from a usb APPLE, please give same rights to MBP.
    Additionally, my osX runs like absolute garbage on the SSD, I rarely if ever use it because of the constant pinwheel I receive, I have researched this error, with
    little or no luck, using apps like TRIM seem not to help.
    I also own a thunderbolt display, and the fact that there is no support on connecting it without restarting the computer is also an issue.

    Because you will need the internal superdrive to install Windows.

  • Connecting 2 Thunderbolt displays to imac using bootcamp

    Hello all and festive greetings!b
    I bought an imac5 retina display yesterday and connected it normally and works perfect with my 2 thunderbolt displays either side.
    I now tried to set up bootcamp (for work I can only use bootcamp due to my nature of work) and I can only seem to get one of the thunderbolts to work. The other is working fine, the sound actually comes out of it! But when I press Screen Resolution I can only see the imac and thunderbolt "1" display instead of having an option to add the third monitor.
    Usually you have a desktop/laptop and add two monitors but because the imac is a computer that is a monitor too it makes it difficult to get around.
    Thanks in advance for all your help
    FWIW, I'm using windows 7 pro.

    I am specifically interested if the TB monitors are connected to separate TB ports of the iMac or are daisy-chained? These two configurations work very differently.

  • Thunderbolt Display in Bootcamp: Wont 'wake' after comp goes to sleep, and wont respond to dim controls.

    Hi, I am using a 2011 iMac and my thunderbolt display arrived today.
    I use bootcamp (win7) and the display works fine on start up, 2 issues though:
    1. Keyboard brightness controls affect the main display but do not not change the thunderbolt display.
    2. After the computer goes to sleep, apon waking the thunderbolt display stays off.
    Any advice would be appreciated.
    Cheers!
    Sam

    I have no idea about changing from Helpful to Correct. (but feel free to mark this one as correct).
    Fixed in the next update  in what way?  So that the brightness buttons control both at the same time?  Don't hold your breath waiting for it.  This has been an issue with all the displays for a long time and I doubt this will happen.  The problem is that the screens can get out of sync (like if you enable the option to automatically adjust based on the room brightness) so that the brightness wouldn't be the same between them.  Who know, perhaps they will come up with this fix and allow them to sync properly.
    I don't know of a Windows program but on OSX, I use ControllerMate to do this for me.  CM allows you to customize all your buttons to do different (or additional) things.  In my situation, I have the external keyboard attached to a 27" Cinema Display.  When I press the brightness keys on the external, OSX detects the keys and adjusts only the CD brightness.  However, CM is also monitoring the keys and when I use them, it emulates the same brightness keys being pressed on the laptop keyboard.  This allows me to control the brightness on both at the same time.  If needed, I can press the brightness keys on the laptop and adjust that screen seperately because I haven't programmed CM to monitor those keys.

  • 1x cinema and 1x thunderbolt display on bootcamp

    Hi there,
    as I couldn't find any useful information yet, I'll try my luck here.
    Here's my setup:
    1x Cinema HD display (23") connected with an DVI to Mini-Hdmi cable to a Belkin Thunderbolt Express Dock, which is connected with my thunderbolt display. The TB display is connected to my Macbook pro 8.1 (graphic card: Intel HD 3000).
    Now when I boot with MacOS, there's no particular issue, both external display light up, meanwhile the internal Macbook displays stays black, I suppose that's normal.
    On the other hand, if I boot with Windows on bootcamp, the cinema display (beeing at the end of the daisy chain), is recognized in the device manager but I can't manage to get an image. In the Intel control panel it's not detected at all. USB sticks or external drives connected to the screen are recongnized without any problem, the only thing that's not passing through is the image signal. I tried this with several drivers and with Windwos 7 and Windows 8, but coulnd't find a possibility yet.
    Is there anyone having the same issue?
    cheers,
    ginster

    is no one having the same issue? Can anyone confirm that it is working for him? Personally I think it's a driver issue, but apart from the latest avaible Intel drivers I don't find any other alternative drivers.

  • I have a new (mid-2011 27" Imac with 2 Thunderbolt ports each driving one 27" Thunderbolt display. The 3 displays work perfectly in OSX Lion but in Bootcamp 4.0 with Windows 7 (64 bit) only 2 screens come up. everything is up to date. Anyonce who can help

    I have a new (mid-2011 27" Imac with 2 Thunderbolt Ports each driving one 27" Thunderbolt display.
    Graphic card is AMD Radeon HD 6970M  with 2Gb of VRAM.   All works 100% in Lion but
    in Bootcamp 4.0 running windows 7 Professional (64 bit) Only 2 of the 3 screens work not all three.
    Tried updates, calling Apple etc. But no luck.  Windows doesn't recognize the 3rd screen while
    checking on the driver in windows is tells me it's the latest and best available. ?  In VMware
    Windows 7 also works fine over three screens so windows can do it. But I need it natively to
    work. (i.o.w. in Bootcamp). Does Anybody know how to solve this, or if Apple is working on a
    solution for this ?  It really hurts to have one of these expensive screens staring at you being dead.

  • I need help getting my Thunderbolt display to work with Windows 7 through Bootcamp.

    I recently bought a thunderbolt display and it works great in my Mac environment.  But I recently added Bootcamp and Windows 7 (I need since my Broker Dealer only uses Internet Explorer).  Unfortunately, I can't seem to get Windows to recognize my Thunderbolt display.  Today, I spent 2 hours with a very kind advisor from Apple Support but we didn't have any success.
    Here's my setup:
    MacBook Pro (purchased new in 2011) with i7 processor
    Thunderbolt Display
    Lion OS (all updates installed)
    Bootcamp with Windows 7 Ultimate 64-bit (all updates installed)
    With the help of Apple Support, I downloaded and reinstalled (through the repair option) all the Bootcamp drivers.  I shut down my computer, plugged in the Thunderbolt display, turned it on and booted into Windows 7.  When the Windows Welcome screen appears, it shows on my Thunderbolt display for about 2-3 seconds.  But the thunderbolt quickly goes black.  My MacBook Pro changes to a 640x480 resolution and the Thunderbolt remains blacked out--with no signs of even a single flicker.  Once the computer finishes the start-up, my MacBook Pro remains in a 640x480 resolution, with no option to change the resolution (it's grayed out in Windows control panel).  If I unplug the Thunderbolt cable from my MacBook pro, the high resolution of my MacBook pro snaps back to normal.
    To me, this seems like some type of driver problem but I must be missing something simple because it appears that Thunderbolt works with Bootcamp and Windows 7--based on some of the readings I've found here in the Apple support community.  I'm most appreciative of anyone's help here.

    No idea if Windows will do it, but you can run Windows without Bootcamp & have OSX available at the same time, which should give you all the Monitors that OSX uses.

  • Thunderbolt display issues

    I went to the Apple store yesterday with my Macbook Pro to test a Thunderbolt Display.
    The store assistant attempted to demonstrate it to me (I say attempted!), but he couldn't get it working. Basically, when he connected my MBP to the display with the Thunderbolt cable, it worked to an extent, but it wouldn't....
    - fill the full resolution of the Thunderbolt display (2560 by 1440 pixels) in Mirror mode - my graphics card is meant to support external displays up to 2560 by 1600 according to this - http://www.apple.com/macbookpro/specs.html
    - it also wouldn't work when we closed the lid. The TBD just went blank.
    We tried it on two different Thunderbolt Displays. My MBP has all the updates required as far as I'm aware.
    Can anyone suggest what we might have been doing wrong? Does my Macbook Pro need to be connected to a power outlet to work with the Thunderbolt display correctly?
    By the end of the hour in the shop the shop assistant suggested that it may be a problem with my graphics card? I can't decide whether he's right or he just didn't know what he was doing!
    Also, since then, when I open iMovie on my MBP, the bar at the top of the screen (the one that says what program you have open) says that iMovie is open, but it does not display the actual workspace itself. When I click on Mission Control the iMovie workspace appears, but then minimises again when I click out of mission control.
    Any help would be great. That's the last time I let an Apple store assistant muck around with my computer!
