Q: Windows 10 thunderbolt display not working

I had upgraded my late 2013 MacBook Pro to Windows 10.  The Bluetooth driver didn't work, but just about everything else did.  I just updated Boot Camp and now my Thunderbolt display is not recognized by Windows.  I've reinstalled the Boot Camp 6 update, rebooted, etc.  No joy.    Anyone encountered / solved this issue?

MacBook Pro with Retina display, Other OS

    1. Does the TB display work properly on the OS X side?

    2. If you have a TB-to-Ethernet adapter, can you test if the Ethernet connection works properly. The same thing can also be tested with TB-to-FW adapter, or another TB-to(HDMI/DVI/VGA).

    3. Do non-TB monitors work properly in Windows?

    1. Yes, Works fine in OS X.
    2. USB and Ethernet on the TB Display work in Boot Camp.
    3. I'll try a TB to HDMI/DVI/VGA adapter tomorrow.  I've never had any luck with them in the past using boot camp.

     

    Thank you.

    Clarification question.

     

    a. Windows is running, you plug the TB cable in. Are you saying USB ports and Ethernet ports are live and usable and Display does not work?

    b. Windows is down, plug the TB monitor cable, boot and/or switch to Windows, and USB and Ethernet work, but the Display does not?

    b.  If i boot to windows with TB inserted, USB and Ethernet work but display does not.

    This is expected since Bootcamp drivers do understand the TB hot-plug.

    b.  If i boot to windows with TB inserted, USB and Ethernet work but display does not.

    This indicates a problem with the Graphics driver, not the TB driver. What GPU do you have? 13-in is Intel-only, but 15-in is Intel/nVidia GT750m. What are the GPU driver versions?

    Under About This Mac | Displays, it lists, "Intel Iris Pro 1536 MB"

     

    I found the driver install from Intel and it is working.  Thank you!

    Doc,

    New MacBook Pro 15 Retina with GeForce GT750M.

     

    I can't get the TB to work my secondary display.  (HP LA2405x)

     

    The NVIDIA app shows the Windows 10 Driver 355.82 released 8/31/15

     

    Any suggestions?

    Do the ports on the TB work, but just not the monitor? Older Macs do not support TB hot-plug. GT750m is a 2013/2014 model.

    MacBook Pro 15 Retina is a 2015 model.  I could not get WIN7 boot camp to work at all and found out the 2015's dropped WIN7.  So I went with WIN10 and it works fine, except for the TB display.  Don't have any other need for TB, so not sure how to verify.  Plus first Mac ever, so not Mac peripherals to test.

     

    It looks like others have trouble with TB display in WIN10.  But as on this thread, were able to get it to work.

     

    I Updated the Boot Camp drivers with BCA two times, with no luck.

    Run the same test as DrDroop and check if Ethernet or USB or FW on the TB display work or not. Since you have a 15in, we may need to check the drivers. Do you have any unknown devices in Windows Device Manager? Was your W10 an upgrade or a clean install?

    1. Are Thunderbolt devices “hot pluggable” using Windows with Boot Camp?

     

    Thunderbolt hot plug is supported under Windows 8 or 8.1 on all 2014 and later Mac computers.

    For all other Mac computers, Windows 7, 8, and 8.1 scans and activates Thunderbolt devices connected to Thunderbolt ports only during the Windows startup process. If your device was not plugged in at start up, Windows will not detect it without a restart.

    I have iMac 27 inch w/Retina. I installed Windows 10 via Boot Camp.

    I added an external monitor (Toshiba TV Monitor which works fine as a secondary monitor with Mac OS X on this iMac 27 w/Retina).

    The external monitor is simply NOT recognized in Windows 10. I rebooted with it plugged in, etc. I attempted to install a new WIndows driver for the AMD graphics card, etc.

    The weird thing is, I had a 21.5 inch iMac for a week (I took it back and upgraded to the 27 inch). During that week, I had windows 10 installed on it and the same external monitor worked fine, in both Mac OS X Yosemite and Windows 10. For real.

    My conclusion is, one of two things is going on:

    1) The 27 inch iMac w/Retina's AMD graphics card is the issue (as it is the only difference in the scenarios), or

    2) One must have the external monitor hooked up and on while preparing and installing the Windows 10 installation. In other words, maybe Thunderbolt itself is not recognized because nothing was hooked to it while running Boot Camp Assistant. But I be damned if I'm going to reinstall Windows 10 again.

    Any way to tell under Windows 10 if Thunderbolt is working? I have no other Thunderbolt peripherals to try.

    You can try and SMC Reset and a NVRAM Reset and test. How is the Toshiba connected to the iMac? TB-to-HDMI?

    It is connected via the TB-to-HDMI. Again, the monitor works as expected under Mac OS X on this computer, just not in Windows 10... And it worked under windows 10 and a different iMac 21.5 inch. Mine is a 27 inch retina.

    As for the SMC reset... isn't that achieve simply by powering down, unplugging from the wall for a 15 seconds, then plugging in for 15 seconds, then powering up? Done that. And the same to the monitor. And the monitor is on during a boot up directly to Windows 10.

    As for the NVRAM reset... can that harm my computer other than me losing time-zone, monitor resolution, etc? It's a new iMac. lol. It's my baby.
