    How can I connect to an Apple Thunderbolt Display

    pfps

      I have a laptop (a Lenovo Yoga 920) with Thunderbolt ports powered by an Intel Thunderbolt JHL6540 chip, which gets identified as a 15D2 controller.

       

      When I plug in an Apple Thunderbolt Display, I am asked whether to connect to the display, but then nothing happens and the display doesn't turn on.  There must be something missing, but what?  I'm running driver 17.1.64.6, which is current, under Windows 10 Home 1709.

       

      The same display (and Thunderbolt 3-to-2 converter) works with a Dell laptop that contains an older Intel Thunderbolt chip running an older driver, so it is possible to make this work under Windows 10.

          Hello pfps 

          Thank you for joining the community.

          To investigate better on the case could you provide us with the following information?

          Can you provide us with the Dxdiag report following these steps?

          1. Use the win logo key +R
          2. Type DxDiag then “OK”
          3. Use the “save all the information” option
          4. Save the file to your desktop
          5. Please attach the .txt file to the thread
          Could you let us not what specific model of the Lenovo Yoga 920 you have?

          What kind of video cable is used for the connection?

          What is the model of the display?

          Can you provide us with the Intel® System Support Utility for Windows* report? Please attach
          the result to the thread

              Hi:

               

              I'm traveling and can't access the display this week.  I'll be back next week and try it out again and get the information then.

                OK, here is the information.

                 

                The laptop is a Lenovo Yoga 920 model 131KB with 16GB Ram and 4K

                touchscreen.  It has two USB-C ports with Thunderbolt 3 under a Thunderbolt

                Controller 15D2.

                 

                I have one ThunderBolt 3 port connected to a StarTech.com Thunderbolt 3 to

                Thunderbolt converter TBT3TBTADAP which is connected to an Apple Thunderbolt

                Display (which has an internal Thunderbolt hub) using only the display's

                cable.  The same behaviour occurs using the Apple Thunderbolt 3 to

                Thunderbolt 2 converter.

                 

                Apple is bad at putting model numbers on their devices, but there has only

                been one version of the display as far as I know, model number A1407.

                 

                I have attached DxDiag and SSU output with the display connected.

                 

                When I boot with the display attached or plug the display in I get a pop-up

                titled Approve Thunderbolt Devices, with Apple Inc., Thunderbolt Display

                listed.  If I select Always Connect and OK the pop-up goes away but the

                device is not connected.  It does show up in Attached Thunderbolt Devices in

                the Thunderbolt Software application, but not in Manage Approved Thunderbolt

                Devices.

                  Thank you for the information provided
                   
                  We can start by verifying that the thunderbolt drivers are up to date, you have motioned that you are running 17.1.64.6 on the manufacturer site you can find the version 17.1.64.250 here is the link update the drivers

                  Does the system work if you connect it to another Thunderbolt display?

                    I went to that site and downloaded 

                    Intel Thunderbolt Driver for Windows 10 (64-bit) - Yoga 920-13IKB, Yoga 920-13IKB Glass 17.1.64.250 22 Jan 2018

                     

                    I ran the downloaded file and got a window saying

                     

                    Setup - Intel Thunderbolt Driver

                     

                    ...

                     

                    This will install Intel Thunderbolt Driver version 17.1.64.250 on your computer

                     

                    This then gave a Destination Location of 

                     

                    C:\DRIVERS\ThunderBot

                     

                    which seems strange, but I accepted it.

                     

                    I then ran the program what was suggested and got to the device-driver installation wizard.  It ran and appeared to work fine, but the completion window said that it was installing drivers named

                     

                    Intel(R) Corporation (nhi) System (06/06/2017 17.1.64.6)

                    Intel(R) Corporation (TbtMpDrv) Net (05/14/2017 17.1.64.2)

                     

                    I rebooted, but the device behaviour did not change and the driver for the Thunderbolt(TM) Controller - 15D2 still has version 17.1.64.6

                     

                    Either this is the most recent driver or the installer on the Lenovo site is somehow broken.

                     

                    I only have access to the one kind of display, but both of them act the same.

                     

                    My colleague has a Dell laptop with a Thunderbolt port, and the display works fine on that laptop.   The Dell laptop has an older Thunderbolt chip and older drivers.
