How can I connect to an Apple Thunderbolt Display

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.

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.

Hello pfps

 

 

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

 

 

https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/yoga-series/yoga-920-13ikb/download... https://pcsupport.lenovo.com/cr/en/products/laptops-and-netbooks/yoga-series/yoga-920-13ikb/download...

 

 

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.

Hello pfps

 

 

Thank you for your response

 

 

Seems that we are facing a comparability problem with the setting the Lenovo and the apple thunderbolt display we can try to contact Lenovo support for them to try to replicate the situation with the same scenario

 

 

https://pcsupport.lenovo.com/cr/en/contactus https://pcsupport.lenovo.com/cr/en/contactus

 

 

They can also provide guidance for the driver update that in this case did not make any change on the system

Hello...

I am experiencing the same issue. I have an Apple 27" TB Display, and it connects just fine with my HP Spectre laptop...

However, I recently upgraded to a new Gigabyte Aero 15, and when I plug the display in, the connection window pops up. I click "Always Connect" but nothing happens...

When I look at the TB attached devices, it says recognizes the display, but is not connected, and I can't get it to connect...

I'm currently running the latest 17.4.75.250 software package drivers. My HP had 16-dot something drivers. I can find them, but Intel's install program will not let you downgrade, so I have no way to go back to those drivers to see if they would work.

Can you suggest a solution?

Best,

Ben

Unfortunately I don't have any idea of what to do to fix the problem.

I did notice something in one of the Intel driver updates about no longer supporting host Thundebolt 2 hubs. Maybe that did something to also no longer handle Apple TB displays.

I expect that the only way to get action would be to get the Intel driver decertified because it doesn't work correctly. That would force action from Intel I expect. However, I doubt that we little people can get the decertification to happen.

Thanks..

Howdy...

I have installed the new driver per your request but nothing has changed..

When I plug in the monitor, it still discovers it and asks me to connect, after I choose 'always', nothing happens... Just a blank screen.

Can you please help?
