Windows 10: USBC DisplayPort on Thunderbolt Doc Not Working

I have two external monitors plugged into a thunderbolt docking station, one connected from displayport to usb-c displayport and one usb-c to usb-c. Today the usb-c displayport stopped showing anything on the monitor hope this makes sense!. I swapped the plugs so the hdmi was plugged into the usb-c and the usb-c was plugged into usb-c displayport and sure enough, the issue is with the usb-c display port not working.In my display settings, it still shows the three monitors laptop, and two external but the monitor itself says Input Signal Not Found. When I open windows they open up on that s

thunderbolt 3 to displayport adapter

Hi John,



Thank you for writing to Microsoft Community Forums.



I understand that inconvenience you are facing when the things may not work as expected.

1. What is the make and model of the computer?
   
   
   

When the Thunderbolt 3 is used with certain eighth generation Intel processor-based Windows 10 systems, there is a possibility that the two USB 3.0 ports on the back of the dock (closest to the Ethernet port)
may not be recognized properly by the operating system.





However, I would suggest you to follow the steps mentioned below and let us know if that helps.

1. Disconnect the pluggable Thunderbolt 3 dock from the system and remove its power cable to turn off completely.
   
2. Uninstall the Intel ‘Thunderbolt Software’ present on your system via the Control Panel ->
   Programs and Features and restart the device once.
   
3. Download and install the latest version of the Intel Thunderbolt Software published by your system manufacturer. If you are unable to obtain this download from your system manufacturer, you can download a version directly from Intel
   here -> https://downloadcenter.intel.com/do...-Driver-for-Intel-NUC-Kit-NUC8i7HNK-NUC8i7HVK
   
4. Restart the system once again.
   
5. Reconnect the power cable to the pluggable Thunderbolt 3 dock, and then reconnect the Thunderbolt 3 cable from the dock to your system.
   
6. You should be prompted to authenticate/approve the dock. Follow the onscreen prompts for the completion of the process and check the status of the issue.
   

If the issue still persists I suggest you to get in touch with the
Thunderbolt support for the further assistance.





Hope it helps.

thunderbolt 3 to displayport adapter

I have a problem with a thunderbolt 3 to displayport adapter. It's actually thunderbolt 3 to HDMI, though it conforms to the displayport spec. When I use my laptop without it connected like at home then put the laptop to sleep and I come into the office
and connect it windows detects that it's connected but there is no signal on the monitor. I have 3 monitors and it doesn't matter which one it's connected to. Windows shows the monitor is active and is at the correct resolution. If I unplug the HDMI cable
from the back of the monitor windows detects that the monitor was removed and it is no longer available. I have to reboot the computer to get it to work.

I'm not sure if it's the adapter because at this point it's the only thing I haven't swapped, well and the computer also. I don't have another laptop with a thunderbolt 3 to displayport capability to test with. I'm going to get another thunderbolt 3 to displayport
adapter and see what happens, but I wanted to start this discussion before I get it to see if there are any possible solutions outside that.

I did force the monitor to default to the HDMI port. I also tried another HDMI cable, though I'm not surprised that didn't fix it.

Thanks,

John

 

USBC not recognizing mini doc after sleep mode

Hello,

I am running my second monitor from a mini doc connected to the USBC port of my laptop (specs below). After my laptop is in sleep mode and I turn it back on, it does not recognize the mini doc so my monitor does not turn. The only way to use this second monitor is to unplug the mini doc and plug it back in.

Is there a way for my laptop to automatically recognize the mini doc connected to the USBC port after it was in sleep mode?
