- When did you buy the unit?

- Did this configuration (NUC+ one monitor on HDMI+one monitor on thunderbolt) work fine before? If yes, was there any recent change related to the point when the issue started?

- Could you please provide a video or some pictures showing this behavior?

- Did the error happened while using our Intel® Driver & Support Assistant to update the driver or did the pop-up error message appeared after you manually tried to install the driver?

- Have you tested your NUC with a different monitor and a different thunderbolt cable?

- Did you physically inspect the thunderbolt port to see if maybe has some dirt in it or if it’s maybe loose?


I look forward to hearing from you.

Hello Victor!

I'll take it from here, as I'm experiencing the same problem. The USB-C connection not working is what motivated the manual installation of this driver. Note that it also happens when connecting to only one monitor via USB-C - USB-C, HDMI is working correctly. I have attached the report from the Intel SSU app.

- My unit was bought in May 2020 (Intel NUC Kit NUC8I5BEK2 | Core i5 8259U)

- Yes, it has worked in the past. I had the opportunity to try it during one day, several months ago, and it worked just fine. In the meantime I have just been updating the software when suggested by both Microsoft and Intel.

- A video of the behavior was attached. It usually blacks out for longer periods when connected just via USB-C, the HDMI connection somehow "strengthens" the connection. Note that when accessing the BIOS the issue does not occur.

- 2nd option.

- No, because it worked in the past I just tried with another cable, producing the same result. Also, to rule out the possibility of the monitor being broken, I connected it to a MacBook Pro via USB-C and it worked as expected.

- Yes, there is no visible debris nor apparent damage.


I hope that this is helpful.

Hi Bruno,

Please open a thread of yours and I'll give you advise what to do. Your problem may looks similar, but in my opinion is not caused by thunderbolt firmware.
