HP OMEN 15 - ek0770ng - USB C Thunderbolt port not charging nor sending picture

[Elinea]

Hi all,

I received my new Omen 15 laptop a few days ago and am very pleased with the design and specs. I run the laptop on the USB-C (Thunderbolt) port on an HP E27D G4 display, which worked great at first. Unfortunately, I have not been able to get a picture on the display for a few days and the mouse and keyboard connected to the display are no longer available on my Omen 15. I have now completely reinstalled the Omen 15 laptop and had all the functions again for a short time, but they disappeared again after a few Windows & HP updates. I found info on the internet about a donwgrade of the NVIDIA driver, but that didn't help either. A hard reset, pressing the power button for 30 seconds, also did not solve the problem. The display works fine with the same USB-C cable on my HP EliteBook 840 G6, so the problem must be with the Omen 15 and its configuration. I would be very grateful for some tips and tricks...

Thanks......
