Cannot connect external monitor via HDMI

hp spectre touchsmart 15-4010
Microsoft Windows 10 (64-bit)

Hi - I am not able to connect an external screen to the laptop.

 

Nothing happens when I connect the screen to the laptop. Screen says: no signal. Laptop does nothing. Mirring says didn't found another screen.

 

Might be realted:

Ther is an error in Device Manager: ISB-IF xHCI USB Host Controller has an exlamation mark in a yellow triangle.

 

Thanks,
Zoltan
