Hello,

I have an issue with connecting external monitor over USB-C. It actually works well only for first start after "hard reset" (holding the power button for aprox 30sec). In this case external monitor over USB-C working fine including all the periphery devices.

 

In moment that I reconnect the USB-C cable or wake the NTB from sleep, monitor shows message "DP Unsupported" and monitor don't work at all anymore. I have not found any way how to make it working again except of "hard restart". I have even updated drivers from HP support web which are related to DP over USB-C.

 

Monitor is 4k EIZO Flexscan EV3285.

 

I could not hard restart NTB each time when I came back to office.

Work around is to connect monitor via HDMI but as I use monitor as docking station I need to use monitors USB ports for accessory.
