HP Spectre USB-C Travel Dock problem: HDMI output keeps disconnecting and reconnecting

[motak]

I am connecting my HP Spectre x360 laptop to an HP Spectre USB-C Travel Dock, and connecting the HDMI output from the dock to my Samsung external monitor. A few times a minute, the monitor randomly flashes black, disconnects, then reconnects. This renders the external monitor unusable. I tried this with a different monitor and the problem is the same.

When I connect my external monitor directly to the laptop via a USB-C-to-HDMI adapter, the monitor works fine. So it is clearly a problem with the Spectre USB-C Travel Dock.

I have updated the firmware on the Spectre USB-C Travel Dock, but the problem stayed the same.

Your help is appreciated.

@motak You seem to have narrowed it down to be a malfunctioning USB Dock and you've done a great job at it,

I suggest you talk to HP support and discuss your options, follow the below steps to get started:

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
