Solved!

External Monitors not recognized by Thunderbolt Dock

HP Recommended
HP Spectre x360 Convertible 15t-eb000
Microsoft Windows 10 (64-bit)

I have a HP Spectre x360 Convertible 15t-eb000.  I have a Plugable USB-C Dock 14-in-1 with Thunderbolt 3. (TBT3-UDZ).  I cannot get an external monitor to work.  My HP has Thunderbolt software, application version 1.0.30.0.  Controller driver version 1.41.823.0.  Thunderbolt generation 3 (15EB). NVM Firmware version: 54.0. Connection status: Connected.

 

My monitor is a ASUS VS247H-P. I tried to connect with a HDMI - HDMI cable and a HDMI - DisplayPort  cable. The monitor says No HDMI signal and my laptop does not recognize a second display.

 

I connected a speaker to the dock and it does work.

Thanks for feedback. The Plugable - DisplayLink tech support gave me the same advice, and it worked.

When I execute the file sp108735.exe, the window that appears says that the Bios Update is not compatible with this device. The window says that the utility is supposed to update BIOS to version F.42.

@rfgraham,

 

The docking station referred is a commercial model & the unit is a consumer segment. The said combination is not tested by HP. So, the functionality is not guaranteed.

Hi Rfgraham,

 

I have the exact same model and had the same problem with a different docking station, Amazon.com: VAVA USB C Docking Station, 12-in-1 Type C Hub with Dual 4K HDMI Ports, RJ45 Ethernet, 4....

 

I installed an older version of the Nvidia Graphics driver from HP's website, version 26.21.14.4276, 

HP Spectre x360 Laptop - 15t-eb000 CTO Software and Driver Downloads | HP® Customer Support

 

This updated the display driver which resolved the issue.

 

Hope this helps,

 

Regards
