Dual monitors no longer detected

[zeeeva]

My dual monitors stopped working this past week and so far none of the troubleshooting from the HP Support Assistant or anything I have found online has helped. I have a 4 month old HP Spectre laptop running through an HP Thunderbolt Dock 120W G2 to dual Acer monitors that are roughly 18 months old. Everything was fine until I disconnected from the dock to take my laptop with me, a couple of days later(and at least one Windows 10 update) when I reconnected to the dock, the system can't detect the monitors. I have plugged the dock into my old Dell laptop and everything works fine so I know it's got to be something in the HP laptop. When I go to set projection I can click on extend, duplicate or second screen only and nothing happens. In device manager, I have updated, disabled, enabled, uninstalled, reinstalled, rolled back and so far nothing has worked. I've rolled back Windows updates, been to Nvidia's support and feel like I am beating my head against the wall, my next step is a reset, any advice or help is greatly appreciated.

Welcome to HP Community

I have gone through your Post and would like to help

Have you tried running the updates through HPSA?

Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

If the issue persists the next Step would be Reset

Keep me posted how it goes

Thank you and have a wonderful day 😊
