Cannot detect external HP monitors via HP Universal USB-C Multiport Hub

[msacco]

Two weeks ago, my Omen laptop ceased connecting to my two external monitors.  I tried going through the set-up process and Windows cannot detect the monitors.  Oddly enough, the mouse and keyboard both work and they are connected via the USB-C Multiport.  Additionally, I attatched another HP laptop to the USB-C Multiport and both external monitors work fine.

Hi @msacco,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

It seems like the issue might be specific to your Omen laptop. Here are some steps you can take to troubleshoot and potentially resolve the problem.

• Update Graphics Drivers: Ensure that your graphics drivers are up-to-date. Visit our HP website or the graphics card manufacturer to download and install the latest drivers.
• Check Display Settings: Open the Display settings in Windows and check if the external monitors are recognized. Right-click on the desktop, select "Display settings," and see if the additional monitors are listed. If not, try clicking on "Detect" to see if Windows can find them.
• Check Device Manager: Open Device Manager and check for any warnings or errors related to your graphics card or display adapters. Right-click on the Start menu, select "Device Manager," and look for any devices with a yellow triangle or exclamation mark.
• Reconnect Cables: Disconnect and reconnect all cables between your laptop and the external monitors. Ensure that the connections are secure and that there are no damaged cables.
• Power Cycle: Shut down your laptop, unplug it from power, and disconnect all external devices. Wait for a few minutes, then reconnect everything and power on your laptop.
• BIOS/UEFI Update: Check if there is a BIOS/UEFI update available for your laptop on the HP website. Sometimes, firmware updates can address compatibility issues.
• Try Different Ports: If your laptop has multiple USB-C ports, try connecting the USB-C Multiport to a different port to see if the issue persists.
• System Restore: If the issue started after a recent software update or installation, you might consider performing a system restore to a point before the problem occurred.
• Check for Windows Updates: Make sure your operating system is up-to-date by checking for and installing the latest Windows updates.

Remember to back up important data before making significant changes to your system.

I hope this helps. 
 

Take care and have a good day.
