After update, laptop can not detect connection of multiple monitors

[JKB0103]

After an update, my laptop will not detect my external monitor. It also deleted my brighteness screen leverl, however I found the fix for that, but I still cannot find the fix after this update. Can anyone help?  I have uninstalled the display adaptor and reinstalled, with no luck.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

To resolve this issue, perform the following steps:

1. Turn on the external monitor.

2. Open the On-Screen Display (OSD) Menu.

3. Uncheck No Input Signal Warning.

   

4. Confirm that the external display is now functional.

Hope this helps! Keep me posted for further assistance.
