External Second Monitor not detected after Bios Update

Hello All!

I have a new HP Spectre x360 convertible laptop and a Dell s 2740 external monitor.

I restarted my machine and the bios updated happened automatically. Once it happened, I could not use my Dell monitor at all.

It says "there is no signal coming from your computer. Bla bla bla ………"

Steps taken-

For now, I have uninstalled the display driver and reinstalled it after restarting.

Changed HDMI cable and USB-c hub.

Does anyone know the resolution? Please help!

I understand the inconvenience you are facing with accessing the external monitor in Windows 10, we will help you with this issue.

As you have tried most of the troubleshooting steps, let us know the following to assist you better:

• What exactly happens when you try to connect to the external display?

Step 2: I suggest you to remove all the external devices except mouse and keyboard and try to perform clean boot to check if there is any issue with the device and to avoid any third party software conflict.
