External monitor not detected by HP Spectre X360

[DomerSquared]

I have a 15" X360 with i7-8750H, 16GB RAM, Windows 10 Pro x64, and Envy 27 inch monitor.  Laptop is connected directly to the monitor with USB-C cable.  I had everything working for several months.  I have not installed any new software.  Now the display is not active.  The HP MY Display app sees the monitor but Windows Display settings does not.

The Envy display sees the USB-C connection when it starts but shuts down with an message that it does not see a signal.

Have you tried to use a different cable?

Did you try to update the drivers either using Windows update or using HP Support Assistant.

Waiting for your response!

Not sure why it stopped working.  It was not a cable issue.  I updated the BIOS and the problem was resolved.  I am not sure why that fixed the issue but it did.
