Windows 10: Windows 10 - 2nd monitor not detected after update

I have a Surface Pro 3 with Windows 10 and Office 365. Just completed the latest update (1803) and now it will not detect the 2nd monitor. I have tried rebooting, running the Troubleshooter for Hardware and Devices - nothing. I have tried connecting the 2nd monitor direct to the tablet as well as thru the docking station. Worked fine before the update

2nd monitor not being detected

Received a software update for windows 10. Upon restart my 2nd monitor was no longer working. Went to the display section in Settings and it is not being detected. Pushed the detect button and nothing. How do I get this back. My 2nd monitor is more
important than any new things in the update.

 

Windows 10 stopped detecting 2nd monitor

I've restarted the computer (several times), and it's not showing any signs of detecting the 2nd monitor.

Ever since it stopped working, there's only '1' Display option; clicking 'Detect' in Multiple displays results in the message
"Didn't detect another display"; the Device Manager only lists one monitor (screenshot below); and it has stopped allowing me to select other projection modes unless I connect to the 2nd monitor wirelessly.

I'm using an HDMI cable for the 2nd monitor, and have tried both HDMI ports on the monitor unsuccessfully. The monitor models are Dell E2414H and LG 24J4840.

Windows 10 Not Detecting 2nd Monitor

this recommendation is useless. I followed every step and the troubleshooter said no problems detected. When I had Windows 8.1 I was able to simply plug in my monitor (HannsG 28") via micro HDMI port and it was able to detect it. But Windows 10 does not detect
my second monitor. The system just does not see it.
