Second monitor not detected after Windows upgrade despite driver update

[MXM]

On Thursday night, my HP Envy did an upgrade and shut down. When I turned it on Friday morning, the second monitor, which is connected via HDMI, was no longer detected, even though have it selected on Extend mode.  My IT department made sure the driver was updated but even then could not get it to work.  They suggested I use a Plugable USB 3.0, which I connected today but it also does not detect the monitor (although it works fine - using it for keyboard and mouse).  I have uninstalled the Intel(R) HD Graphics 4600 and re-installed it, ensured it was updated, etc.,  but nothing is working.  The monitor is in working condition (and turned on) and the HDMI cables are fine (have used two different ones).  Any ideas?

Thank you for your response, Esteban. I ended up resetting the laptop and that took care of the issue.
