I can confirm that it is this one port, as all of the others work. I have confirmed this with 2 different monitors and 2 different usb-c to HDMI adapters. If I plug regular USB devices into this port they work fine, just video is failing.

I have reset the PRAM/NVRAM.

I'm running 10.15.6

Any other thoughts on how I might remedy this?
 
It does not seem that it would help since you already confirmed that the other ports do work but maybe try to completely disconnect the monitor from the power source for several seconds and try again. This sounds stupid but i had a similar problem with a usb c monitor which would not display anything and a complete reset did help!
