When I change my input source of my monitor, for e. g. from hdmi to dp then back again, the external monitor Dell u3415w will not be reactivated and you can just restart the computer.

 

Important for the solution, as soon as you change the source the internal monitor will be deactivated and come never be back.

 

I have an e7470 and enclosed you can find my clover

Ok, last I tested I don't remember having the issue you describe. I'll test and report back when I have time.

In the mean time you could try updating with my latest Catalina bootpack. Replace the serial # to the new config if you have it working with iMessage...etc
