MacBook Pro (16-inch, 2019) doesn't recognize 2nd monitor I bought two Dell S-Series 27-Inch monitors and they both display the image, the problem is that they are mirroring each other, it's like it doesn't find the other monitor.  This is the docker I'm using

What I tried:


Reset SMC
Bootcamp (works excellent, I can see the two screens how it should be)
General info
Updates (there are none, it's up to date)
Reset NVRAM
Pressing Option -> "Detect Displays" on bottom right corner


Look below:



That's with the lid open, if I close it, it only shows me this:



Now what I wonder is why are those two profiles there? Is it recognizing the other monitor but not doing anything?
EDIT: the profile doesn't seem to be involved in this, still not 100% sure

Any ideas?
Not sure if this would work for you, but my MacBook Pro was not detecting a Dell 2nd screen while my buddy's older MacBook Pro did.
All I had to do was reseat the cable on the monitors side - the pins were a bit loose and I just tightened them all the screws all the way.
