no problem, I should have looked at the console output earlier. would you just like to tell me which other port I can choose?

There is an error in the second console output. This one:

listen EADDRINUSE:  address already in use  128.0.0.1:8080

thats correct!

I have done that but it still uses 1 config file. I have found that it always uses the config file of the MagicMirror that I run first.

I used npm start to start both displays

I have done npm start on both

I found the error, because I put the 2 screens on top of each other, not x but y = 1920.
But I have found that the magicmirror2 folder is listening for the config file of the magicmirror folder. How can I adjust this?

Thanks for the quick respons
Yes, exact like that.

@sdetweil I addded electronOptions: {x: 1920} to my config file and I didn’t get an error but it still only shows up on the first screen. Am I doing something wrong?

@sdetweil thanks for your quick and very complete answer. But do I understand that it is not possible to run the software on 2 screens? Could it be possible to run a separate magic mirror on each screen?
