@sdetweil This was what I needed! Many thanks for helping me with this problem! Issue solved!

@sdetweil , thanks for the reply. I did some adaptations in the electron.js file, as I couldn’t find any specific settings in the config.js file. That’s why I thought maybe the electron.js file was the correct file to change? By changing the electron.js file, I already could change the full screen setting. So now I can have a smaller screen when I do the MagicMirror start (npm run start). Then I can manually adapt the length of the screen/frame so it is spreaded over the 2 monitors. Only remaining problem is when I close the MM app and I start again (by using npm run start), I still have the smaller screen and I again need to manually change the dimensions so the screen would fill the 2 monitors. Do you have any idea how that can be fixed? Thanks!

I want to have the MM on 2 screens. I want to have both screens alligned above each other so I can have a big surface to present the MM app on the left side of the mirror. But then the MM app should be shown on both screens, so it would look like these 2 screens are 1 big screen.

Thanks for the reply. So if I understand correctly, I should add this file in the MagicMirror folder and then I can proceed the steps mentioned in the other topic? Is that correct?

Only thing I should keep in mind is not to use the “npm run start” command any more, but copy paste the link to start the application?

Sorry for the questions, but I’m a little uncertain how to fix the dual monitor problem.

Re: Rpi 4 and two monitors

Hello guys, I’m new here and I started on the MagicMirror some weeks ago. I have 2 old monitors that I would like to use but I’m having some issues to get the MagicMirror app on the 2 screens. I was following the steps of an older topis (Rpi 4 and two monitors), but I was stuck at a certain point, because I can’t find the run-start.sh in the folder structure. Can somebody help me so I can try to have it working on both screens? Thanks guys!
