My problem is I would like to change the native resolution of the built-in screen of my MBPR 2015 running Mojave to 1920 * 1080. The thing is I don't want the output to be scaled, I just want this resolution to gain performance. Any way to achieve this ?

Thank you

    Changing the resolution is unlikely to improve performance.

    The native resolution of the display on a MBP is what it is and cannot be changed, only scaled.

  • are you sure about that ? I am sure there must be some kind of hidden file to modify the native resolution, or at least a trick to make the built in screen behave like an external one...

While you can't "change the native resolution", you can use the displaymode command line tool to change to the native resolution instead of scaled resolutions.

Download the displaymode binary from the "releases" section on github, and extract it if necessary. Then from Terminal.app, cd to the directory the displaymode file is in and run:

./displaymode t 1920 1080

You can also run:

./displaymode d

to get a list of supported resolutions.
