Macbook Pro 2012 (15inch Retina Display)

Ok, so this is my question. I just installed Manjaro i3wm community edition and when i connect external display with usb both displays works (main and external). But there is a problem with my external display, a lot of glitch, thearing and lags, cause b by default there is no nvidia drivers installed. When I installed driver, another problem appears, now my external monitor is only blank. Is there any way to resolve this? Which kernel, which driver for my nvidia gpu?
Here is my Macbook configuration

please boot into manjaro, open a terminal and run the following command

inxi --admin --verbosity=7 --filter --no-host --width

please copy the infos here using the option “preformatted text” where you paste the infos to.

@Olli Well, now I’m not even able to boot into manjaro live usb, last line say “Arbitrary executable file formats file system” and I’m stuck there.
