Both show Nvidia graphics, however, no framebuffer, no display.
Unlikely macOS supports the LVDS switch.

On another forum, someone claimed to have managed to use dGPU instead of iGPU in Sierra 10.12 on a similar laptop;MSI GS43VR 7RE, mine is;MSI GE72VR 7RF it must be wrong since the only thing I've read here is that it doesn't work ?!

As a last attempt, I have installed latest drivers from NVIDIA and turned on my dGPU (removed SSDT) IOReg attached just to be sure.


In Terminal it looked more promising :


audio_cloverHDMI-120_v1.0d\ 2.command
