Hey guys, I got a DisplayPort problem, external monitor works fine until I unplug the miniDP cable, then the internal screen turns to black immediately, only the backlight left. But kernel still running, I run gen_debug through my phone
After that, when I shut down, kernel hanged, I have to cut power. (this only happens when i unplug the miniDP)

BTW HDMI don't have this issue, whatever i plug/unplug, internal screen works fine and the kernel won't hang.

My Laptop on Mojave 10.14.6 (18G87):
MSI GL62M 7RD-223CN
CPU: i7-7700HQ / HM175
GPU: HD630, 1080p on eDP
1x Mini DP port
1x HDMI port

I will attach detail port info screenshot

PS:
I use ig-platform-id 0x1916000 cause i will black screen if i use Kaby lake id.

Any help are appreciated.

have you tired to use an ig-platform for a laptop? unless you made a typo, it would have been: 0x19160000 but that is for a desktop

0x191b0000 is for a skylake laptop

Thanks for your reply!
That's not a typo, i found it on pinned thread: https://www.tonymacx86.com/threads/readme-common-problems-and-workarounds-on-10-14-mojave.255823/
I'm going to try 0x191b0000, wish me luck.
