I don't know if this will help, but I have an old Centrino i5 mobile running 4.18.1 as a media pc and if I connect an external monitor and boot I get a hard crash of the PC. I managed to get a complete dmesg just before the hang.
This PC is intel only, not dual video.

I'm using this PC at the moment, on the external monitor which works fine if I plug it in after X has started.
I'll try to keep tabs on this thread.
This is a Gentoo install.
