I have a dedicated GPU (amd polaris 10 - amdgpu) and an integrated one.(intel hd530 - i965)
i wanted to virtualization pass-through with qemu and guest win10

Then my first monitor(dell u2414h) is connected to the GPU, and the second one(eizo s1931) is connected to the integrated GPU.
But my gentoo plasma not detects the eizo s1931 monitor (no dual monitor) i can't find the solution after a couple of days surfing and comparing kernel options.

I try several live isos:
manjaro detects well the both
void linux have same problem that my gentoo
slackware detect well the both
windows10 detect well the both
calculate not starts xorg system

PLASMA DISPLAY CONFIGURATION:
wrong igp screnn detection----> gentoo https://i.imgur.com/IVALftD.png
right igp screen detection------>slackware_live https://i.imgur.com/3G2cAcj.png
