[Bug 1799613] Re: In kernel 4.14.59, monitor resolution is detected correctly. In kernels after that, they are not detected correctly.

OpenSuse didn't work out. I re-imaged with a totally new distro and ran
into this.

Booting from GRUB into 4.14.59 allows my two monitors to run at their native resolution, 2560x1440. Any newer kernel does not allow my two monitors to run at their native resolution, only allowing up to 1920x1200.
