[Ubuntu-x-swat] [Bug 1799613] Re: In kernel 4.14.59, monitor resolution is detected correctly. In kernels after that, they are not detected correctly.
I think that fixed it.
To add `amdgpu.dc=0`, you must edit your grub configuration

update-to-18-04#1032198

After doing this, the resolution is detected correctly and appears
normal in the 4.15.0-38-generic kernel.
