Commen= t # 7 on bug 10230= 0 from Michel D=C3=A4nzer 
According to the log file, the ASUS monitor only lists the 60 =
Hz 1920x1080 mode
in its EDID. So it seems clear that's what the monitor wants to be fed, but=
 for
some reason we don't seem to be generating it properly.

Any chance you can try if a kernel built from the amd-staging-4.12 or
amd-staging-drm-next branch of https://cgit.freedesktop.org/~agd5f/linux/ with
CONFIG_DRM_AMD_DC=3Dy works better?
