Hardware: Raven Ridge 2200G Asrock A320M-HDV. Manual states max resolution for DVI 1920x1200@60 which is single link, however the board's DVI socket is clearly dual link. Monex WQHD which is known to work @ 2560x1440@60 with reduced blanking since it works on Intel Haswell with the i915 drivers. This monitor has only one input, which is dual link DVI. See below for edid-decode output. Dual channel DVI-D cable. This is a dual monitor setup. The other monitor is 1920x1080 over VGA/D-SUB. Software: ubuntu bionic beaver with linux kernel 4.16.0-rc5+ and ppa:oibaf/graphics-drivers /lib/firmware/amdgpu/raven_gpu_info.bin is present (316 bytes). No customisation of xorg configuration files.
