I also wonder if Xorg itself is trying to apply sanity checking and
ignoring the top mode thinking it can't be true:
Modeline "Mode 1" 580.08 2560 2608 2640 2720 1440 1443
1448 1481 +hsync -vsync

Title:
[amdgpu] monitor refresh rates higher than 120 Hz not detected/cannot
be set
Status in xorg-server package in Ubuntu:
New
Status in xserver-xorg-video-amdgpu package in Ubuntu:
New
Bug description:
using this monitor: https://www.pixiogaming.com/px329
and this video card:
https://www.gigabyte.com/us/Graphics-Card/GV-RX580GAMING-4GD-rev-10-11
I am unable to set any refresh rates higher than 120 Hz. The video
card and the monitor both support 144 Hz and 165 Hz yet those refresh
rates are not available as options to choose in the settings app.
I've tried a couple of online guides using xrandr to add and set a
custom display resolution/refresh rate but I can't get it to go any
higher than 120 Hz. I have the exact same hardware running macOS
Mojave 10.14.4 and it allows me to set the refresh rate to 144 Hz and
165 Hz.
