This was all in 20-amdgpu.conf originally, doesn't matter if I add
monitors+screen or not. I have to run these commands after every restart, or no
signal:
xrandr --newmode "mymode" 148.35 1920 2008 2052 2200 1080 1084 1089 1125
+hsync +vsync
xrandr --addmode DVI-I-1 mymode
xrandr --output DVI-I-1 --right-of DVI-D-0 --mode mymode</pre>
