Manually adding resolution works.

$ xrandr --newmode 1920x1080 148.5 1920 2008 2052 2200 1080 1089 1095 1125 +hsync +vsync
$ xrandr --addmode DisplayPort-1 1920x1080
$ xrandr --output DisplayPort-1 --mode 1920x1080

Seems like the problem is related to detecting display modes.

Note that the display was able to handle refresh rate up to 144Hz.
