I thought this was fixed(haven't checked in a while). You can add the resolution manually.
Here an example for 1080p. Change what's needed for your monitor.
sudo cvt 1920 1080 60 Then you get something like : # 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync Everything after modeline you need to copy and past it behind : sudo xrandr -- newmod e Example : sudo xrandr -- newmod e "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync Then : sudo xrandr --addmode HDMI-1 1920x10 80_60.00 sudo xrandr --output HDMI-1 --mode 1920x1080_60.00
