xrandrU mnie to wygląda tak:

Więc wiem, że chodzi o wyjście DP1-3 (ostatnia rozdzielczość to ta dodana). Teraz trzeba wygenerować wpis:
cvt 1680 1050Oczywiście liczby to rozdzielczość jaka nas interesuje. I to co po modeline dodać jako tryb do xrandr:
sudo xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
I ustawić tryb jako dostępny dla naszego wyjścia:
sudo xrandr --addmode DP1-3 "1680x1050_60.00"
