Ubuntu - Display - Set a different resolution

Set a different resolution

Use xrandr to set a different resolution. 

xrandr --output HDMI-1 --mode 1920x1080

NOTE: The resolution must be list if supported resolutions.

  • Changes made using xrandr will only last through the current session.

Set a different resolution, when multiple refresh rates are present in the list

When multiple refresh rates are present in the list, it may be changed by the –rate option, either at the same time or independently. 

xrandr --output HDMI-1 --mode 1920x1080 --rate 60

Set to the maximum resolution

Use the –auto option. 

xrandr --output HDMI-1 --auto

Set to the resolution for multiple monitors

It is possible to specify multiple outputs in one command, e.g. to turn off HDMI-1 and turn on HDMI-2 with preferred resolution: 

xrandr --output HDMI-1 --off --output HDMI-2 --auto
