looks like you have the xrandr syntax wrong and you don't need to run it sudo either.
first introduce the mode to xrandr
xrandr --newmode 1920x1080_60 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
Then assign it to the relevant output (e.g. hdmi, dp1 , vga)
xrandr --addmode VGA-0 1920x1080_60
Then make the output use the new resolution
xrandr --output VGA-0 --mode 1920x1080_60
