> For integrated displays:

goto your terminal and type vim ~/.profile ENTER
Paste in the shell command from step 5 and 6, then save.

> For external displays:

create a script called external_monitor_resolution.sh in the directory /etc/profile.d/. using sudo vim /etc/profile.d/external_monitor_resol.sh.
Paste in the shell command from step 5 and 6, then save.
(Note: if using sudo would require you typing a password, your system might freeze on startup while waiting for you to input a password. So when pasting do away with the sudo) 
Something like this:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-1 "1920x1080_60.00"` and <kbd>ENTER</kbd> *(replace **VGA-1** with your display type (step 3) like **HDMI-1** or **DP-1**)*
