Multiple display resolution issue on lock screen

Question

So i just downloaded the Loki 0.4.1.

The issue is that when I lock the screen with an external monitor connected to my laptop (it has a different resolution), the lock screen tries to change resolution multiple times during its black screen process which results in slower locking and if I have sound going through eg spotify the sound freezes multiple times, althoguh it continues afterwards

Is there a way i can disable the resolution change on lock?

Also note that I have installed the latest nvidia driver (390)

Go here, it fixed the issue for me. Ensure you note carefully the outputs when you grep using xrandr. They are key to the bash script.

Pantheon-greeter login screen has incorrect resolution on external monitor

My code example:

#!/bin/bash

Samsung="$(xrandr -q | grep 'HDMI-1 connected' | awk '{ print $1 }')"
if [ "$Samsung" = "HDMI-1" ]; then
  xrandr --output LVDS1 --off
  xrandr --output HDMI-1 --primary --mode 1920x1080
