I am running Zorin 12.4 kernel version 4.15.0-46-generic
Video card is GeForce GTX 1060 6GB
Somehow my screen resolution settings got messed up.
Output of xrandr:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
If I boot into an earlier kernel version (4.15.0-30-generic) my screen resolution is perfect.
Output of xrandr:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
DVI-D-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm

DP-2 disconnected (normal left inverted right x axis y axis)

On reboot my system reverts to the later kernel version and does not recognise the monitor.
I have tried uninstalling and reinstalling the nvidia driver, no change.
