Monitor unknown after upgrading to 18.04

[ubuntini2]

Hi
Have been running Ubuntu Mate 17.10 and just upgraded to 18.04 LTS.
But after upgrading my monitor settings are all wrong and can't set the proper resolution.
How can I resolve this?

The results of the following command lspci -nnk | grep -i vga -A3

Subsystem: NVIDIA Corporation GV100 [TITAN V] [10de:1218]
