16.04 + Nvidia drivers won't work with dual monitors

[DesertJim]

been trying to get my dual monitors working on Ubuntu 16.04 LTS and a nVidia GeForce 960 using 361.42

Server version 11.0
Server Vendor version 1.18.3
NV Control version 1.29

Can only get one to display the desktop. Whichever is plugged into the DVI-I port, the other is not recognised whether it is in the DVI-D or HDMI (using converters to VGA)

I can move the mouse to the blank screen where it shows as a large (but moveable) X

Tried ubuntu forums for a solution but no improvement
